Thank you for taking the time to look at it and providing valuable feedback.
Interesting…, as follows: First, recognize the values in the Inspector/Advanced panel mean nothing with respect to what I did (since I can’t find info to address changing that and, it’s probably a left-over from using a Pin header as a basis for the part. Meaning that, though it say’s hole size = 1mm, my design is 2mm.
Also, this was not, as you probably suspect, not intended to be a real part but an educational part.
Regarding the hole size:
In Inkscape, I set the parameters to result in Hole size of 2mm. Correct. and verifies using the Grid scale&Grid lines.
Importing gerber into CopperCam_ results in hole size of 2mm with Pad size of 5mm. Correct.
In Fritzing, using the mouse pointer, placing it at pad bottom and pad top (and scrnshot of info) shows a delta of ~5mm, Correct. The delta for the hole in the pads show a PinHole diam of ~2mm, correct.
The math: 0.0787 (25.4) = 2mm, correct.
The layer ID/name: I agree they should be as required. “Required” is the problem - inconsistent info and old age. I looked at several part files (xml) and came away thinking it didn’t really matter - guess I was wrong and will attend to this next go-around.
You provided great comments and I will work through them.
