Q - question

Why the MESHSPIN command complains about the object type?

A - answer The function "Spin Triangle Face" (MESHSPIN) works only with 3D objects of the type Mesh, composed from triangular faces. In these neighbouring faces you can swap their common edge.

On a meshed regular object composed from quad faces you can use the command MESHSPLIT with the Vertex option to create triangular faces.
