# CDSL Bridge: Mounting Plate

- Use for a mostly uniform plate, base, adapter, fixture, or panel.
- Invariants: a named rectangular/rounded profile, thickness, datum-based holes, and functional cutouts.
- Plan: `extrude_add_blind` base -> `hole_wizard` or cut-hole features -> `pattern_linear`/`pattern_mirror` -> slots and pockets -> late `fillet`/`chamfer` only with selectors.
- Prefer `rectangle`, `rectangle_with_fillets`, or `obround` profiles. Keep edge margins and pitch as named numeric parameters.
- Rectangular hole groups use linear/mirror patterns; never use circular-pattern semantics for a plate.
