Forgive my probably dumb question as I am still learning the volume type data.

My end goal is to create a volume object from a pointcloud and export it as a solid for cad. I suspected this had to be easy but it might be harder than I anticipated.

What I did was feed the pointcloud to a TinGenerator and I got an acceptable surface, which I can apparently not symply extrude. This is all I want, an extruded surface with a thickness of 1 meter.

I found the BRepSolidBoundaryCreator.Beta on the hub but it needs python 2.7 which I didn't install last time apparently.

Do I want something impossible or am I missing the obvious?

Thanks for looking :-)

You should be able to extrude the TIN Triangles coming out of the TINGenerator though.

Hello, you can do it by extruding the surface edge, offsetting the surface and sandwiching together like this. Owen

Thanks for the suggestion Hans, it works great when writing to multipatch but I can't get it to cad, yet. :-)

Ha this sounds like the solution I was looking for @owen, thanks! Will try this next possibility but it looks promising.
