TypeBinding

Class

Description:
TypeBinding objects are used to bind a property to a Revit type, such as a wall type.

Remarks:
This differs from Instance bindings in that the property is then shared by all instances that use that type. Changing the parameter for one type affects all other instances that use that type.
