Hi,
before making the request, let me know what you think.

In NX there is the possibility of a Mirror graphic objects.
This could certainly improve performance.
If SolidWorks Corp. would implement SolidWorks, it would beacceptable to decide on which parts make a Mirror graphics and takeaccount of this in the BOM.

If you agree with me, I put the request.

Thank you,
