IntersectionEvent Properties 
The IntersectionEvent type exposes the following members.
Name  Description  

IsOverlap 
All curve intersection events are either a single point or an overlap.
 
IsPoint 
All curve intersection events are either a single point or an overlap.
 
OverlapA 
Gets the interval on curve A where the overlap occurs.
If the intersection type is not overlap, this value is meaningless.
 
OverlapB 
Gets the interval on curve B where the overlap occurs.
If the intersection type is not overlap, this value is meaningless.
 
ParameterA 
Gets the parameter on Curve A where the intersection occured.
If the intersection type is overlap, then this will return the
start of the overlap region.
 
ParameterB 
Gets the parameter on Curve B where the intersection occured.
If the intersection type is overlap, then this will return the
start of the overlap region.
 
PointA 
Gets the point on Curve A where the intersection occured.
If the intersection type is overlap, then this will return the
start of the overlap region.
 
PointA2 
Gets the end point of the overlap on Curve A.
If the intersection type is not overlap, this value is meaningless.
 
PointB 
Gets the point on Curve B (or Surface B) where the intersection occured.
If the intersection type is overlap, then this will return the
start of the overlap region.
 
PointB2 
Gets the end point of the overlap on Curve B (or Surface B).
If the intersection type is not overlap, this value is meaningless.
