I admit to quickly throwing it together but, I did read through a few instructions and felt I had enough of a handle on it to make a start.
When doing it, I had no problems and saw no errors. In fact, aside from the hole diameters, it worked well in CommperCam (CC) - no big red box… nothing to indicate errors and I wasn’t concerned about the hole diam’s as I always set them to my preferred dim in CC.
Here’s a screenshot of it in CC.
When I saw the post citing the problems, I opened the file and was surprised to see the problems.
Perhaps I’ll try it again but only to feel I’m not too old to learn… But, for practical use, grabbing (as a group of items) the pins/holes from a file of parts I regularly use is fast and mindless…
