[Gmsh] R: Slice 3D to get 2D geometry

[Vicini Alessandro]

Ok, the problem is that gmsh does not import a volume from component8.step, only surfaces and lines, so "BoundingBox Volume{v()}"  fails. I need to manually generate the volume after import of the step file, and then the rest of the script works.

Your error report  looks what I get, if the script cannot locate "component8.step" (see below).
 I use Win7-64b-pro and Gmsh 4.5.4.
