Search for a derivative, tangent, or curvature discontinuity in a curve object.
Rhino.CurveDiscontinuity (strObject, intType, dblAngleTolerance])
strObject 
Required. String. The object's identifier. 

intStyle 
Required. Number. The type of continuity to test for. The types of continuity are as follows:


dblAngleTolerance 
Optional. Number. The angle tolerance in degrees. If omitted, Rhino's internal angle tolerance of 1.0 degrees is used. The minimum allowable angle tolerance is 0.1 degrees. 
Array 
An array of 3D points where the curve is discontinuous if successful. 
Null 
If not successful, or on error. 
Dim strObject, arrPoints
strObject = Rhino.GetObject("Select a curve", 4)
If Rhino.IsCurve(strObject) Then
arrPoints = Rhino.CurveDiscontinuity(strObject, 2)
If IsArray(arrPoints) Then
Rhino.AddPoints arrPoints
End If
End If
