to modify this object when it is set to "IsReadOnly" will throw a NotSupportedException.

Gets a values indicating whether a surface is solid.
(Inherited from Surface.)

UserDictionary 
Dictionary of custom information attached to this class. The dictionary is actually user
data provided as an easy to use sharable set of information.

in a Brep, then this function returns the component index.

(Inherited from CommonObject.)  
CreateThroughBox(Plane, BoundingBox)

Duplicate 
Constructs a deep (full) copy of this object.
(Inherited from GeometryBase.)  
DuplicateShallow 
Constructs a light copy of this object. By "light", it is meant that the same
underlying data is used until something is done to attempt to change it. For example,
you could have a shallow copy of a very heavy mesh object and the same underlying
data will be used when doing things like inspecting the number of faces on the mesh.
If you modify the location of one of the mesh vertices, the shallow copy will create
a full duplicate of the underlying mesh data and the shallow copy will become a
deep copy.
