Description

Constructs a Multipoint consisting of the endpoints of the Curve and the points along the length of the curve spaced a given distance apart from each other starting at the curve's From point and ending at the To point.

Remarks

If the final inner point is too close to the To point, that inner point is not included in the constructed multipoint.
