Hey Seth,

I was able to successfully use OpenCascade 7.1 and export using kicad2step!

Now to find out why…

Hi Thomas-

I located a windows machine to try this.  I suspect that this is an artifact of OpenCascade 7.2.  Can you test with OpenCascade 7.1?  I haven't tracked down exactly what changed in 7.2 but it appears that 7.0 and 7.1 work but 7.2 will require additional work in kicad2step.

Of note, OCCT 6.8 also works but 6.9 (and OCE 0.18, which is based on 6.9) do not work either.  This is due to a compiler optimization but appears to be a different issue than the 7.2 one.

Hello Seth,

I’ve had the opportunity to test this on Windows (MSVC, but I’ve had the same issue with MSYS2).
STEP models work great in the 3D viewer, and in the footprint module editor, just as in OCE.
Unfortunately, I cannot get the STEP export to work. I’ve had a run at using OpenCascade before
and encountered this exact same issue. As an example, I’ve attached an outputted file.
The following output is from the command line kicad2step:

20:31:07: C:\dev\kicad-personal\utils\kicad2step\pcb\oce_utils.cpp: fileType: 163
  * no such file: ''

20:31:07: C:\dev\kicad-personal\utils\kicad2step\pcb\oce_utils.cpp: PCBMODEL::AddComponent: 574
  * no model for filename for ‘’

This repeats for every model. If you have any ideas, I’d be very willing to try them out.

Subject: [Kicad-developers] [PATCH] Allow OpenCASCADE standard edition

​Hi All-

Currently, the build requires the opencascade community edition.  For various reasons, I need to have the current non-community edition of OpenCASCADE installed on my work machine.

The attached patch allows compiling KiCad with either the OpenCASCADE community edition or standard edition.

I've tested on a homebrew-based Mac install as well as Linux but haven't verified MSW, if someone would be willing to test it there, that would be great!  The basic search routines are lightly modified from FreeCAD's logic and keep their LGPL copyright on the CMake file.
