I found this "puller" (y-shortcut) to provide a (somewhat perverted) workaround to create an arc of arbitrary angle in the GUI :)

You draw an arc of 90º (let radius be 35mil, in 1st quadrant), but we want 60º. Position cursor at the center of the arc *with keyboard cursor keys*. Disable grid (to not snap cursor to it) with shift-g. Issue command like Cursor('Warp',40.42,0,mil). Here 35/sin(60*pi/180)=40.415. Start drawing a line at that point. Carefully, to not move the mouse. Finish line around the arc. Type y for puller. Delete the line. Get an arc of 60º. Enable grid with g.

It is important to zoom as much as possible because Cursor moves crosshair by rounding *mouse cursor* coordinates.
