Parameters

originalPolyline  IEnumerablePointD3D

The original polyline.

westVector  VectorD3D

The west vector at start of the original polyline.

northVector  VectorD3D

The north vector at the start of the original polyline.

forwardVector  VectorD3D

The forward vector at the start of the original polyline.

startIndex  Double

The start index. Must be greater than or equal to zero.

endIndex  Double

The end index Must be greater then the start index and smaller than or equal to originalPolyline.Count-1.

startCapForwardAndPositionProvided  Boolean

If true, position and forward vector of the start cap were already calculated (but not west and north vector).

startCapNeedsJoiningSegment  Boolean

If set to true, there is need for a joining segment between start cap and the rest of the polyline. This joining segment is returned in the enumeration. It has the same position as the start of the returned polyline, but the forward, west and north vectors of the start cap.

startCapCOS  PolylinePointD3DAsClass

Position, forward, west and north vectors of the start cap. This information will be filled in during the enumeration.

endCapForwardAndPositionProvided  Boolean

If true, position and forward vector of the start cap were already calculated (but not west and north vector).

endCapNeedsJoiningSegment  Boolean

If set to true, there is need for a joining segment between the end of the polyline and the end cap. This joining segment is returned in the enumeration. It has the same position as the end of the polyline, but the forward, west and north vectors of the end cap.

endCapCOS  PolylinePointD3DAsClass

Position, forward, west and north vectors of the end cap. This information will be filled in during the enumeration, and will be valid only after the enumeration has finished.
