Control point on circumference of a circle

[AndyW]

Has anyone tried to keep the control point on the circumference of a circle. I want to be able to move my control point around the edge of my circle.

Not at my computer, vaguely remembering trying this a few years ago.  Recall using ang360, but issue is at the 4 cardinal points because of double value responses. 

More recently, JuneTheSecond, did a post about constant linelength shape.  That basically does same thing that you want to do.  Believe it was in User Submitted Section.

JuneTheSecond had another post, which I cannot find at the moment.  Nonetheless, I'm attaching his visio file.  This isn't exactly what you want, it uses a 2nd shape's control point to snap to 1st shape and trace the outline.  Might give you an idea.

Enjoy!
