The Gerber data 0,0 is taking from the lower left corner of the database and the NCDrill and IPC Netlist data is taking from the 0,0 of the database. You could always adjust your Left X and Lower Y coordinates under Drawing Parameters to a consistent number on your designs so you always know what the offset should be. Be careful that you don't move the Left X and Lower Y so elements in the lower left fall off the extents because in some cases it will corrupt the design. Just turn everything on to see what to change the numbers to. Sincerely, Michael Catrambone UTStarcom, Inc. Chairman Cadence Designer Network CDNLive!

Does anybody know why artworks have an offset from drills and even the netlist when we load them in cam350? I have already seen it with the excellon files and then I used to align drills to the gerber. But now we are loading an IPC 356A netlist to compare with gerber, and we can see that gerbers also have an offset from it. So the error report is consequent...but false of course... How to make gerber with the same origin than drills and IPC nets? Wishing we won't have something to calculate job by job... Thanks in advance and have a nice end of week.

They are reported as database DRC (eXternally Determined Violation).
