I’m using PADS for layout, just to make things difficult on myself. When I exported using Excellon 2.4 with trailing zero suppression, the DRC bot warned me that my design had no drill hits. So I poked around and found that my drill file looked exactly like the “bad” example from this post:
====
%
T1C.02F197S550
X123456Y123456
[etc]

So, I modified it to look like the “good” example, and disabled any zero suppression, just in case.

Now I don’t get the warning from the DRC bot, but my preview image doesn’t show any drill hits, either:

The large circle in the center is a mounting hole. Notice the lack of hole.
So, should the preview image show drill hits? If so, and mine aren’t showing up, what can I do to fix my drill file?
thanks.
