splice_mesh_at_z
Splice two STL meshes at a specified Z height, taking the top geometry from one file and the bottom from another. Use it to combine design iterations by merging the best parts of each version.
Instructions
Splice two meshes at a z-plane: top from one STL, bottom from another.
Takes geometry ABOVE *z_plane* from *top_path* and geometry BELOW
*z_plane* from *bottom_path*. Triangles crossing the boundary are
clipped cleanly. No boolean ops -- works on non-manifold meshes.
**Use case:** Combine a body with the correct top (e.g. logo from
v5.3) with a body that has the correct bottom (e.g. larger pocket
from v5.4) to create the next design iteration.
:param top_path: STL providing geometry above z_plane.
:param bottom_path: STL providing geometry below z_plane.
:param z_plane: Z height (mm) where the splice happens.
:param output_path: Output STL path. Auto-generated if empty.
:returns: Dict with splice stats and output path.
