Returns the point (in WCS) along a curve at the distance specified by the user
(vlax-curve-getPointAtDist curve-obj dist)
Arguments
The VLA-object to be measured.
The distance along the curve from the beginning of the curve to the location of the specified point.
Return Values
A 3D point list representing a point on the curve, if successful; otherwise nil.
Examples
Assuming that splineObj points to the spline shown in the example for vlax-curve-getDistAtParam, determine the point at a distance of 1.0 from the beginning of the spline:
(vlax-curve-getPointAtDist splineObj 1.0) (2.24236 2.99005 0.0)
