http://www.bricsys.com/bricscad/help/en_US/V13/CmdRef/source/U/Units/Units.htm


2.3 Pagina de plotagem

Veja WebHelp ou Anexo. Precisamos definir a pagina basica de plotagem. Command Bar :page-setup (vai a Figura 2.3) ou Menu Tools :: Drawing Explorer :: Page Setups (vai a Figura2.3) clique no ıcone o *Layout1* (vai para Figura 2.4) e configure conforme mostrado. Surgira aaba do Layout1 onde construimos a prancha e organizamos a ’viewport’ veja Figura 2.5.

2.4 Escala do desenho

No layout, folha de impressa, as medidas sao em milimetro. No desenho consideramos metro.Entao temos uma diferenca que e ajustada pela escala. Considerando o desenho impresso no




http://www.bricsys.com/bricscad/help/en_US/V13/CmdRef/source/P/PageSetup.htm


papel A3, 420x297 mm. Para saber a escala da ’viewport’ usa-se:

Escala =MedidaReal

MedidaImpressa(2.1)

Ecala =30m

0.420m(2.2)

Escala = 71.429 ≈ 100 (2.3)

(2.4)

Ficando a escala deste desenho em 1:100.

2.5 Ajustando o desenho na ViewPort

Veja WebHelp ou Anexo. Estando no ’layout’ de um clique duplo sobre a ’viewport’. Veja oCommand Bar no Arquivo 2.5 ou Figura 2.5. O desenho foi ajustado na escala 1:100 dentroda area de impressao desejada. O valor 1000 e necessario para ajustar uma relacao entre m dodesenho e mm da impressao.

2.6 Definindo altura das letras

Considere o modelo:

HCAD =Hreal ∗ Escala

UnidadeMetrica(2.5)

HCAD =2mm ∗ 100

1000= 0.2 (2.6)

HCAD =5mm ∗ 100

1000= 0.5 (2.7)

Sendo: HCAD: altura da letra que sera configurada no CAD. Hreal: altura real impressa daletra, em mm. UnidadeMetrica e a unidade definida no desenho que foi metro, 1000.

A unidade metrica e sempre em relacao ao mm de impressao. Veja Tabela 2.1

Tabela 2.1: Dados para analiseMetro Decimetro Centımetro Milimetro1000 100 10 1

Via Command Bar digite :explorer selecione Text Styles ou Menu Tools :: DrawingExplorer :: Text Styles. Configure conforme Figura 2.6.

Instalando o Linux e outros Softwares

Prof. Dr. Catalunha

Atualizado em 4 de Dezembro de 2013

1 Introducao

Nas minhas disciplinas sao adotados obrigatoriamente algumas ferramentas computacionais paraauxılio no processamento dos dados. Seguem alguns orientacoes para melhorar instalacao e con-figuracao destas ferramentas.

Estaremos desenvolvendo todas as atividades na plataforma linux, ubuntu, utilizando o ’ter-minal’ como interface de entrada e saida. ’Nautilus’ como navegador de arquivos. ’Chrome’ comonavegador de internet. ’gedit’ como editor de texto para relatorios e programas.

Para processamento matematico numerico e ambiente de linguagem de programacao sera ado-tado o OCTAVE.

O processamento matematico simbolico sera desenvolvido no MAXIMA.As analises estatısticas serao desenvolvidas no R.A geracao de graficos, em formato ”png”sera feita por padrao GNUPLOT. Caso seja necessario

o OCTAVE, MAXIMA ou R pode ser adotado para geracao de graficos.O Libre Office sera adotado como ferramenta de escritorio para formatacao complexa em textos,

uso de planilhas, confeccao de ”slides”para apresentacao e desenhos. Somente para trabalhosespecıficos quando solicitados.

2 Sistema Operacional

Estaremos desenvolvendo todas as atividades na plataforma Linux, Distribuicao Ubuntu, o siteoficial e (http://www.ubuntu-br.org/). Instale os programas anteriormente mencionados conformeorientacoes do item 3.

Voce podera utilizar o linux no pendrive, item 2.2, ou mesmo instalar no hd de seu computador,item 2.1. Recomendo instalar no seu hd pois a demanda de trabalhos neste ambiente sera grande,e o pen-drive por lhe trazer alguns atrasos.

Nos tutores que se seguem usaremos muito o termo “*.iso”, que quer dizer um imagem dedados pronto para ser gravado em pendrive.

2.1 Usando o Linux instalado no seu HD/Computador/Notebook

Caso possua um computador e queira instalar o Ubuntu, voce nao perdera o seu windows, o Linuxcria uma area no hd para ele e gerencia a inicializacao permitindo que voce escolha entre Linuxou Windows.

1

Linux e outros Softwares Prof. Dr. Catalunha

Para este processo e interessante a presenca de um amigo da ciencia da computacao para tirar algumas duvidas que possam surgir ou resolver algumas situacoes anormais, mas o processo e simples. Lembre-se antes de salvar seus dados do Windows em “backup” externo. E faca “backup” perıodicos.Os passos sao:

1. Estando o Windows instalado em seu Computador/Notebook.

2. Para instalar o Linux em seu HD ele precisa estar instalado num pendrive, para isto siga asorientacoes do Item 2.2 e depois retorne a esta etapa;

3. Inicie o computador, de boot, pelo pendrive.

4. Selecione a opcao ”Instalar em HD”.

5. Responda as perguntas de instalacao conforme desejar.

2.2 Usando o Linux apenas no PenDrive

Voce pode usar esta distribuicao no pendrive, e muito simples. Voce nao perde o uso do pendrivepara windows, carro, aparelho de som ou outras aplicacoes.

