I tried duplicating then using the flip command as per your suggestion, but it made no difference. the item duplicated is still not a mirror image and it still spins on its center point as I rotate my camera around the assembly room. Today I purchased Ray Dream 5.5 on eBay and may end up having to use it for this kind of modeling. I'm disappointed that Eovia has not addressed this issue. It seems to be a bug that needs to be fixed. In reality, I liked RDS 5.5's interface better and wished they had expended their energy on including a decent patches/nurbs modeler and the ability to rotoscope an image into modeler to work from (ala Animation Master or LightWave) than all the interface eyecandy.
