Duct Fitting Table Viewer

Duct Fitting Table Viewer

Autodesk, Inc.



Autodesk® Revit® MEP utilizes the ASHRAE (American Society of Heating Refrigeration and Air Conditioning Engineers) Duct Fitting Database to lookup coefficients that are used for determining pressure losses through duct fittings. This add-in provides a way to view the illustrations and the data table of available duct fittings from the database. Presently, the ASHRAE Table property of a fitting presents the user a list of tables that may apply to the selected fitting. This allows the user to select a table used for the coefficient lookup.

The Duct Fitting Table Viewer add-in provides the following functionality:

 (1) Visualization of the selected fitting – when a fitting is selected in the add-in, the graphics describing the application of the coefficient table is shown to the user.

(2) Display of the coefficient table – by clicking on the Show Table button, the user can see the lookup table that Revit utilizes for the selected fitting.

(3) Table assignment for multiple fittings at once – allows the user to select multiple similar fittings, and assign them the same table in one operation.

This plug-in was written by Martin Schmid of Autodesk's AEC Industry Success team. It was first published as an ADN Plugin of the Month: http://labs.autodesk.com/utilities/ADN_plugins. The plugin has been provided with the complete source code needed to build the application, with the intention of encouraging users of Autodesk software to use programming to tailor the products they use to their specific business needs.

    Will this be updated for future versions?

    Gopinath Taget | February 18, 2014

    There was a change in Revit 2014 that made a 2013 to 2014 direct port not possible. There’s no replacement currently. Apologies if this is bad news.

    Saves me the trouble of having to pull out the ASHRAE book. Any chance of this being updated for 2014?

    It still works (partially) with 2014. You can copy all the addin files over to the 2014 folder (it installs everything in the user profile). Unfortunately when you pick a fitting and then start the tool, it will not find the part in the list like it does in 2013, so it is a bit limited in its use.

    As Gopi wrote earlier, the change in the main product made it incompatible with 2014 and later version. In 2015 R2 and subsequent releases, however, there is now a graphical table selection option in the core product.