Alem de permitir que voce possa instalar programas no linux do pendrive e guardar arquivoscomo se estivesse num linux instalado no seu hd. Voce tambem acessa ao hd windows normalmente.

Para isto siga estes passos:

1. Pegue a imagem iso do ubuntu no site oficial e copie para um pendrive no mınimo 4GB.Verifique se seu computador e 64bits ou 32 bits.

2. Acesse a um computador Linux em qualquer lugar, pois vc precisa criar o disco de inicia-lizacao e precisa de uma maquina linux para isto. Copie a imagem iso do ubuntu do seupendrive para este computador.

3. Formate este pen drive. Retire e incira ele de novo no computador para reconhece-lo.

4. Neste mesmo computador abra o terminal e digite: usb-creator-gtk. Abrira entao uma janelacomo a da Figura 1.

5. Primeiro selecione a iso que voce baixou e foi salva no computador, pois esta sera a versaoque sera instalada no pendrive, veja letra A na Figura 1.

6. O pendrive ja foi reconhecido veja letra B na Figura 1.

7. Selecione ”Armazenados no espaco adicional reservado”, veja letra C na Figura 1. Movaentao a barra ate aproximadamente 100% da mesma.

8. Clique em ”Criar um disco inicializavel”, veja letra D na Figura 1. Apos este procedimentovoce tera um linux completo num pendrive.

9. Inicie o seu computador, de boot, pelo pendrive.

10. Selecione a opcao ”Testar ubuntu”.

11. Responda as perguntas de instalacao conforme desejar.

12. Pronto, vc ja tem um linux via pendrive em seu computador. Selecione apenas testar.

O Ubuntu necessita apenas da instalacao dos demais programas Octave, Maxima, Gnuplot, R.Conforme veremos em seguida.

3 Instalando Softwares Diretamente

Pode acontecer de voce ter um linux em seu computador e queira apenas instalar os softwares dadisciplina, veja os itens a seguir.

O gedit e o editor de textos padrao do ubuntu, ja vem instalado em todas as distribuicoes.

3.1 Instalando OCTAVE:

Para instalar no linux, e muito simples, atualize os repositorios e instale o software com os seguintescomandos no terminal:

1 $ sudo apt -get update

2 $ sudo apt -get install octave3 .2 octave3.2-doc octave3.2-info

octave -symbolic octave -odepkg octave -statistics

Linux e outros Softwares Prof. Dr. Catalunha

3.2 Instalando MAXIMA e GNUPLOT



2 $ sudo apt -get install maxima maxima -doc xmaxima

Apos esta operacao o Gnuplot tambem estara atualizado, pois o maxima precisa dele em suasbibliotecas graficas.

3.3 Instalando R



2 $ sudo apt -get install r-base

3.4 Instalando o Geogebra



2 $ sudo apt -get install geogebra

3.5 Instalando o BricsCAD

Para instalar no linux e simples. Acesse ao site, http://www.bricsys.com/, cadastre-se, baixe aversao que desejar e clique em instalar.

3.6 Instalando o Latex



2 $ sudo apt -get install texlive texlive -latex -extra texlive -lang -

portuguese texlive -math -extra

Agora precisamos instalar um editor que nos ajudara a compilar os textos em latex.

1 $ sudo add -apt -repository ppa:gummi/gummi


3 $ sudo apt -get install gummi

4 Atualizado em 4 de Dezembro de 2013

Prof. Dr. Catalunha Linux e outros Softwares

3.7 Instalando o LibreOffice

Ja e nativo do Ubuntu a presenca deste software em sua barra de ferramentas, contudo caso queirainstalar uma versao mais nova use este procedimento ou pesquise outro no google.

Para instalar no linux, e muito simples, atualize os repositorios e instale o software com osseguintes comandos no terminal:

1 $ udo add -apt -repository ppa:libreoffice/ppa

2 $ sudo apt -get update && sudo apt -get -y dist -upgrade

3 $ sudo apt -get install libreoffice libreoffice -l10n -pt-br

libreoffice -help -pt -br

3.8 Instalando o PHP/PostgreSQL/mysql

Como nao uso estas ferramentas diretamente em minhas disciplinas, nao constei aqui seu pro-cedimento de instalacao. Contudo uma rapida consulta no google nos permitira instalar estessoftwares com tranquilidade e qualquer coisa estou disposicao.

4 Outros Topicos

4.1 Melhorando o nautilus

Nautilus e o navegador de arquivos do Linux. Para acrescentar a possibilidade de abrir a pastacorrente em um terminal instale um plugin com o seguinte comando no terminal:

1 sudo apt -get install nautilus -open -terminal

4.2 Cache do navegador

Quando o nagevador de internet faz um download de um arquivo pela primeira vez ele guarda umacopia no cache, deposito auxiliar de armazenamento, com isto quando vc tenta fazer um downloaddo arquivo novamente, nagevador de internet ao inves de usar a internet e sobrecarregar a rede elepresume que vc queira o mesmo arquivo anterior e busca do cache interno do computador local.

