Ritnings modulen tillåter dig att lägga ut ditt 3D arbete på papper. Det är, att lägga vyer av dina modeller i ett 2D fönster osh att sätta in det fönstret i en ritning, till exempel ett ark med en ram, en titel och din logotyp och slutligen skriva ut det arket. Ritningsmodulen är för närvarande under konstruktion och är mer eller mindre en teknologisk förhandstitt!

Ritnings modulen tillåter dig att lägga ut ditt 3D arbete på papper. Det är, att lägga vyer av dina modeller i ett 2D fönster osh att sätta in det fönstret i en ritning, till exempel ett ark med en ram, en titel och din logotyp och slutligen skriva ut det arket. Ritningsmodulen är för närvarande under konstruktion och är mer eller mindre en teknologisk förhandstitt!
'''Note'''
The [[Draft Module]] has its own [[Draft_Drawing]] too to place Draft objects on paper. It has a couple of extra capabilities over the standard Drawing tools, and supports specific objects like [[Draft Dimension|Draft dimensions]].

Detta är verktyg för att skapa, konfigurera och exportera 2D ritningsark
I bilden så ser du huvudkoncepten av Ritningsmodulen. Dokumentet innehåller ett formobjekt (Schenkel) som vi vill göra en ritning av. Därför så är en "Sida" skapad. Sidan fås genom en mall, i detta fall "A3_Landskap" mallen. Mallen är ett SVG dokument som kan innehålla din vanliga sidram, din logotyp eller så den överensstämmer med dina presentationsstandarder.


* [[Image:Drawing_New.png|32px]] [[Drawing_Open_SVG|Open scalable vector graphic]]: Opens a drawing sheet previously saved as an SVG file
I denna sida så kan vi sätta in en eller fler vyer. Varje vy har en position på sidan (Egenskaper X,Y), en skalfaktor (Egenskap skala) och ytterligare egenskaper. Varje gång som sidan ,eller vyn, eller det refererade objektet ändras så regenereras sidan och visningen uppdateras.

För tillfället så är arbetsflödet för slutanvändaren väldigt begränsat, så skript API't är intressantare. Här följer exempel på hur man använder skript API't för ritningsmodulen.

=== Simple example ===


* [[Image:Drawing_Openbrowser.png|32px]] [[Drawing_Openbrowser|Open Browser]]: Opens a preview of the current sheet in the browser
First of all you need the Part and the Drawing module:
<syntaxhighlight>
import FreeCAD, Part, Drawing
</syntaxhighlight>
Create a small sample part
<syntaxhighlight>
Part.show(Part.makeBox(100,100,100).cut(Part.makeCylinder(80,100)).cut(Part.makeBox(90,40,100)).cut(Part.makeBox(20,85,100)))
</syntaxhighlight>
Direct projection. The G0 means hard edge, the G1 is tangent continuous.
<syntaxhighlight>
Shape = App.ActiveDocument.Shape.Shape
[visibleG0,visibleG1,hiddenG0,hiddenG1] = Drawing.project(Shape)
print "visible edges:", len(visibleG0.Edges)
print "hidden edges:", len(hiddenG0.Edges)
</syntaxhighlight>
Everything was projected on the Z-plane:
<syntaxhighlight>
print "Bnd Box shape: X=",Shape.BoundBox.XLength," Y=",Shape.BoundBox.YLength," Z=",Shape.BoundBox.ZLength
print "Bnd Box project: X=",visibleG0.BoundBox.XLength," Y=",visibleG0.BoundBox.YLength," Z=",visibleG0.BoundBox.ZLength
</syntaxhighlight>
Different projection vector
<syntaxhighlight>
[visibleG0,visibleG1,hiddenG0,hiddenG1] = Drawing.project(Shape,App.Vector(1,1,1))
</syntaxhighlight>
Project to SVG
<syntaxhighlight>
resultSVG = Drawing.projectToSVG(Shape,App.Vector(1,1,1))
print resultSVG
</syntaxhighlight>
=== The parametric way ===


* [[Image:Drawing_Orthoviews.png|32px]] [[Drawing_Orthoviews|Ortho Views]]: Automatically creates orthographic views of an object on the current drawing sheet
Create the body
<syntaxhighlight>
import FreeCAD
import Part

