Transformation of a Cylinderical Surface To a Planar Surface


I need to project a cylindrical surface onto a planar surface. I think projecting radial wire to edge with BRepProj_Projection and reconstructing face with it may be a solution. However if some other features were on the cylindrical surface (signatures etc.) I want to project them too to a surface.

This is a case of projecting bended surfaces. Do you have any ideas and what can I do in such cases?

Thanks in advance...