Por isto alguns de vcs tentam fazer um download da ”Roteiro.pdf”da disciplina, formulariosou outro material e encontram o mesmo com uma versao desatualizada. Portando precisamosdesativar o cache para fazer um download sempre do arquivo mais atualizado da internet.

Apenas para o navegador de internet Chrome. Quando for baixar um arquivo da disciplinaprimeiro precione junto as teclas ”Ctrl - Shift - Delete”que o Chrome abrira uma janela pedindoautorizacao para limpar dados de navegacao, marque somente ”Esvaziar o cache”e clique emlimpar dados. Voce ira baixar o arquivo mais recente da disciplina.

Resumos e Formularios padroes

Os resumos do Linux e CAD sao apresentados em anexo.Quaisquer outras orientacoes neste item serao atualizadas e informadas aos alunos.

30

LinuxEste material é um auxílio de consulta rápida, o conhecimento aqui

apresentado deve ser fundamentado pelas atividades de aula e principalmente pelas bibliografias fornecidas. Cada disciplina demanda parte do

conhecimento aqui resumido, devendo o aluno estar apto a distingui-la.

1) Terminal 1.1) Comando básicos no terminal Linux. Maiores informações podem se obtidas em “man [comando]”.

COMANDO BÁSICO DESCRIÇÃO RESUMIDA

cd pasta/ vai ao caminho especificado.

cd .. acessa pasta anterior

ls lista resumida dos arquivos

ls -la lista todos os arquivos com todas as informações

pwd lista o caminho atual

clear limpa o terminal

eog arq.png aplicativo para abrir arquivo de imagem png

mv arq1 arq2 renomear arquivos

cp -fr arq1 pasta/ copiar arquivo para outra pasta

rm -fr arq pasta/ remove arquivo ou pasta completo

vim arq editar arquivo

mkdir pasta criar pasta

find . -name '*nome*' procura por pasta ou arquivo abaixo da pasta atual

grep -rin 'texto' ./* Procura texto dentro de arquivos abaixo da pasta atual

tail -n 10 arquivo Lista as ultimas linhas de um arquivo

1.2) Simbolos usados no terminal. Geralmente vemos esta linhaNomeDaConta@NomeDoComputador:~$

@ : separa nome da conta e nome do computador.~ : indica pasta do usuário atual, geralmente: /home/NomeDaConta$ : indica que o usuário atual não é administrador do sistema.

1.3) Na ilustraçãoA = Comando básico conforme item 1.1B = Acessar pasta da tarefa via terminal, ou pode ser via gerenciador de arquivos, Nautilus.C = Use o terminal apenas para acesso aos programas gnuplot, octave, maxima e rD = Abra cada um dos programas em uma aba separada.

2) Gerenciador de Arquivos – Nautilus 2.1) Um dos Gerenciadores de Arquivos do linux é o Nautilus. Quando selecionamos uma pasta, arquivo ou área vazia, sempre na janela a direita, podemos via menu suspenso (Botão direito do mouse) encontrar diversos comandos para manipulação, confira.

2.2) Na ilustraçãoA = Selecione a opção sempre de visualizar arquivos em árvore ou “tree”B = Crie as pastas via menu suspenso (Botão direito do mouse)C = Crie as arquivos via menu suspenso (Botão direito do mouse)D = Acesso ao terminal direto na pasta da tarefa via menu suspenso (Botão direito do mouse)

3) Editor de Textos - gedit 3.1) Na ilustração:

A = Os arquivos devem ser criados via gerenciador de arquivos, Nautilus. E abertos com clique duplo ou via menu suspenso (Botão direito do mouse) abrir com gedit. Não crie novo arquivo ou abra arquivo via gedit. Isto agiliza seu trabalho.B = Abra todos os arquivos de texto necessários a tarefa, neste editor.C = Ative a numeração das linhas via menu do gedit (Edit > Preferences > View > Line Number).D = Selecione as linhas com o mouse ou com a tecla [CTRL]+[Setas de Direção] e use a tecla [TAB] para tabular para direita e [SHIT]+[TAB] para tabular a esquerdaE = Verifique se o identificador de sintaxe esta correto, isto ajuda na visualização colorida do texto.F = A tabulação deve estar sempre em 2. Via menu do gedit (Edit > Preferences > View > Editor) selecione a opção substituir tabulação por espaço e endentação automática.

Command Options

Option Description

Print / Plotter Configuration

Selects the printer or plotter.

BricsCAD works with any output device installed on the system,including networked printers, print to file, faxes, and PostScriptdevices.

It also uses predefined printer parameters stored in PC3 files. SeePlotterManager command.

Edit plotter configuration Opens the printer's Properties dialog box for customizing the printer'sparameters.

Paper Size

Chooses the size of paper.

You can select standard sizes listed by the droplist; these are sizessupported by the printer.

While printer may appear to support many different sizes, you shouldselect only the size of paper that is actually in the printer.

If User Defined appears in the list, the paper's dimensions arespecified by the printer's Properties dialog box.

