axboiler.h

Gets all the points of intersection between the object identified by obRef and the object represented by the IDispatch*pEntity.

Except for the datatype of the first parameter, this function is identical to the overload that takes an object ID parameter.

Parameters	Description
objRef	Input object reference of object for which to check intersections
pEntity	IDispatch* of object to check intersections with
option	Enumerated type indicating whether to extend entities
intPoints	Pointer to VARIANT that will be populated with a SAFEARRAY of doubles (VT_R8)
