Hi After making a drawing and extrutions in Pro-E Wildfire 3.0, i want to make an mirrored copy of the part. I thought the solution was simply mirroring the part by choosing all sketches and extrutions in the menu and mirror it about a new plane, then delete the original, but it seems like the copy is grouped in some way to the original, so when deleting the original, the copy also deletes. Can anyone please help me solve this problem? Thanks MB
