Hi Peter,
Interesting. This seems to be a problem with the generation of the geometry,
not the meshing.
Attached is the .brep file of the buggy surface (debugSurface.brep):
- the OpenCASCADE representation is wrong (see attached picture of the
OpenCASCADE-produced STL triangulation), which
Right, I have "sew faces" active, which kills the volume

No, the problem is that Gmsh does import the volume
No, the problem is that Gmsh does import the volume but after it you
ask it to perform either one or more of the OCC "healing" procedures and for
some reason these procedures remove the volume.
See if you have something like
Geometry.OCCFixDegenerated
Geometry.OCCFixSmallEdges
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.
