I'm modeling an object to print with a 3D printer. I'm working with a UV sphere and I've removed some bands at the top and the bottom half. What matters, in terms of size, is the band at the top, the one with all the vertices selected in this photo:
The height and diameter at the bottom either don't matter or aren't as important. How can I easily and quickly check the diameter of this one band at the top of the object? I do not want to just use a measure tool, since it can be hard to get a precise measurement with it. Since I'll be resizing, then checking, then resizing until I get it just right, I would really like to find a way to do this quickly and with minimal steps.
