Autodesk.Revit.DB.HostObject

roofOrFloor

The roof or floor.

Return Value IList<HostObjectSubcomponentInfo> A collection of computed components.

Autodesk.Revit.Exceptions.ArgumentException

The host object roofOrFloor must be a floor or a non face-based roof.
Autodesk.Revit.Exceptions.ArgumentNullException

A non-optional argument was null
Autodesk.Revit.Exceptions.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.
