to add import and export LCS within STP files?
Yes, I have. The STEP Axis information is part of the GD&T section. I did some research on how various other CAD handles this. I think FC is almost a blank in this area at the moment. Someone did a GD&T workbench some while ago based on Draft dimension, but was abandoned. And based on the look of the code, I decided not to continue the work. Instead, I plan to add basic GD&T support directly in Part workbench, maybe based on the existing Part measurement, to make them editable object and so on. But that is likely going to wait till the next release.

That is fine then.
I was thinking to add the LCS support as a first feature, but I can understand you would prefer to implement all GD&T in one go, having a better overview of the all problem.

Thanks a lot for your improvements in STEP import/export code... Links are just great when assembling a PCB from KiCAD to FreeCAD! The file size of STEP is getting optimized too.

Looking forward to see your branch merged!
:D
