TechDraw API
Queste funzioni sono parte del modulo TechDraw e, dopo che il modulo TechDraw è stato importato, possono essere utilizzate negli script e nelle macro o dall'interprete Python.
Good examples of basic TechDraw scripting can be found in the unit test scripts.
See the TechDrawGui API for more functions.
Esempio:
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])Description: Crea polilinee dai bordi in ingresso tramite grafici planari trasversali. Opzionalmente si può escludere la OuterWire impostando il parametro opzionale su falso.
Returns: Elenco dei wire ordinati per dimensione (decrescente)
findOuterWire(listOfEdges)Description: Trova l'OuterWire (più grande) in un elenco di bordi (che formano un grafo planare).
Returns: Outer wire
findShapeOutline(TopoShape, scale, direction)Description: Proietta la forma nella direzione e trova il wire esterno nel risultato.
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(DrawPage, FileName)Description: Save the DrawPage in Dxf.
Returns: File
Example:
import TechDraw
TechDraw.writeDXFPage(myPage,myFileName)
