Hi Les
I have just layed out some parts but the mirror box’s don’t appear to work with duplicates , they do with copies and  the degress rotation does work  with both I have had to use this  to complete the job I have  tried an ealier version on another pc and the X and Y mirror boxs do work.
Is this a bug  I updated the working version to the latest 3.06 and this now no longer works with duplicates.
This is still a great program even with the odd minor problems
