Solid Edge Part Type Library
Add3 Method
Solid Edge Part Type Library > KeyPointCurves Collection : Add3 Method
Number of space points for the creation of curve.
This array is to know whether point is space or key point. Constant used for this are:- igKeyPoint, igSpacePoint.
Parent edges for keypoint curve.
This is array of keypoint constants which states type of keypoint i.e. whether it is start,mid point etc .(igKeyPointStart, igKeyPointMid, igKeyPointEnd)
This array consists of position for space points.

This is the kind of end condition required by user at start point. It can be

1.seKeypointEndConditionNatural
2. seKeypointEndConditionTangent
3. seKeypointEndConditionCurvatureContinues
4. seKeypointEndConditionNormalToFace

Face to be used for normal option for start point of curve.
Magnitude of vector at start point
This is the kind of end condition required by user at end point. It can be either
1.seKeypointEndConditionNatural
2.seKeypointEndConditionTangent
3.seKeypointEndConditionCurvatureContinues
4.seKeypointEndConditionNormalToFace
Face to be used for normal option for end point of curve.
