Hi,

A Boundary Representation is a superset of a surface. It can contain more than 1 surface and additional trim data.
The Morph operation can only deal with plain surfaces. So you need to decompose the Brep and extract the underlying surface. The sweep operation can potentially yield more than 1 surface.

Thank you for your answer!!
