Because of the fact that the Fill Hole command doesn't create an exact circle with a defined center, sometimes it's pretty hard to e.g. make joints at the centers of circles created by the Fill Hole command. It'd be nice if there were automatically a center point that was able to be selected/used as reference after the Fill Hole command is used for e.g. making joints. I've been making do by creating construction axes between points and creating points at the intersection of those axes.
