vlax-curve-getEndParam

Returns the parameter of the endpoint of the curve

(vlax-curve-getEndParam curve-obj)

Arguments

curve-obj

The VLA-object to be measured.

Return Values

A real number representing an end parameter, if successful; otherwise nil.

Examples

Assuming that ellipseObj points to the ellipse shown in the example for vlax-curve-getArea, the following function call returns the end parameter of the curve:

_$ (vlax-curve-getendparam
ellipseObj)

6.28319

The end parameter is 6.28319 (twice pi).
