Returns the point at the specified parameter value along a curve
(vlax-curve-getPointAtParam curve-obj param)
Arguments
The VLA-object to be measured.
A number specifying a parameter on the curve.
Return Values
A 3D point list representing a point on the curve, if successful; otherwise nil.
Examples
For the following example, assume that splineObj points to the spline shown in the example for vlax-curve-getDistAtParam.
Obtain the start parameter of the curve:
_$ (setq startSpline (vlax-curve-getStartParam splineObj))
0.0
Obtain the end parameter of the curve:
_$ (setq endSpline (vlax-curve-getEndParam splineObj))
17.1546
Determine the point at the parameter midway along the curve:
_$ (vlax-curve-getPointAtParam splineObj
( / (- endspline startspline) 2))
(6.71386 2.82748 0.0)
