As a user since 2013 I am a huge fan and would like to make a suggestion to the development team. Points for holes should have the color-coding for constraints like lines. Currently, points always appear black, no matter if they are constrained or not. We had a project that had some holes that appeared to be in-line with each other. They were constrained horizontally but were not fully constrained vertically. As a result the holes were .033'' off from where they should have been. I am not blaming Alibre for this. We should have caught it. But it would have stood out more if the points were color coded.
