“Exception while processing, not enough memory available.” (FreeCAD 0.18, Windows)
The model file itself is small, but there must be something wrong with it. Did you create it with some other program?
EDIT: the file itself points to “steptools. com”. It’s of course possible that the model is valid but KiCad and FreeCAD can’t process it. I’m sure Maui will say something more about this…
I was suggesting to check your SolidWorks exporting options.
Anyway you should rise an issue both at launchpad for kicad2step code and at FreeCAD forum attaching the file.
Your model is readable by i.e. CadAssistant of OpenCascades, so both sw shoul handle it correctly.
