Exceptions

Exception	Condition
ArgumentException	The host object roofOrFloor must be a floor or a non face-based roof.
ArgumentNullException	A non-optional argument was null
InvalidOperationException	The roof or floor cannot be split into subcomponents by this routine. Possible reasons are, among others: (1) the roof or floor contains non-planar surfaces, (2) the roof or floor cannot be divided into sub-components of equal thickness, or (3) the roof subcomponents contain inner boundary loops.
