I may need your service. Are you familiar with SolidWorks? I have the software but it takes me too long to draw something up, as I'm not completely fluent in it yet. I'm assuming you can send the original .sldprt file afterwards?
I only have a business version for autocad. but its possible to import .sldprt into autocad.
So i can help you with your problem. Just contact me via PM with the explicit details.
