Merdog,
Yes, we manufacture these parts, to the customers specifications. The parts are not entirely paperless, though. Several specs come with them on how to interpret the model files.
To be able to go paperless, all departments would have to be able to view and interrogate the model files, from design to purchasing, manufacturing and quality control. All record keeping would have to be electronic, as would work instructions, etc. This would entail quite an investment in hardware, software and training.
While it seems a worthwhile goal, you must remember that when CAD was first used on a widespread basis, instead of creating an environment where less paper was used, the opposite occured.
If you only want to eliminate 2D drawings, then with proper organization, investment, and company buy-in, you should be able accomplish it. It helps that your parts are made in house. Having other vendors make them will increase the headaches involved.
I wish I could provide you with more details, but I don't have enough experience in this area to be of much help. I don't see our company going that route for quite some time, if at all.
Maybe someone else here has some advice, or you could try posting questions in the Engineering Configuration Management forum. Good luck and keep us posted!
