Brad,

Just getting the gerber files together for the photo plots. We used to use P-cad Ass. Designers Edition V2.0. The pad master files were never generated in P-cad and I was just wondering if I could merge them or just delete the pad master gerbers. Sounds like I will just delete them. I've kinda been learning this on the fly and doing things the way I was told. Now that we have Protel and I have some breathing room I'm trying to find out why I'm doing things (should have done it a long time ago) Thanks very much for your quick reply, this post will probably get lots more simple or rediqueles posts from me but...

Thanks again,

Jerry Gierach
