In the error message dialog, click Expand to extend the error message dialog and view a tree structure listing the errors and warnings associated with your last action.
To see more information about each error, click the plus sign (+) in the tree structure.
You can select (highlight) an error heading, such as Error 1, and all elements associated with that error are selected in the drawing area. Additionally, you can highlight an element name and only that element is selected in the drawing area. After you highlight the element name, you can click Show, and Revit LT searches views for that element only.
You can select the check box next to an element and delete it by clicking Delete Checked.
To return the error dialog to the normal view, click Collapse.
