You didn't specify it, but I'm assuming that you are using CAMtastic from what you write below.
The gerber files I'm trying to see are produced with Mentor by a consultant of mine, that always produced these filse the same way, and I never experienced any problem before.
If this had been a Protel import, it would be more understandable, for Protel was not designed specifically to import generic Gerber but only Protel-generated Gerber, and thus many of the commands used in RS-274X, and which might be used in a different way by other programs, are not correctly interpreted by Protel.
However, it's CAMtastic, which is supposed to be universal, designed to import *all* CAM files.
So I'd really suggest slicing up the gerber until you find the offending Gerber commands. It would be easy to compare these commands with the RS-274X standard. And with Protel and CAMtastic output.
If CAMtastic is failing to read standard RX-274X gerber, Altium should be notified. Anyone know if there is a known bug in CAMtastic regarding this? (We know that Protel won't read much of anything that it has not generated, there are too many variables and the programmers did not try to build a generic gerber import into Protel....)
In effect I suppose that is a Camtastic's import issue: I have previously imported gerber files that I correctly view in an old cam documen, but, if I try to re-import these files with the brand-new-installed DXP, I experience the problem I tried to explain below.
Something is off, for sure. Perhaps there is an option in CAMtastic we don't know about. I don't have an installation handy at the moment to look.
Look at the actual gerber code. It's not hard to read. Google RS-274X to find a manual on the standard.
