Just done it - and no, no pads. It's definitely a problem within Protel, (but easier to visualise in a gerber viewer which can display pads & tracks in different colours). > If so, it may be easier to get Altium to take a look at the problem, > too - if it can be demonstrated all within Protel. Hmm. I don't even know who to report bugs to at Protel / Altium, or if it's worth the effort. > I have been using this technique to check Protel output, and haven't had > a problem that wen't undetected by Protel. (Except for the giant aperture > definitions in 274X, which my PCB vendor can't handle.) I'm not sure if you import & check your gerbers, looking for features that have been rendered wrongly... It's not something I'm prepared to do. (this board reports as 20,000 tracks, 4019 pads, and I'm looking for a defect 8 thou by 6 - it's quicker to have it etched & assembled than to go through looking for weird problems) (I may also chase the "generate software arcs gives straight lines" issue, which caught me out a while back - the PCB shop swore blind I had thousands of sub-thou gaps - oddly all where teardropping had placed arcs... I just turned off "use software arcs" and all was well, so I let it slip. I'm really not a good software tester...)
