Hi Michael and PaQ ...
Thanks for the very rapid replies.
Yes, I can use Rhino but sometimes for printing I would like the image to look just like the screen image in MoI it's better than any of the shaded versions Rhino has (in my opinion) ... but for drawings that need to be printed to scale (or rendered) I guess that Rhino is my best bet
cheers,
eric

PS ... as sidebar; Yesterday I was getting some render/shading artifacts in Rhino that were surfaces not in the drawing. Opening the drawing in MoI and saving the drawing with MoI corrected the problem when reopened in Rhino. I don't know what went on there but thanks, Michael.
