Returns a point on the curve at a specified length from the start of the curve. This function is used when you know the length, and need the location. Use arcLengthCurve() if you know the point and need the length along the curve.
curvePointAtLength ( Curve As Part, _
len As Number ) As Point
| Argument | Type | Description |
|---|---|---|
| Curve | part | The curve on which the point will be computed. Must be a kind of curveMixin. |
| len | number | The length from the start of the curve to the result point. |
Intent >curvePointAtLength(Arc_1, Arc_1.radius) --> Point_(2.702, 4.207, 0.0, WorldFrame())
The point returned is precisely one radian around the arc.
Intent >curvePointAtLength(polyLine_1, 10) --> Point_(6.608, -0.411, 0.0, WorldFrame())
The length is measured along each segment.
