Hello William,
That behavior occurs when you're using RS274D outputs.
To have the gerbers aligned with the drills, use RS274X. Later versions of
CAM350 should load them.

[PCB_FORUM] artwork and drill/netlist alignement
Hello all.
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.

PS. I wrote a little SKILL routine that reports ANTIPAD and REGULAR NULL
definition for vias/pads used in the board.
They are reported as database DRC (eXternally Determined Violation).
If someone is interested...
