To unhide a category in Revit, you'll need to use the Visibility/Graphics Overrides dialog. Here's a step-by-step guide:
-
Access the Visibility/Graphics Overrides Dialog: Go to the View tab in the Revit ribbon. In the Graphics panel, click on Visibility/Graphics. Alternatively, you can use the keyboard shortcut VG or VV.
-
Navigate to the appropriate tab: Depending on where the category was hidden, ensure you're in the correct tab:
- Model Categories: For architectural, structural, or mechanical elements.
- Annotation Categories: For tags, dimensions, and other annotation elements.
- Analytical Model Categories: For elements related to structural analysis.
- Imported Categories: For elements imported from CAD or other formats.
- Filters: If the visibility is controlled by filters.
-
Locate the Category: Scroll through the list of categories to find the one you want to unhide. You can use the search bar at the top of the dialog to quickly find a specific category.
-
Restore Visibility: Once you've found the category, check the box in the Visibility column next to the category name. This will make the category visible again in the current view. If subcategories are hidden, expand the main category to find and uncheck them as well.
-
Apply and OK: Click Apply to see the changes in the view. If the category is now visible as desired, click OK to close the dialog.
Troubleshooting:
- View Templates: If the category remains hidden, check if a View Template is applied to the view. If so, the visibility settings in the View Template are overriding the view's individual settings. Edit the View Template to unhide the category there.
- Filters: Sometimes categories are hidden by a filter applied to the view. Check the Filters tab in the Visibility/Graphics Overrides dialog to see if any filters are active and overriding the visibility of the category.
- Worksets: If using worksets, ensure the workset containing the category is open and visible.
By following these steps, you can easily unhide categories in Revit and control the visibility of elements in your project views.
