GetArc

Description

Procedure GetArc returns the start and sweep angle of the referenced arc or round wall.

PROCEDURE GetArc(
				h               : HANDLE;
				VAR startAngleR : REAL;
				VAR arcAngleR   : REAL);

def vs.GetArc(h):
    return (startAngleR, arcAngleR)

Parameters

Name	Type	Description
h	HANDLE	Handle to arc.
startAngleR	REAL	Returns start angle of arc.
arcAngleR	REAL	Returns sweep angle of arc.

Remarks

On round walls, this call won't detect if the wall is reversed or not (should return the inverse of the angle, if the wall is reversed).

Examples

VectorScript

PROCEDURE GetArcSetArcExample;
VAR
h :HANDLE;
startAng, sweepAng :REAL;
BEGIN
h := FSActLayer;
GetArc(h, startAng, sweepAng);
SetArc(h, startAng, sweepAng + 10);
END;
RUN(GetArcSetArcExample);

Python

def GetArcSetArcExample():
	h = vs.FSActLayer()
	if h != None:
		startAng, sweepAng = vs.GetArc(h)
		vs.SetArc(h, startAng, sweepAng + 10)
