To Add a Duct Fitting Manually

Add duct fittings other than those specified by you in the Duct Routing Preference.

AutoCAD MEP 2023 toolset adds fittings as you draw a duct run based on default fittings in the Duct Routing Preferences, or you can manually add a fitting to an existing segment or duct run. You can also add a fitting where you want to start a segment or run or customize the connection to a part.

Routing preferences specify the common fittings used for most duct layouts. However, the default duct parts catalog includes many other fittings you can use.

To add a duct fitting manually

1. In the HVAC workspace, to select a fitting, click Home tab Build panel Duct Fitting drop-down Duct Fitting . Find
   Tip: You can also use the Fitting tool palette.
2. On the Properties palette General, click the part image next to Part.
3. In the Select a Part dialog box, select a part from the catalog.
   

   Select a Part dialog box

   Under Select Part from Catalog, the dialog box organizes duct fittings based on shape type.

4. (Optional) Select Display/Hide additional part parameters to expand the contents of the parameters table.
5. Use the filter to sort through the list of parts.
   Note: The part catalogs and content locations determine the parts that you can select.
6. Select a part size.
7. On the Properties palette, under Placement, enter an elevation.
   Note: If you insert a fitting in an existing duct run, you do not need to specify the elevation. The fitting inherits the elevation and system settings from the duct run.
8. Specify an insertion point in the drawing, and use the compass to specify a rotation angle.

   You can use duct curve or end connectors to insert the fitting on an existing duct object.

Note: You can apply turning vanes to duct fittings to reduce pressure loss. In plan view, turning vanes are displayed on fittings as annotation.
