When you import or link a file to a Revit project, you can query the file for information about its objects.
This allows you to determine the identity of an object and the layer on which it resides. You can also hide the object’s layer or delete it.
When you highlight the import symbol, the status bar displays the following:
<imported file name> : Import Symbol : location <Shared> or <Not Shared>.
Revit highlights lower-level objects (such as lines) first. Press Tab to switch to highlighting of higher-level objects, such as blocks.
The Import Instance Query dialog opens and displays the following information:
The selected layer may still be visible in other views.
The selected layer is no longer visible in any project views.
The query editor remains active so that you can select other entities.
