Parameters

NumPoints

Specifies the number of points in the curve.

PointTypeConstants

Value	Description
igCylinderEndPoint
igCylinderStartPoint
igKeyPoint
igSpacePoint

Specifies whether the points are keypoints or free space points for each point in the curve.

EdgeSet

Specifies the edges that contain the keypoints on the curve that define the order of points in the curve.

KeyPointTypeConstants

Value	Description
igKeyPointCallback	Keypoint Type - Callback
igKeyPointCenter	Keypoint Type - Center
igKeyPointEnd	Keypoint Type - End
igKeyPointHorizontalSilhouette	Keypoint Type - Horizontal Silhouette
igKeyPointInteriorNode	Keypoint Type - Interior Node
igKeyPointInteriorPole	Keypoint Type - Interior Pole
igKeyPointMajorAxis	Keypoint Type - Major Axis
igKeyPointMiddle	Keypoint Type - Middle
igKeyPointMinorAxis	Keypoint Type - Minor Axis
igKeyPointNonDefining	Keypoint Type - Non-defining
igKeyPointPointOnly	Keypoint Type - Point Only
igKeyPointStart	Keypoint Type - Start
igKeyPointVerticalSilhouette	Keypoint Type - Vertical Silhouette

Specifies the keypoint type for each keypoint in the curve.

Array

Specifies the positions of free space points in the curve.

StartpointEndType

Value	Description
seKeypointEndConditionCurvatureContinuous	Keypoint End Condition - Curvature Continuous
seKeypointEndConditionNatural	Keypoint End Condition - Natural
seKeypointEndConditionNormalToFace	Keypoint End Condition - Normal To Face
seKeypointEndConditionPeriodic	Keypoint End Condition - Periodic
seKeypointEndConditionTangent	Keypoint End Condition - Tangent

Specifies the relationship of the start point to the rest of the curve and surrounding geometry.

EndpointEndType

A member of the KeypointEndConditionConstants constant set that specifies the relationship of the end point to the rest of the curve and surrounding geometry.

Remarks

This method adds a KeyPointCurve object to the referenced KeyPointCurves collection. The KeyPointCurve object can contain a mix of keypoints and free space points.
