Missing Radial Dimensions

I can't tell you how many times I've been asked to help troubleshoot a problem with missing radial dimensions, it probably happens at least once a year and it seems like I always forget why it is they keep disappearing on people.  Every time it's the same problem, a user goes to dimension the radius of a circlular object or line and nothing shows up, followed by the "none of the created elements are visible..." warning:

This is then usually followed by me checking visibility settings, checking view depths, checking the area in 3D and eventually by me saying, "oh yeah, the center point of the circle is outside of the crop region" I don't know why I always forget this, hopefully writing this will help me remember.
The problem is that if you have the annotation crop region turned on, and if the circle is large enough that it's center point exists outside of the annotation crop region, then the radial dimension also exists partially outside of the annotation crop region, and so it doesn't show up. The solution is just to expand your annotation crop region:

If needed you can then grab the center point's blue dot and stretch it back near the object your dimensioning, but you'll still need to keep your annotation crop region expanded to show the center point or it will disappear again.
