ArcTo

Description

Procedure ArcTo creates an arc vertex with a point of intersection at the specified coordinate point.

The endpoints of the arc are tangent to the control segments which intersect at p. If a radius of 0 is passed as the parameter, the arc endpoints will be at the vertices preceding and following the arc spline vertex.

PROCEDURE ArcTo(
				pX,pY          : REAL;
				radiusDistance : REAL);
def vs.ArcTo(p, radiusDistance):
    return None

Parameters

Name Type Description
p REAL Coordinates of vertex.
radiusDistance REAL Radius of vertex arc.
