Two Revit categories are designed to support construction modeling workflows.
- Parts. You can divide a model element into discrete parts that can be independently scheduled, tagged, filtered, and exported. You can also divide a part into smaller parts. Parts are automatically updated to reflect any changes to the element from which they are derived. Modifying a part has no effect on the original element.
- Assemblies. You can select any number of element instances to create an assembly. The elements in the assembly can then be manipulated as a single unit. Each unique assembly represents a separate assembly type, and you can place instances of that type in the model as needed. Changes to assemblies are tracked as the model changes, and the types are automatically created or updated as needed.
Assemblies can be edited, tagged, scheduled, and filtered. After creating an assembly, you can select an instance of it and generate a sheet and assembly views. The assembly views are listed under the assembly type in the Project Browser and can be dragged onto assembly sheet views as needed.
