# CDSL Bridge: Axisymmetric Revolve

- Choose a closed half-profile and an explicit `axis` for `revolve_add` or `revolve_cut`.
- Use 360 degrees for a complete body. Keep the profile on one valid side of the axis.
- Prefer revolve for steps, shoulders, tapers, grooves, sleeves, and turned parts; use circle extrusion for a constant cylinder.
- Validate one coherent solid and shared axis before adding non-axisymmetric cuts.
