Face Match Workflow

1. Left-click one face on the fixed piece, then one face on the moving piece.
2. (Optional) Add edge and vertex constraints by clicking matching edges/vertices.
3. Click Match to compute and play a collision-safe path.
4. If a selection is wrong, click Clear Selection and re-pick.

Tip: face-only matching is the fastest way to test an assembly direction.
