Hello,

I'm trying to export my part as step without GUI. For this purpose I want to use Part.export().
Unfortunately I get the following error:

Code: Select all

>>> sono=App.ActiveDocument.getObject("Pad001")
>>> Part.export([sono],"test.step")
      Traceback (most recent call last):
      File "<input>", line 1, in <module>
      RuntimeError: FreeCAD exception thrown (Writing of STEP failed)

Am I doing something wrong or is there a different way to export?

Thanks,
vad

Hi vad, welcome.
There are several topics like https://forum.freecadweb.org/viewtopic.php?t=16295 about this. Forum search may help.

Try:

Code: Select all

sono=App.ActiveDocument.getObject("Pad001")
sono.Shape.exportStep("test.step")

@ chrisb: thank you for your welcome . I searched through several topics but couldn't find the solution for my problem.

@ PrzemoF: thank you for your suggestion. I tried it, but I also get an error:

Code: Select all

sono.Shape.exportStep("test.step")
Traceback (most recent call last):
  File "<input>", line 1, in <module>
Part.OCCError: Writing of STEP failed

Can you upload the file and/or test export on a simple box? It works for me, but I have newer Freecad, but older OCC/Coin

I tried to export via Shape.export() a simple box, but I still get the error.
The export via GUI works fine!?

Maybe try to record macro and see how FreeCAD does the export? But it will be GUI export..
Do you use this?

Code: Select all

import Import

[vad]

Now it works .
I have to write the whole directory of the desired step file.
I tried the three following commands:

Code: Select all

Part.export([testbox],"C:/Users/vad/Desktop/testbox/box.step")

testbox.Shape.exportStep("C:/Users/vad/Desktop/testbox/box.step")

import Import
Import.export([testbox],"C:/Users/vad/Desktop/testbox/box.step")

all of them worked.


Thanks

Import.export, but I can't make it work...

Thank you PrzemoF. I tried it and it works now.
