The node has two modes, Radius and Points. ``` ``` ``` ``` ``` ```Inputs ``` ```====== ``` ``` ``` ```Resolution ``` ``` Number of edges on the arc. ``` ``` ``` ```Radius ``` ``` The radius of the arc. *Radius* mode only. ``` ``` ``` ```Start Angle ``` ``` Starting angle of the arc. *Radius* mode only. ``` ``` ``` ```Sweep Angle ``` ``` Length of the arc. *Radius* mode only. ``` ``` ``` ```Connect Center ``` ``` Connect the arc at the center. ``` ``` ``` ```Invert Arc ``` ``` Invert and draw opposite arc. ``` ``` ``` ```Start, Middle, End ``` ``` The three points on the arc. *Points* mode only. ``` ``` The order of the points determines the direction (clockwise or counterclockwise) of the arc. ``` ``` The arc will always draw from Start to End via the Middle point. This can be changed by using ``` ``` the Invert Arc option. ``` ``` ``` ```Offset Angle ``` ``` Offset angle of the arc. *Points* mode only. ``` ``` ``` ```.. note:: ``` ``` ``` ``` Because of the finite resolution, the middle point does not necessarily lie on the generated arc. ``` ``` ``` ``` ``` ```Properties ``` ```========== ``` ``` ``` ```Mode ``` ``` :Points: ``` ``` The position and radius of the arc are determined by three points. ``` ``` The center of the arc, radius and normal are also given as outputs. ``` ``` :Radius: ``` ``` The arc is determined by the radius, start angle and sweep angle. ``` ``` ``` ``` ``` ```Outputs ``` ```======= ``` ``` ``` ```Curve ``` ``` Poly spline generated from the inputs. ``` ``` ``` ```Center ``` ``` The center of the arc described by the three points. *Points* mode only. ``` ```Normal ``` ``` The normal direction of the plane described by the three points, ``` ``` pointing towards the positive Z axis. *Points* mode only. ``` ```Radius ``` ``` The radius of the arc described by the three points. *Points* mode only. ```
