   When selecting elements, you can use the Filter Assistant to apply a filter based on element types and/or properties. For more information, see Filter Assistant.

   The Filter Assistant helps you select specific elements.

   A message appears informing you of the number of collisions found. After you have confirmed this message, the colliding elements are displayed in the selection color.

4. Check more elements or press ESC to quit the tool.

Notes:

• Elements that are switched off in plan display or that are on frozen layers are ignored.
• The colliding elements are no longer displayed in the selection color when you check for collisions a second time, modify the precast elements or switch to a different drawing file.
