I want to get the radius of a circle that is already drawn. I tried the component, circle center but that asks me to draw in the viewport, I want to select a pre-drawn Rhino geometry circle and use it's radius.
Thanks Dirk those all work well good to know. I found yet another way more of hack but also worked. Seems like the cen curve should do this maybe that's bugged or I guess we need to feed it a curve.