The image indicates the size, position and orientation of the currentplot area on the selected paper size.

Units Switches paper measurements between imperial and metric.

Plot Area

Specifies which area of the drawing to print:

View prints the current view or a named view. See Viewcommand.

Choose a view from the droplist:

Extents prints the extents of the drawing, which ensures everyvisible entity is printed.

Entities on frozen layers are not taken into account whencalculating the extents.

Limits prints the limits of the drawing, as specified by theLimits command.

Window prints a rectangular area of the drawing.

You define the rectangular area by entering x,y coordinatesor by clicking the Select Area to be Printed button.

Select area to be printed Specifies the rectangular area to be printed.

Click the button; the dialog box is dismissed temporarily, and youare prompted:

Select first corner of window specify one corner of the rectangle.Select second corner of window specify the other corner.You can pick points or enter x,y coordinates.

The Print dialog box returns, with the pair of x,y coordinates added to

06/12/13 PageSetup


the Windows Plot Area boxes.

Specifies the x,y coordinates of the lowerleft and upperright cornersof the rectangular area to be printed.

You can enter x,y coordinates, or click the button to pick points inthe drawing.

Plot Scale

Scales the drawing so that it fits the printable area of the paper.

The scale is calculated automatically by BricsCAD, and takes intoaccount the print area of the drawing.

The printable area is the size of the paper, minus the margins.

The margins are the strips along the four edges that the printer usesfor handling the paper.

When this option is turned on, you cannot specify the scale factor.

Specifies the scale factor of the printed drawing.

Choose a scale factor from the droplist, or select Custom to specify ascale factor.

1:1 prints the drawing full size, with no scaling.Custom allows you to specify a scale factor.

For scale factors like 1:5, the drawing is scaled smaller.

For scale factors like 5:1, the drawing is scaled larger.

Specifies userdefined scale factors.

For example, to print a drawing of 50'long house on paper 11" wide,enter:

Printed Inches = 11"

Drawing Units = 50'

BricsCAD works out the scale factor automatically.

Available scales in the list can be edited using the ScaleListEditcommand.

Scale lineweights If on, lineweights are scaled with respect to the plot scale.

Plot Style Table

Specifies the plot style table to use, which assigns properties to"pens," colors, and entities.

If the drawing does not use plot styles, then only CTB (colorbasedtable) files are listed.

If the drawing uses plot styles, then only STB (stylebased table) filesare listed.

When you switch from Non to a named plot style, BricsCAD promptsyou:

Assign plot style table to all layouts? click Yes or No.

Yes assigns the CTB or STB plot style file to all layouts.No assigns the plot style file to the current layout only.

Edit Plot Style Opens the Plot Style Table editor dialog box. See PlotStyle command.

This button is available only when the drawing uses STB plot styles.

Create New Plot Style Creates new plot styles; runs the Add Plot Style Table wizard.

If the drawing does not use named plot styles, then the wizardcreates new colordependent tables (CTB files).

If the drawing uses named plot styles, then the wizard creates newnamed plot style tables (STB files).

See StylesManager command.

Toggles the display of plot style names.

Drawing Orientation

06/12/13 PageSetup


Specifies the orientation of the drawing on rectangular paper:

Portrait The drawing or layout xaxis is aligned with theshortest edge of the selected paper size.

Landscape The drawing or layout xaxis is aligned with thelongest edge of the selected paper size.

Print upside down Prints the drawing upsidedown. This isuseful when paper with a drawing border is loaded backwards inthe printer.

Plot Offset

Specifies the offset distance for the print.

Enter positive or negative distances to move the drawing in the xand/or y distances:

Positive values move the drawing up and to the right.

Negative values move the drawing down and to the left.

The lower left corner of the drawing is moved by the specifieddistance.

This is useful when the paper has a title block area that might interferewith the drawing.

Centers the print on the page.

The center of the drawing is positioned in the center of the paper.

Together with Fit Print Area to Size of Page, these options areexcellent for prints were scale is unimportant.

Plot Options

Toggles the use the lineweights:

On mimics lineweights in the print.Off ignores lineweights.

This option is unavailable when Plot with Plot Styles is turned on.

Toggles the use of plot styles:

On uses plot styles determine the look of the printed drawing.Off does not use plot styles.

Plot styles override lineweight settings.

Toggles printing order:

06/12/13 Linetype

www.bricsys.com/bricscad/help/en_US/V13/UsrGui/source/10_Drawing_Entities/00_Entity_Creation_Settings/10_00_04_Entity_Line… 1/4


Entity Linetype

You use different linetypes to differentiate the purpose of one line from another. A linetype consists of a repeating pattern ofdots, dashes, or blank spaces. Linetypes determine the appearance of entities both on the screen and when printed. Bydefault, every drawing has at least three linetypes: CONTINUOUS, BYLAYER and BYBLOCK. Your drawing may alsocontain an unlimited number of additional linetypes. Linetype definitions are saved in the drawing. New linetypes are eitherimported from other drawings or loaded from a linetype file (e.g. iso.lin or default.lin).

New entities are drawn using the current lineweight.

Linetype BYLAYER:

Entities which have a linetype BYLAYER adopt the linetype of their layer. This allows you to change the linetype of all suchentities by adjusting the linetype of the layer.

