I want to export pcb model to other 3D design software.And somebody say I can export the design to step in pcbnew. File -> Export -> Step.But I didn’t find Step,instead,I found there be File -> Export -> GenCAD.And what GenCAD command can generate is .cad file,but I found no software can open it.
Is my kicad software version is old,so my menu haven’t File -> Export -> Step?And if it really doesn’t exist Step,how can I open .cad file?
