Returns the start parameter on the curve
(vlax-curve-getStartParam curve-obj)
Arguments
The VLA-object to be measured.
Return Values
A real number representing the start parameter, if successful; otherwise nil.
Examples
Assuming that ellipseObj points to the ellipse shown in the example for vlax-curve-getArea, determine the start parameter of the curve:
_$ (vlax-curve-getstartparam ellipseObj)
0.0
The vlax-curve-getEndParam function.