Linetype BYBLOCK:

Entities created using linetype BYBLOCK, are drawn as continuous lines until you include them into a block. The entitiesthen inherit the block’s linetype setting when you insert the block into a drawing.

Linetype SCALE

Noncontinuous linetypes consist of lines, gaps and dots put together in a variety of patterns. In complex linetypes also textor shapes can be included. In the linetype definition the length of the lines and gaps are defined in drawing units. Todisplay the linetype correctly it needs to be scaled to match the dimensions of your drawing. The linetype scaling factor isdefined by the Linetype Scale (LTSCALE) system variable. BricsCAD will always put a dash at the start and end of a line,polyline, arc or spline. The linetype pattern is also nicely centered, so that both ends of the entity look the same.

Because linetypes are affected by scale, paper space becomes a problem. A linetype scale that looks fine in model spaceis possibly going to look wrong in paper space. This problem is solved by the Paperspace Linetype Scale (PSLTSCALE)system variable. When set to 0 (zero) or OFF, linetypes are scaled the same in model space and in layouts, when set to 1or ON, linetypes in layouts are drawn at the viewports scale.

Linetypes are normally generated from vertex to vertex. Polylines of which the vertices are very close together might berendered as a continuous line, if the linetype pattern does not fit between two subsequent vertices. The PolylineGeneration (PLINEGEN) system variable addresses this problem: when set to 1 or ON, the linetype is drawn from one endof the polyline to the other end, instead of from vertex to vertex.

The same polyline drawn with PLINEGEN on (left) and off (right).

Dimensioning Concepts

In BricsCAD there are five dimension types: linear, angular, radial, diametric and ordinate.Dimensions are created by either selecting an entity or by identifying the origin points of the extension lines.

1. Stacked baseline dimension

2. Radial dimension

3. Angular dimension

4. Aligned linear dimension

5. Ordinate dimension

6. Center mark

7. Vertical linear dimension

8. Diametric dimension

9. Rotated linear dimension

10. Leader with text

11. Horizontal linear dimension

12. Arc length dimension

Dimension Style

Dimensions are created on the current layer, using the current dimension style, which controls the appearance of thedimension block. A dimension style is a collection of settings and definitions which determine the type of arrowheads,text style, color of text, lines and arrowheads, unit type, precision, etc. You can modify a dimension by editing one of thedimension settings or you can modify the dimension style to apply the changes to all dimension entities that arecreated with this style. A drawing contains at least one dimension style.

Dimension Block

A dimension entity is created as block, which consists of the dimension line, arrow heads, extension lines and the

Entity Snaps

Commands: 2DINTERSECTION, 3DINTERSECTION, NEAREST, CENTER, ENDPOINT, EXTENSION, FROM,INSERTION, INTERSECTION, MIDPOINT, MTP, NONE, PARALLEL, PERPENDICULAR, POINT, QUADRANT,TANGENT

Entity snaps enable you to quickly select exact geometric points on existing entities without having toknow the exact coordinates of those points. With entity snaps, you can select the end point of a line or arc,the center point of a circle, the intersection of any two entities, or any other geometrically significantposition. You can also use entity snaps to draw entities that are tangent or perpendicular to an existingentity. You can use entity snaps any time you need to specify a point.

You can work with entity snaps in one of two ways

Enable a running entity snap that remains in effect until you turn it off by choosing an entity snapwhen no other command is active.

Enable a one-time entity snap for a single selection by choosing an entity snap when anothercommand is active. You can also use a one-time entity snap to override a running entity snap.

When using entity snaps, the program recognizes only visible entities or visible portions of entities. Youcannot snap to entities on layers that have been turned off or to the blank portions of dashed lines.

If the APBOX system variable is on, the entity Snap Aperture Box is added to the crosshairs when one ormore entity snaps are active.

When you move the cross hairs, the program snaps to the snap point closest to the center of the SnapAperture Box. The Snap Marker indicates the current snap point.

The DRAGSNAP system variable controls the snap behavior while 'dragging', providing an increasedWYSIWIG experience. DRAGSNAP controls whether rubberband dynamics are displayed at the currentcursor location or at the current entity snap location. DRAGSNAP applies to all modify commands thatdisplay dynamics, such as COPY, PASTECLIP, PASTEBLOCK, MOVE, ROTATE, MIRROR, SCALE and STRETCH.

DRAGSNAP = 0 (Default),:dragged entities display at the cursor location.

DRAGSNAP = 1: dragged entities display at the current entity snap location.

NOTE Press the TAB key, without moving the mouse, to cycle through all possible entity snaps.

If the DYNMODE variable has a positive value (Dynamic Dimensions switched ON) entity snapcycling is not possible. Click the DYNMODE field in the Status Bar to toggle the display ofdynamic dimensions.

To define the Entity Snap settings

1. Open the Settings dialog.

2. In the Settings dialog, expand the Program Options settings class.

3. Under Program Options expand the Display settings group, then scroll down to the Entity Snapsettings.

Under Drawing expand the Drafting settings group then go to Coordinate Input > Entity Snaps.

