Shared Parameters

Shared Parameters

Shared Parameters are parameter definitions stored in an external text file. The definitions are identified by a unique identifier generated when the definition is created and can be used in multiple projects.

The main objects associated with shared parameters are:

• DefinitionFile - represents a shared parameters file on disk
• DefinitionGroup - group of shared parameters which are organized into meaningful sets
• ExternalDefinition - represents a shared parameter definition, belongs to a DefinitionGroup
• ExternalDefinitions - supports the creation of new shared parameters definitions
• Binding - binds a parameter definition to one or more categories
• BindingMap - contains all the parameter bindings that exist in the Autodesk Revit project

The following sections describe how to gain access to shared parameter definitions through the Revit Platform API, including how to get a shared parameter definition and bind it to Elements in certain Categories.
