vlax-curve-getStartPoint

Returns the start point (in WCS) of the curve

(vlax-curve-getStartPoint curve-obj)

Arguments

curve-obj

The VLA-object to be measured.

Return Values

A 3D point list representing the start point, if successful; otherwise nil.

Examples

Get the start point of the ellipse used to demonstrate vlax-curve-getArea:

_$ (vlax-curve-getStartPoint
ellipseObj)

(2.0 2.0 0.0)

For an ellipse, the start points and endpoints are the same.

Obtain the start point of the spline used to demonstrate vlax-curve-getDistAtParam:

_$ (vlax-curve-getStartPoint
splineObj)
