To add a building component to a project, download its ADSK file from the manufacturer, open it in Revit, and load it into a project.
The following steps describe a typical workflow for using a building component in a Revit project. For example, suppose a manufacturer published the contents of a rooftop HVAC unit to its website as an ADSK file to be used by engineers and architects. You want to incorporate this building component in your model. Using the component's geometry and data, you can properly place the component in the project and also create connectors on it, so the component can be used in Revit building systems.
The following procedure describes a typical workflow. Specific steps may vary slightly, depending on your design intent.