App.ActiveDocument.Box.Width=100.00
App.ActiveDocument.Box.Height=100.00


* [[Image:Drawing_DraftView.png|32px]] [[Draft_Drawing|Draft View]]: Inserts a special Draft view of the selected object in the current drawing sheet
App.ActiveDocument.addObject("Part::Box","Box1")
App.ActiveDocument.Box1.Length=90.00
App.ActiveDocument.Box1.Width=40.00
App.ActiveDocument.Box1.Height=100.00


* [[Image:Drawing_SpreadsheetView.png|32px]] [[Drawing_SpreadsheetView|Spreadsheet View]]: Inserts a view of a selected spreadsheet in the current drawing sheet
App.ActiveDocument.addObject("Part::Box","Box2")
App.ActiveDocument.Box2.Length=20.00
App.ActiveDocument.Box2.Width=85.00
App.ActiveDocument.Box2.Height=100.00


* [[Image:Drawing_Save.png|32px]] [[Drawing_Save|Save sheet]]: Saves the current sheet as a SVG file

App.ActiveDocument.Cylinder.Angle=360.00
# Fuse two boxes and the cylinder
App.ActiveDocument.addObject("Part::Fuse","Fusion")
App.ActiveDocument.Fusion.Base = App.ActiveDocument.Cylinder
App.ActiveDocument.Fusion.Tool = App.ActiveDocument.Box1


* [[Drawing_ProjectShape|Project Shape]]: Creates a projection of the selected object (Source) in the 3D view.
App.ActiveDocument.addObject("Part::Fuse","Fusion1")
App.ActiveDocument.Fusion1.Base = App.ActiveDocument.Box2
App.ActiveDocument.Fusion1.Tool = App.ActiveDocument.Fusion
# Cut the fused shapes from the first box

Insert a Page object and assign a template
<syntaxhighlight>
App.ActiveDocument.addObject('Drawing::FeaturePage','Page')
App.ActiveDocument.Page.Template = App.getResourceDir()+'Mod/Drawing/Templates/A3_Landscape.svg'
</syntaxhighlight>
Create a view on the "Shape" object, define the position and scale and assign it to a Page
<syntaxhighlight>
App.ActiveDocument.addObject('Drawing::FeatureViewPart','View')
App.ActiveDocument.View.Source = App.ActiveDocument.Shape
App.ActiveDocument.View.Direction = (0.0,0.0,1.0)
App.ActiveDocument.View.X = 10.0
App.ActiveDocument.View.Y = 10.0
App.ActiveDocument.Page.addObject(App.ActiveDocument.View)
</syntaxhighlight>
Create a second view on the same object but this time the view will be rotated by 90 degrees.
<syntaxhighlight>
App.ActiveDocument.addObject('Drawing::FeatureViewPart','ViewRot')
App.ActiveDocument.ViewRot.Source = App.ActiveDocument.Shape
App.ActiveDocument.ViewRot.Direction = (0.0,0.0,1.0)

App.ActiveDocument.ViewRot.Scale = 1.0
App.ActiveDocument.ViewRot.Rotation = 90.0
App.ActiveDocument.Page.addObject(App.ActiveDocument.ViewRot)
</syntaxhighlight>
Create a third view on the same object but with an isometric view direction. The hidden lines are activated too.
<syntaxhighlight>

App.ActiveDocument.ViewIso.Y = 140.0
App.ActiveDocument.ViewIso.ShowHiddenLines = True
App.ActiveDocument.Page.addObject(App.ActiveDocument.ViewIso)
</syntaxhighlight>
Change something and update. The update process changes the view and the page.
<syntaxhighlight>
App.ActiveDocument.View.X = 30.0
App.ActiveDocument.View.Y = 30.0
App.ActiveDocument.View.Scale = 1.5

See the [[Drawing API example]] page for a description of the functions used to create drawing pages and views.
Drawing dimensions an toleranecs are still under development but you can get some basic functionality with a bit of work.


Here a script that can easily fill the [[Macro_CartoucheFC]] leaf FreeCAD A3_Landscape.
First you need to get the gdtsvg python module from here (WARNING: This could be broken at any time!):

FreeCAD kommer med ett standardset med mallar, men du kan hitta fler på [[Drawing templates/sv|Ritningsmallar]] sidan.
To get a feature control frame, try out the following:
<syntaxhighlight>
import gdtsvg as g # Import the module, I like to give it an easy handle
ourFrame = g.ControlFrame("0","0", g.Perpendicularity(), ".5", g.Diameter(), g.ModifyingSymbols("M"), "A",
g.ModifyingSymbols("F"), "B", g.ModifyingSymbols("L"), "C", g.ModifyingSymbols("I"))
</syntaxhighlight>
Here is a good breakdown of the contents of a feature control frame: http://www.cadblog.net/adding-geometric-tolerances.htm


