Everything has been working fine until the other day. I'm trying to print multiple parts and some of the parts aren't showing up in the print preview. Attached in the word doc are screen shots. Kind of weird. any got any ideas?

Thanks

Yes, you not selecting the models that the process gets applied to. At the bottom of the process page there is a button.

Thanks Jimc, I knew is was something stupid . Got another question. Sometimes when I drag and drop part in. It puts it on top of another part.
