How to do a simple task?

While on the subject of coding... I have updated the Blender S file Exporter to properly support Blender 5.x. With the Help of Codex.

Still BETA, but available... https://github.com/pwillard/Blender_...ases/tag/5.0.0

In case you were looking for an actual answer...

1. You could use the slice plane, make a slice in the appropriate location, and then delete everything you don't need. Slice plane is in the "edit geometry" section of the command panel (below the bevel, extrude, et c. tools) when you have selected either the "polygon" or "element" subobject. Remember to convert to Editable Poly before slice planing. Editable mesh treats the mesh as a game does, i.e. it treats each polygon as a mesh of triangular faces, and will slice those triangles, creating extra verts and triangles you don't need.

2. You could perform a boolean operation with an appropriate intersecting object.

Option 1 is going to be much, much simpler.

Sadly, a lot of us have forgotten what little we knew about the older cad tools we once used.
