I work for a Telecom company and we have a lot of maps for our exchanges. We are trying to consolidate them. The problem I'm running in to is getting all the different maps to come in to my new main drawing where they should. Some drawings come in correctly(I'm querrying the dwg's in to the main dwg) and some don't. I'm fairly green in the AutoCAD department, all of my previoius experience is with ESRI products. Also I don't know how these drawings were created as they were done prior to my employment. I've tried assigning the same coordinate system to the drawings and they still come in incorrectly.
I would also like to thank JeramiahM for aswering my imagery question. Now I know what to watch for.
