Arc Node¶

The Arc node generates a poly spline arc. 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.

참고

Because of the finite resolution, the middle point does not necessarily lie on the generated arc.

Mode

포인트:: 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.

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.
