Hi,

Not sure if this is a bug or not, but I'm trying to mirror a part in my drawing, and none of the 4 orientations give me the desired result.  The only way to make it work is to select "Create opposite hand version" which creates a new part file, even though it is a simple flat plate (left and right should be exact same part).  I've tried both bounding box center and center of mass options.  Some parts work and some don't.  Any ideas?
