Parameters

roofOrFloor
Type: Autodesk.Revit.DB..::..HostObject
The roof or floor.

Return Value

A collection of computed components.

Exceptions

ExceptionCondition
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.
