TechDraw API

From FreeCAD Documentation

These functions are part of the TechDraw module and can be used in scripts and macros or from the python interpreter, once the TechDraw module has been imported. Good examples of basic TechDraw scripting can be found in the unit test scripts.

See the TechDrawGui module API for more functions.

Example:

import FreeCAD
import TechDraw
page = FreeCAD.ActiveDocument.addObject('TechDraw::DrawPage','Page')
FreeCAD.ActiveDocument.addObject('TechDraw::DrawSVGTemplate','Template')
FreeCAD.ActiveDocument.Template.Template = templateFileSpec
FreeCAD.ActiveDocument.Page.Template = FreeCAD.ActiveDocument.Template
page.ViewObject.show()
view = FreeCAD.ActiveDocument.addObject('TechDraw::DrawViewPart','View')
rc = page.addView(view)


EdgeWalker(listOfEdges, [bool])

Returns: Outer wire

findShapeOutline(TopoShape, scale, direction)

Description: Project shape in direction and find outer wire of result.

Returns: Outline wire

viewPartAsDxf(DrawViewPart)

Description: Return the edges of a DrawViewPart in Dxf format.

Returns: String

Example

fileSpecDxf = "fcOut.dxf"
v = App.ActiveDocument.View
s = TechDraw.viewPartAsDxf(v)
dxfEnd = "0\nEOF\n"
dxfFile = open(fileSpecDxf, "w")
dxfFile.write(s)
dxfFile.write(dxfEnd)
dxfFile.close()
viewPartAsSvg(DrawViewPart)

Description: Return the edges of a DrawViewPart in Svg format.

Returns: String

Example

fileSpecSvg = "fcOut.svg"
v = App.ActiveDocument.View
s = TechDraw.viewPartAsSvg(v)
head = '<svg\n' + \
       '	xmlns="http://www.w3.org/2000/svg" version="1.1" \n' + \
       '	xmlns:freecad="http://www.freecadweb.org/wiki/index.php?title=Svg_Namespace">\n'
tail = '\n</svg>'
svgFile = open(fileSpecSvg, "w")
svgFile.write(head)
svgFile.write(s)
svgFile.write(tail)
svgFile.close()
writeDXFView(DrawViewPart, FileName)

Description: Save the DrawViewPart in Dxf.

Returns: File

Example

import TechDraw
TechDraw.writeDXFView(myPart,myFileName)
writeDXFPage(DrawPagePart, FileName)

Description: Save the DrawPage in Dxf.

Returns: File
