Returns the parameter of a curve at the specified distance from the beginning of the curve
(vlax-curve-getParamAtDist curve-obj dist)
Arguments
curve-obj
The VLA-object to be measured.
dist
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:
