If you receive an error message during the course of your work, the message may report a problem with an element and refer to that element by an ID number. To help you locate that element in your project, you can select it using that ID number. Your support representative may also ask you to find the element using its ID.
To select an element by ID number
Revit locates the element and selects it in the view. This tool is especially useful if you are trying to locate a view-specific element by its ID.
