The tool does as you say, what i would like is for the start end point to be remembered so when it is edited the arc stays in place, see the picture. Hopefully it is clear. Good to have your feedback it is making it clearer what behavior i would like to see in arc tool. Maybe I'm going long way around to find out.All I know is I dont like to have to go and find the tool each time to redraw an arc when there is one there already which could just be adapted either by dragging directly or by numerical control.
OIC what your saying. Less about drawing it, and more about editing not working with a radius value. Draws the arc, arc shows a radius, but once edited it turns into a curve (Or endpoints grow.)
