Steve, I haven't seen your particular problem, but have encountered something similar. It may be that PADS RS274X output isn't correctly interpreted by your viewer . Our viewer (cam350) has an occasional problem with RS274X. Try outputting in RS274D format just to find out. Good luck, Gary Bauder PWB Design Supervisor Amtech Systems Corp. ################################################################ DesignerCouncil E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE DesignerCouncil <your full name> To unsubscribe: SIGNOFF DesignerCouncil ################################################################ Please visit IPC web site (http://jefry.ipc.org/forum.htm) for additional information.
