Is it possible to extend the curved face of the solid, straight up to the new not curved face.
It need to be a solid
Solved! Go to Solution.
Are you aware the corners will cross over before you get to that surface?
Do you have the original geometry from which the Base was created?
Delete the existing 3D sketch (not sure what its purpose is). Create a new sketch on the flat surface, project the perimeter of the curved surface, then extrude to next. It makes a rather odd-looking part, because the lower section has a significant draft, the upper part doesn't.
