Namespace: Autodesk.Revit.DB Class: CurveLoop

CurveLoop.IsOpen

Method
Description:
Returns whether the curve loop is open or closed, as determined by an internal flag.
Remarks:
Some routines in Revit may set the CurveLoop to be marked "open" or "closed" in spite of the actual geometry of the curves. In these special cases, the CurveLoop class does not require that the CurveLoop is correctly marked.
