Unfold |
- Ruled (by default): allows you to unfold
a ruled surface only. If the surface is not ruled, an
error message is issued. It computes an exact unfold of
the input surface. The area and lengths of the surface
are kept in the final result.
- All: allows you to unfold any surface. If
the surface is ruled, a warning message is issued
offering you to switch to the Ruled type. It
computes an approximation of the flattened surface. The
area and lengths of the input surface may differ from
the area and lengths of the unfolded elements.
