Create a chamfer in V5 with VB

[dbwalters]

Hello, I am trying to create a chamfer via VB and have been running into a problem using a BRep function:

            Set myRef = myPart.CreateReferenceFromName("")
            
            Set myChamfer = myShapeFactory.AddNewChamfer(myRef, catTangencyChamfer, catTwoLengthChamfer, catNoReverseChamfer, 1.53924, 2.9972)

            padName = myPad.Name     'previously created
            circleName = "GSM" + myHSCircleCtrRad.Name     'previously created
            planeName = "GSM" + myHSPlnTan.Name     'previously created
            
            Set myNextRef = myPart.CreateReferenceFromBRepName("REdge:(Edge:(Face:(Brp:(padName;2);None:();Cf11:());Face:(Brp:(padName;0:(Brp:(circleName;(Brp:(planeName)))));None:();Cf11:());None:(Limits1:();Limits2:());Cf11:());WithTemporaryBody;WithoutBuildError;WithSelectingFeatureSupport;MFBRepVersion_CXR15)", myPad)
            myChamfer.AddElementToChamfer myNextRef
            myChamfer.Mode = catTwoLengthChamfer
            myChamfer.Propagation = catTangencyChamfer
            myChamfer.Orientation = catNoReverseChamfer
            
            myPart.Update

I am able to previously create the a plane, the circle on the plane for the pad, and the pad itself. But, for some reason I am unable to chamfer the pad. Any help would be appreciated. Thanks in advance.
