Offset Shell

Status: Implemented

Offset Shell thickens every face of the selected faces' parent solid except the selected faces, then unions the thickened solids into one shelled result.

Inputs

• faces – One or more faces to exclude while shelling the parent solid. All faces must belong to the same solid.
• distance – Signed shell distance. Per-face thickening uses the opposite sign, so 2 thickens by -2 and -3 thickens by 3. Must be non-zero.
• id – Optional identifier applied to the generated shell and its faces.

Behaviour

• Collects the solid from the selected faces; aborts if selections span multiple solids or no solid is found.
• Uses OffsetShellSolid.generate to thicken every non-selected face of the parent solid and boolean-union the results; leaves the original solid untouched.
• Names the result <parentName>_<featureID> and visualizes it for downstream selection.