4. Define the Entity Snap settings.

www.bricsys.com/bricscad/help/en_US/V13/UsrGui/source/03_Drawing_Accurately/03_01_Coordinate_Input.htm#Cartesian_coord… 1/4


Coordinate Input

When you create entities in a drawing, they are located in relation to the drawing's underlying Cartesian coordinatesystem. Every drawing has a fixed coordinate system called the World Coordinate System (WCS).

You can also define arbitrary coordinate systems located anywhere in threedimensional space. These are called usercoordinate systems (UCS) and can be located anywhere in the WCS and oriented in any direction.

To specify points and distances using the keyboard you can use the following formats:

Cartesian coordinates: x,y,z

Cylindrical coordinates: R<alpha,z

Spherical coordinates: R<alpha<beta

If you place the @character in front of the entry, the coordinates are calculated with respect to the previous point. Thistechnique is called: Relative Coordinates.

Working with Cartesian coordinates

In the Cartesian coordinate system we use three perpendicular axes: the xaxis, the yaxis and the zaxis. All axesoriginate in the origin point of the coordinate system. The xaxis and the yaxis define a horizontal plane, while the xaxis and the zaxis and the yaxis and the zaxis define vertical planes. A point is defined by its distances to the yz, xzand xy planes. These distances are called the xyzcoordinates of a point.



If you want to enter the absolute Cartesian coordinates of a point, type the x, y and z coordinates separated bycommas: 45.5,57.3,60

If you omit the zcoordinate, the point is placed in the xyplane (Z = 0).

If you place the @character in front of the entry (@x,y), the coordinates are calculated with respect to the previouspoint. This technique is called Relative Cartesian coordinates.

Using relative Cartesian coordinates to draw a rectangle

1. Launch the RECTANGLE command.

2. Specify the first corner of the rectangle.

3. In the command bar type: @<width>,<height>

<width> = the width of the rectangle in drawing units, measured along the xaxis

<height> = the height of the rectangle in drawing units, measured along the yaxis

Go to top

Working with cylindrical coordinates

In a cylindrical coordinate system we use three perpendicular axes: the xaxis, the yaxis and the zaxis. All axesoriginate in the origin point of the coordinate system. The xaxis and the yaxis define a horizontal plane, while the xaxis and the zaxis and the yaxis and the zaxis define vertical planes.

A point is defined using the following format: R<alpha, z.

R = distance to the origin in the xyplane



<alpha = the angle between R and the xaxis (positive angles are measured counter clockwise)

z = the height above the xyplane.

If the zcoordinate is omitted, cylindrical coordinates are referred to as polar coordinates.

If you place the @character in front of the entry, the coordinates are calculated with respect to the previous point. Thistechnique is called Relative Cylindrical coordinates.

Working with spherical coordinates

In a cylindrical coordinate system we use three perpendicular axes: the xaxis, the yaxis and the zaxis. All axesoriginate in the origin point of the coordinate system. The xaxis and the yaxis define a horizontal plane, while the xaxis and the zaxis and the yaxis and the zaxis define vertical planes.

A point is defined using the following format: R<alpha<beta

R = distance from the origin

<alpha = angle in the xyplane (positive angles are measured counter clockwise)

<beta = angle measured from the xyplane (positive angles are measured counter clockwise, above the xyplane)

06/12/13 Inserting Blocks

www.bricsys.com/bricscad/help/en_US/V14/UsrGui/source/12_Blocks_Attributes_External_References/01_Blocks/12_01_02_Inserti… 1/6


Inserting Blocks

Commands: INSERT, INSERT, INSERTALIGNED and MINSERTThe Insert command lets you insert blocks through a dialog box.The Insert command inserts blocks by prompting in the command bar. BricsCAD will lookup the block name in the block definitions inthe current drawing. If the block is not found in the current drawing, the paths defined by the SRCHPATH system variable aresearched. If the block is not found there either, BricsCAD responds 'Could not find file <blockname>'

The Insertaligned command inserts a block entity, with easy alignment on existing entities. The Insertaligned command is similar tothe Insert command, but during the placement the block will be dynamically aligned with existing lines, polylines, arcs or circles. Theblock is aligned with the entity to which the cursor snaps. If no entity is snapped, the block is aligned with the Xaxis of the WCS.

The Minsert command Inserts a block as a rectangular array; combines the Insert and Array commands (short for "multipleinsertion").

You can choose to select an existing block definition or to insert an entire drawing as a block. When you insert a drawing, a new blockdefinition is created in the current drawing. If you change the original drawing file, those changes have no effect on the currentdrawing unless you redefine the block by reinserting the changed drawing. When a block is inserted in a drawing, it is treated as asingle entity.

General procedure to insert a block:

Specify a block definition or drawing file.

Specify the insertion point.

Specify the scale.

Specify the rotation angle.

NOTES When inserting a drawing as a block, the base point, as defined by the INSBASE system variable, of the inserteddrawing is the origin point of the block. The INSBASE system variable is set by the BASE command.If a block contains attributes you will be prompted to fill out the text for each attribute in the command bar.

If the DRAGOPEN system variable is set to zero (OFF), drawings can be inserted as a block by dragging them fromthe Windows Explorer dialog into the current drawing; if DRAGOPEN = 1 (ON), the drawing will be opened instead.The INSUNITS system variable defines a drawing units value for automatic scaling when inserting blocks or

attaching Xrefs (see scheme below).

