Add a definition to be reused by instances. A definition is a single geometry object.

Add a definition to be reused by instances. A definition is a collection of geometry objects.

Add a definition to be reused by instances. Adding a definition type will change how the instances are created. When asked to create a definition, the library object will look for a corresponding type object. If one is found, it will create an instance of geometry stored in the type object. If it is not found, the library will look for a list of geometry objects stored as definition, and will copy and transform these to create an instance.

A quick check whether a definition already exists in the library. Checks for stored geometry objects only.

A quick check whether a definition type already exists in the library. Checks for type objects only.

Releases all resources used by the DirectShapeLibrary

Determines whether the specified Object is equal to the current Object .

Find a definition by id

Find a DirectShapeType element by definition id. The element will be used for creating instances of that definition.

Get the currently active Library object

Serves as a hash function for a particular type.

Gets the Type of the current instance.

Removes all definitions from library. This is useful when importing several self-contained data sets within one session. Once a data set is imported, keeping the definitions specific to that data set will slow down the searches.

Returns a string that represents the current object.

Specifies whether the .NET object represents a valid Revit entity.
