I have an assembly that is made of 20 or so parts. I need a LH version of the assembly and a RH version. Most of the parts are the same version of the original part (not mirrored, just in a mirrored location or orientation). One or two parts are actually left hand and right hand versions. I have tried mirroring the parts and then suppressing the original parts. When I edit the mirror feature I get a warning that the suppressed parts can't be resolved.
What is best practice to create a LH and RH version of an assembly?
EDIT: To put a finer point on the question. I create a second configuration and mirror all the parts. NOw that the parts are mirrored does one hide the origionals, delete them or what?
