NewReferencePoint creating with two referenceplane

[1368026189]

List<ReferencePlane> listBT = new List<ReferencePlane>();
List<ReferencePlane> listLR = new List<ReferencePlane>();

foreach (ReferencePlane refLR in listLR)
{

  Line lBT = getLineFromRPlan(refBT);

  foreach (ReferencePlane refLR in listLR)
  {
    Line lLR = getLineFromRPlan(refLR);
    XYZ intersectPt = getIntersectPt(lBT, lLR);
   listPts.Add(intersectPt);
   ReferencePoint refPtA = doc.FamilyCreate.NewReferencePoint(intersectPt);

}

if I create a NewReferencePoint like above,The refPoint won't move when my refPlane moves, there is no relationship between them.

 I figured out that the  NewReferencePoint method has a load ReferencePoint NewReferencePoint(PointElementReference ) and  the point will remain constrained to that reference. but I don't know how to construct a PointOnEdgeEdgeIntersection with my refPlane,

Please help me out ,Thanks!

it isn't clear to me what you are trying to achieve, but you make a PointOnEdgeEdgeIntersection like this:

document.Application.Create.NewPointOnEdgeEdgeIntersection(Curve1.Reference, Curve2.Reference);

Thanks FAIR59

Sorry being so late to reply, I get an alternative way by 

doc.FamilyCreate.NewAlignment(viewLeveWMD, curve.GeometryCurve.GetEndPointReference(0), ref1a.Reference)

public Dimension NewAlignment(
View view,
Reference reference1,
Reference reference2
)
