I have an issue that I've been dealing with for a long time. It seems intermittent, but once the problem arrives it stays for a while.
I often mate things to the midpoint of other things. However sometimes when I pick the midpoint it includes the edge. See below. If I delete the edge from the Selected entities by highlighting it in the box and deleting it it does not give me the mate options it just shows the selected entities. See the second pic. It does return the mates if I go back to the graphics area and deselect the line that way.
This is very odd because on several occasions I've had this problem. Been disrupted, came back, and it no longer does this. It only selects the midpoint.
My question is two fold. First is something I'm doing causing it to select the edge and the midpoint. What causes it to decide to pick both or just one? Second is there a way to get rid of the edge and retain and get back to the mate without going back to the graphics window and deselecting it?
