# CDSL Bridge: Slotted Adjustment

- A slot is an obround cut with equal end radii, dimensioned by width, length, and a datum frame.
- Use an `obround` sketch and `extrude_cut_blind`/through-depth after the base exists.
- A slot is not a shaft keyway or revolved groove. Pattern or mirror only after the seed cut is valid.
- Leave material at slot ends and finish slot edges last when selectors are available.
