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

[Vicini Alessandro]

In my case component8.step is correctly read, see the complete log below. But I get those errors anyway...

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.
