Hi Colin, I'll try to add that in.

In the meantime, you can use "Distance constraint" to help out right now.

To do this, just type in your distance and hit enter (you can also click on the "d" text box down on the bottom bar).

Doing that activates distance constraint which forces the point that is being picked to be that distance away from the base point. So for Ellipse/Center that would be 1/2 the width since the base point is the ellipse center point in that case. So you would actually need to enter in half of your desired full width for this one. Still easier than counting grid spaces though.

But I'll try to add in a width/height like rectangle so you won't have to divide in half.
