Name	Return Type	Description	Inherited From
C CurveElementFilter(CurveElementType)	None	Constructs a new instance of a filter to match specific types of curve elements.
C CurveElementFilter(CurveElementType, Boolean)	None	Constructs a new instance of a filter to match specific types of curve elements, with the option to match all curves which are not of the given curve type.
