Allow user to draw an arc from given points or edges.
If the user selects points, s-CAD should draw an arc (a partial circle) with variable number of sides. Let the user select the angle to draw this arc (along XY. YZ, or XZ plane, or other plane given by the inference engine.)
If the user selects parallel edges, s_CAd can draw a partial cylinder.
