Navigate to the folder to select the model you want to open.
Important: Revit models are not backwards-compatible. When you create or modify a model using the current release of the software, you cannot open the model later using a previous release.
- On Revit Home, under Models, click Open.
As an alternative, from the ribbon, click File tab
Open
(Project).
- In the Open dialog, navigate to the folder where the model resides.
- To see only files of a certain type, select that type from the Files of type drop-down list.
- Select the desired option(s):
- Audit: Scans, detects, and fixes corrupt elements in the model. This option can greatly increase the time required to open models.
- Select the model, and click Open.
In the Preview pane, the dialog displays the Revit LT release that was last used to save the file.
