To Connect Ducts Through Referenced Drawings

Use this procedure to connect duct systems in one drawing with duct systems in referenced drawings.

Note: For more information, see Multi-Floor Duct Systems in Referenced Drawings.
  1. Verify that the xref containing the duct system is loaded in the drawing and that the referenced drawing itself is not open.
  2. Draw a duct run to connect your duct system with the duct system in the reference drawing.
  3. Use the lock elevation icon in the Properties palette to connect the duct run to the reference object at the same elevation as the duct run.

    If you do not lock the elevation, the duct run is likely to connect to a duct end connector on the reference object.

    Tip: Use 2 viewports to get an accurate preview of the routing and connection point with the reference duct.
  4. Click Yes when prompted by the Save to Xref dialog box.
    Note: The changes are permanently saved to the duct in the referenced drawing.
