Offset the vertices of a mesh along their normal directions.

Input parameters:

1. Ms → Mesh to offset.
2. Of → Offset distance. Positive values indicate the offset is in the direction of the normal.
3. So → Specifies whether the offset mesh and the original mesh are stitched together along their naked edges.
   •  True → Solid
   • False → Shell
4. Av → Specifies whether to average the normals along creases prior to offsetting.
   •  True → Average
   • False → Retain

Output parameters:

1. Ms → Mesh with offset vertices.