== Extending the Drawing Module ==
The parameters to pass to control frame are:
#X-coordinate in SVG-coordinate system (type string)
#Y-coordinate in SVG-coordinate system (type string)
#The desired geometric characteristic symbol (tuple, svg string as first, width of symbol as second, height of symbol as third)
#The tolerance (type string)
#(optional) The diameter symbol (tuple, svg string as first, width of symbol as second, height of symbol as third)
#(optional) The condition modifying material (tuple, svg string as first, width of symbol as second, height of symbol as third)
#(optional) The first datum (type string)
#(optional) The first datum's modifying condition (tuple, svg string as first, width of symbol as second, height of symbol as third)
#(optional) The second datum (type string)
#(optional) The second datum's modifying condition (tuple, svg string as first, width of symbol as second, height of symbol as third)
#(optional) The third datum (type string)
#(optional) The third datum's material condition (tuple, svg string as first, width of symbol as second, height of symbol as third)


Some notes on the programming side of the drawing module will be added to the [[Drawing Documentation]] page. This is to help quickly understand how the drawing module works, enabling programmers to rapidly start programming for it.
The ControlFrame function returns a type containing (svg string, overall width of control frame, overall height of control frame)'''


== Tutorials ==
To get a dimension, try out the following:
* [[Drawing_tutorial|Drawing tutorial]]
<syntaxhighlight>
import gdtsvg
ourDimension = linearDimension(point1, point2, textpoint, dimensiontext, linestyle=getStyle("visible"),
arrowstyle=getStyle("filled"), textstyle=getStyle("text")
</syntaxhighlight>
Inputs for linear dimension are:
#point1, an (x,y) tuple with svg-coordinates, this is one of the points you would like to dimension between
#point2, an (x,y) tuple with svg-coordinates, this is the second point you would like to dimension between
#textpoint, an (x,y) tuple of svg-coordinates, this is where the text of your dimension will be
#dimensiontext, a string containing the text you want the dimension to say
#linestyle, a string containing svg (i.e. css) styles, using the getStyle function to retrieve a preset string, for styling the how the lines look
#arrowstyle, a string containing svg (i.e. css) styles, using the getStyle function to retrieve a preset string, for styling how the arrows look
#textstyle, a string containing svg (i.e. css) styles, using the getStyle function to retrieve a preset string, for styling how the text looks

With those two, you can proceed as above for displaying them on the drawing page. This module is very buggy and can be broken at any given moment, bug reports are welcome on the github page for now, or contact jcc242 on the forums if you post a bug somewhere else.

Revision as of 06:16, 28 August 2021

Development of the Drawing Workbench stopped in FreeCAD 0.16, and the new TechDraw Workbench aiming to replace it was introduced in v0.17. Both workbenches are still provided in v0.17, but the Drawing Workbench may be removed in future releases.

Introduction

Ritnings modulen tillåter dig att lägga ut ditt 3D arbete på papper. Det är, att lägga vyer av dina modeller i ett 2D fönster osh att sätta in det fönstret i en ritning, till exempel ett ark med en ram, en titel och din logotyp och slutligen skriva ut det arket. Ritningsmodulen är för närvarande under konstruktion och är mer eller mindre en teknologisk förhandstitt!

Gränssnittsverktyg

Detta är verktyg för att skapa, konfigurera och exportera 2D ritningsark

  • Insert a view: Inserts a view of the selected object in the active drawing sheet
  • Annotation: Adds an annotation to the current drawing sheet
  • Clip: Adds a clip group to the current drawing sheet
  • Open Browser: Opens a preview of the current sheet in the browser
  • Ortho Views: Automatically creates orthographic views of an object on the current drawing sheet
  • Symbol: Adds the contents of a SVG file as a symbol on the current drawing sheet
  • Draft View: Inserts a special Draft view of the selected object in the current drawing sheet
  • Spreadsheet View: Inserts a view of a selected spreadsheet in the current drawing sheet
  • Save sheet: Saves the current sheet as a SVG file
  • Project Shape: Creates a projection of the selected object (Source) in the 3D view.

Note The Draft Workbench has its own Draft_Drawing too to place Draft objects on paper. It has a couple of extra capabilities over the standard Drawing tools, and supports specific objects like Draft dimensions.