INSUNITS in the target drawing

INSUNITSin the source drawing Centimeters Inches

not specified(INSUNITSDEFTARGET

= Centimeters)

Millimeters

Inches

not specified(INSUNITSDEFSOURCE



= Inches)

The Unit field under Block Unit is set by the INSUNITS (Insertion Units) settings variable in the source drawing. The Factor fieldexpresses the relation between the value of the INSUNITS variable in the source drawing and the target drawing. E.g. if INSUNITSis Millimeters in the source drawing and Centimeters in the target drawing, the value of the Factor field is 0.1. The Scale factor of theblock is 1,1,1.

If INSUNITS in the source drawing is Unspecified (unitless), INSUNITSDEFSOURCE is used. The value of the Factor field is 1.0 andthe Scale factor of the block expresses the relation between INSUNITSDEFSOURCE and INSUNITS in the target drawing.If INSUNITS in the target drawing is Unspecified (unitless), INSUNITSDEFTARGET is used. The value of the Factor field is 1.0 andthe Scale factor of the block expresses the relation between INSUNITS in the source drawing and INSUNITSDEFTARGET.If INSUNITS is unspecified (unitless) in both the source and the target drawing, INSUNITSDEFSOURCE and INSUNITSDEFTARGET are used. The value of the Factor field is 1.0 and the Scale factor of the block expresses the relationbetween INSUNITSDEFSOURCE and INSUNITSDEFTARGET.The values of INSUNITSDEFSOURCE and INSUNITSDEFTARGET are saved in the registry and therefore apply to all drawings inwhich INSUNITS is unspecified (unitless).

To insert a block


Click the Insert Block... tool button ( ) on the Insert toolbar.Choose Insert Block... in the Insert menu.Type insert in the command bar, then press Enter.

The Inserts dialog opens.

2. In the Inserts dialog, do one of the following:Select an existing block definition in the Name list.Click the Browse button and select a drawing file.

3. (option) Check the Explode option to explode the block after insertion.

4. (option) Uncheck the Specify OnScreen option, then specify the Insertion Point by keying in the coordinates in the X, Y and Zfields.

5. (option) Uncheck the Specify OnScreen option, then specify the Scale by keying in the scaling factors in the X, Y and Z fields.Check the Uniform Scale option to equal the X, Y and Z scale factors.

6. (option) Check the Specify OnScreen option to specify the Rotation angle when inserting the block.



7. Click the OK button.The command bar reads: Insertion point for block.A prompt menu displays.

7. To insert a block, do one of the following:

Click the Insert Block button ( ) on the Details toolbar.When in Icon View, double click the thumbnail image of the block.



When in Detail view, double click the number in front of the block name.

The Drawing Explorer dialog closes temporarily to let you insert the block in the drawing.The command bar reads: Multiple blocks/<Insertion point for block>:

A prompt menu displays

5. Follow the instructions in the command bar to insert the block.The Drawing Explorer window reopens.

6. (option) Insert more blocks.

7. Close the Drawing Explorer Blocks window.

To insert a block aligned with an entity

1. Make sure the appropriate Entity Snaps are active.

2. Type insertaligned or insal in the command bar, then press Enter.The command bar reads: ? to list blocks in drawing/~ to open the file dialog/<Block to insert> <name>:


Press Enter or right click to insert the most recently placed block again.

Type the name of an existing block definition in the command bar, then press Enter.

3. Snap to an entity.The block is aligned with the entity.

4. Click to define the insertion point.When you move the crosshairs, the block is mirrored about the selected entity or a about a line tangent to the selected entity.

5. Click to specify the mirroring of the block.

NOTE If you type the name of block in step 3, BricsCAD will lookup the block in the block definitions in the current drawing. Ifthe block is not found in the current drawing, the paths defined by the SRCHPATH system variable are searched. If theblock is not found there either, BricsCAD responds 'Could not find file <blockname>'

NOTE The block is aligned as follows: The block is rotated so that its local Zaxis is parallel with the Zaxis of the active UCS,and its local Xaxis should be parallel with the tangent to the entity at the position of the snap point. When you click apoint on an entity the block is aligned with the entity. Then, by moving the mouse pointer around the insertion point, youcan choose how the block should be mirrored. The origin point of the block lies on the entity.

To insert multiple instances of a block in a rectangular array

1. Type minsert in the command bar, then press Enter.The command bar reads:



? to list blocks in drawing/~ to open the file dialog/<Block to insert>:


Type ~ (press and hold the Alt gr key, then press the ~ key), then press Enter.The Insert Block file dialog displays.Select the drawing file you want to insert and press the Open button (or double click the file name).Press Enter to accept the <Block to insert>.

Type a rotation angle, then press Enter.

Click to define the rotation angle graphically.The command bar reads: Number of rows in the array <1>:

8. Type the number of rows, then press Enter or press Enter for one row.The command bar reads: Number of columns <1>:

9. Type the number of columns, then press Enter or press Enter for one column.The command bar reads: Vertical distance between rows, or spacing rectangle:

10. Type the row spacing distance, then press Enter.The command bar reads: Horizontal distance between columns:

11. Type the column spacing distance, then press Enter.The block array is created as a single entity.

NOTES If you choose Multiple blocks in step 3, you are prompted to create multiple instances of the block array.It is not possible to explode a MInsert Block entity..If you type the name of block in step 2, BricsCAD will lookup the block in the block definitions in the current

drawing. If the block is not found in the current drawing, the paths defined by the SRCHPATH system variable aresearched. If the block is not found there either, BricsCAD responds 'Could not find file <blockname>'

Redefining Blocks

Commands: BLOCK, BLOCK and INSERTTo redefine a block that was created in the current drawing, you create a new block using the same name.

