TechDraw: export View to DXF

[wandererfan]

Looks like __objs__ is a list of DocumentObjects with a Shape property. Need to either give DrawViewPart a Shape property or
make a version of "importDXF.export" that takes raw edges as input.

have you seen @ row 1935 of importDXF.py

Code: Select all

        elif (len(exportList) == 1) and (exportList[0].isDerivedFrom("TechDraw::DrawPage")):
            # page: special hack-export! (see below)
            exportPage(exportList[0],filename)

and later

Code: Select all

def exportPage(page,filename):

it seems there was some WIP

Code: Select all

    elif view.isDerivedFrom("TechDraw::DrawViewDraft"):
        geom = Draft.getDXF(view)
        block,insert,blockcount = getViewBlock(geom,view,blockcount)

Looks like only for DraftView with Svg to Dxf conversion, but I'll look deeper.

Yes, LibreCAD 2.13 compared to LCAD 2.09

How does this file look in 2.13? It was converted by importDXF.export.

This is how it looks in LibreCAD 2.2.0-alpha.

it is perfect!
The good news are that this format is also directly compatible/readable with Adobe products, where the old export was not

Hi,
Are you going to PR this to FC 0.18?

Hi @wanderfan
I realized that I can read a DXF using the new readDXF function.

Code: Select all

import Import
Import.readDXF.__doc__
'readDXF(filename,[document,ignore_errors]): Imports a DXF file into the given document. ignore_errors is True by default.'

What I noticed is that if I use the 'Import.writeDXFObject'

Code: Select all

Import.writeDXFObject.__doc__
'writeDXFObject([objects],filename [,version,usePolyline,optionSource]): Exports DocumentObject(s) to a DXF file.'

I can write DXF also with bsplines... Cool
But If I read back the DXF with Import.readDXF I miss the bsplines...

Could it be possible to add bsplines also on Import.readDXF function?

here a sample
