kicad step export

[Alihossein Sepahvand]

the work on step export has been really great. I'd like to make the raised pads for FEA to be as large as the thickness of the copper it'self. also I want to make it an option

Also, the vias and pads should be segmented (or as an option) to prevent over-meshing. 

Any objection?

Hey Alihossein,

I think it's ok to add options, just make sure to test fusing on various boards because OCCT's algorithms are not always reliable (also see https://gitlab.com/kicad/code/kicad/-/issues/19251)

Can you explain what you mean by segmentation and why would it prevent over-meshing?

I have implemented this option already and initial tests seems to be okay. I will try to do that with all the demos. thanks for the suggestion. 

When you have a curve, mesh tools try to conform to the curve, therefore, it will result in a finer mesh. In many cases, the mesh fails and you need to spend a lot of time specifying mesh size around those curves.
