Hi. I want to cut extrude a pattern into a part that has a curved exterior surface. Easy enough. However, I want the extruded pattern to follow the curvature of the part. If I insert a plane tangent to the part and create my sketch on that plane, the resulting cut extrusion obviously is linear. Not the affect I'm after. I can't figure out how to first wrap the sketch on the surface and then cut extrude it. Perhaps I need to create a 3D sketch? Zero experience with that Design tool but if that's how it's done I'll figure it out. Thanks in advance for any enlightenment others can provide.
