I'm trying to wrap (emboss to 1/4" thickness) Sketch4 onto the front, concave face of the attached part. When I attempt to do so, it says "The Wrap feature cannot be created from intersecting or open contours". I've tried removing the middle construction line from the sketch, which didn't work. I also tried Repair Sketch under Sketch tools, but it found no gaps. I've done this type of thing with other sketches successfully, and I can't seem to figure out why I'm getting this problem now. Any ideas?
