When you import or link a file to a Revit project, you may not want all of the file’s layers to be visible in Revit. To control the visibility of layers, you can do either of the following:
- Hide layers: When you hide layers, they are still available to the project, but they do not display in views. You can make them visible again as needed.
- Delete layers: When you delete layers, they are not available to the project. (However, they still exist in the original CAD file.) If you want to restore the layers, you must delete the file and either import or link it to the project again.