If the block was inserted from a separate drawing, reinsert that block.

When a block definition is redefined all instances of that block in the current drawing are updated automatically.

See also: Editing blocks and external references.

To redefine an internal block definition

1. Type block in the command bar, then press Enter.The command bar reads: Name for new block, or ? to list existing blocks:

2. Type the name of the block in the command bar and press Enter.The command bar reads: The block <name> already exists. Do you want to redefine it? <N>.A prompt menu displays.

3. To redefine the block definition, do one of the following:

Type Y, then press Enter.Choose YesRedefine block in the prompt menu.

The command bar reads: Insertion point for new block:

4. Specify the insertion point of the new block.The command bar reads: Select entities for block.

5. Select the entities for the new block.

6. Right click to create the block.The selected entities are removed from the drawing.All existing instances of the block are updated.

7. (option) To bring back the selected block entities, type oops in the command bar, then press Enter.

To reload an external drawing as a block


Click the Insert Block... tool button ( ) on the Draw toolbar.Choose Insert Block... in the Draw menu.Type insert in the command bar, then press Enter.

06/12/13 Defining Attributes

www.bricsys.com/bricscad/help/en_US/V13/UsrGui/source/12_Blocks_Attributes_External_References/02_Attributes/12_02_01_Def… 1/3


Defining Attributes

Command: ATTDEF and ATTDEFThe Attdef command defines how a block's attributes will be created through a dialog box.The Attdef command creates block's attribute definitions at the command prompt.

General procedure to define attributes:

specify the characteristics of the attribute, including its name, prompt, and default value;

specify the location

define the text formatting

optionally: set the attribute flags (hidden, fixed, validate or predefined).

To define an attribute


Click the Define Attributes... tool button () on the Tools toolbar.Choose Define Attributes... in the Tools menu.Type attdef in the command bar, then press Enter.

The Define Attribute dialog opens.

2. Define the Attribute:

Type a name in the Tag field.The Tag Identifies each occurrence of an attribute in the drawing. The name you type in the Tag field can beany combination of characters except spaces. Lowercase letters are automatically converted to uppercase.



Type a prompt in the Prompt field.The attribute prompt displays when you insert a block containing the attribute. If a prompt is omitted, the Tag isused as the prompt instead.


Type a default value in the Default text field.For variable attributes, the default value is replaced by the actual value when you insert a block containingthe attribute.

Click the Insert Field button ( ) to assign a field value to the attribute (see Using sheet set and sheetproperties in a title block).

If the Multiple lines flag is checked, the Default text field is dimmed.

Click the button next to the Default text field.The Define Attribute dialog temporarily closes to let you create a Mtext entity.


Specify the x, y, and zcoordinates for the attribute insertion point.

Click the Pick Point button ( ) to specify the insertion point in the drawing.The command bar reads: Select insertion point.The Define Attribute dialog closes temporarily.

(option) Set the Invisible attribute flag.Attributes with the Invisible flag set do not display nor print.If the ATTMODE (Attribute Display Mode) variable is set to 2, all attributes display, including Hidden attributes.(option) Set the Constant attribute flag.Attributes with the Constant flag set cannot be edited.(option) Set the Verify attribute flag.Attributes with the Verify flag set must be explicitly validated when a block containing such attributes isinserted.

(option) Set the Preset attribute flag.When inserting a block you are not prompted to define attributes of which the Preset flag is set. You can editattribute afterwards though.

(option) Set the Lock Position attribute flag to lock the position of the attribute within the block reference.Unlocked attributes can be moved relative to the rest of the block using grip editing and multiline attributes canbe resized.

Define the Text properties: Text Style, Justification, Text height and Rotation.

3. Click the OK button to create the attribute in the drawing.The Define Attribute dialog closes.

4. (option) Right click to reopen the Define Attribute dialog, then repeat steps 2 and 3 to create another attribute.

Using sheet set properties in a title block

1. Create the sheet set.

2. Define the custom sheet set and sheet properties.

3. Open a sheet (layout) from the sheet set.

4. Create the title block source entities in the paper space layout:

Create the borders, line work and fixed texts.

Create attributes with fields that refer to sheet set, subset and sheet properties (see To define an attribute).

See the SHEETSET command to learn more about default and custom sheet set, subset and sheetproperties.

Custom sheet set properties:



Sheet properties and sheet custom properties:

5. Create a block from the title block source entities.

6. Copy the block to drawing in one of your block folders (see To insert a block form another drawing).

7. Delete the title block source entities.

8. The title block can be inserted in the other sheets of the sheet set and in any other sheet set where the samecustom sheet set and sheet properties exist. All fields that refer to default or custom sheet set, subset or sheetproperties are filled out automatically. If no value is available, a field displays hyphens () (see also Placingblocks with attributes).
