Returns the parameter of a curve at the specified distance from the beginning of the curve
(vlax-curve-getParamAtDist curve-obj dist)
Arguments
The VLA-object to be measured.
A number specifying the distance from the beginning of the curve.
Return Values
A real number representing a parameter, if successful; otherwise nil.
Examples
Assuming that splineObj points to the spline shown in the example for vlax-curve-getDistAtParam, determine the parameter at a distance of 1.0 from the beginning of the spline:
_$ (vlax-curve-getParamAtDist splineObj 1.0)
0.685049
