Brad - Thanks for the feedback on ProE. I'm using Wildfire4.
I think one of the issues with this job is the Shopbotter I am working with is really swamped right now with other customers. He is trying to get me to do some of the upfront work on the dxf (partly to save me some setup $$ - which I don't mind at all) so that he can avoid the time to do the setup work. I just don't have the knowledge or software required to get it done. I may need to see if he can just do the work and charge me for it or find another Shopbotter.
