Re: Struggling to convert OpenSCAD to STEP
It is an export issue. The V0.20 step is faulty. Attached the V0.19 step file for comparison.

Re: Struggling to convert OpenSCAD to STEP
As Keith has more knowledge of me, his advice is the right one.
From what I had seen some time ago I've seen that in early days you have to had OpenSCAD installed to manage OpenSCAD files so I've wrongly supposed that the solid creation was only the last passage, and following OpenCascade introductions that was recently published on the OpenCascade site the result was a "non parametric solid" so it is a Brep representation of the original OpenSCAD mesh.
Thank you for clarifications @keithsloan and others.

Re: Struggling to convert OpenSCAD to STEP
The OpenSCAD executable is used to create a CSG from a SCAD source, the Workbench importer parses the CSG file and creates BREP shapes. It is only if there are hull, minkowski requests that these need to be converted to meshes/dxf and the OpenSCAD executable is called on to perform the hull, minkowski. The other circumstances where you get meshes is where a STL file is imported. This basically has been the situation since the workbench was introduced in FreeCAD 0.13. Recently @chennes has been sorting out some bugs with extrusions and rotated extrusions etc. He has also developed test cases so hopefully any regressions can be pick uponekk wrote: ↑Mon May 10, 2021 7:49 am As Keith has more knowledge of me, his advice is the right one.
