Ok I tried to do a search, but didn't come up with anything that might pertain to my problem. I have an iges file of a part that after painstakingly getting it through the import diagnosis, I need to mirror it to represent the left hand part. The problem is that I have is that the part is not complete basically I have the surfaces as solid bodies, and just sketches that represent the outline of the part. When I select all of it and insert mirror part, it mirrors the solid body correctly but, the sketch which I also need mirrored it just comes in normal. Please help as this is causing me to pull out my hair!
