I am trying to mirror an assembly that was built and constrained to a sketch. When I do the mirror command, some pieces mirror correctly and others are turned upside down or inside out. I am wondering if this is caused from the original model being contstrained to that sketch? I ask that because the constraints in the mirrored assembly do not appear to be "valid" and nothing is constrained any more.

     is there a way to mirror an assembly without having to go thru every piece and select the "opposite hand" option for the ones that are backwards, upside down,etc. Also, can the sketch be mirrored as well if THAT is what is holding the assembly together?

Thanks in advance,
