Import a DWG or DXF into Autodesk® Revit® that contains line data.

Locate the 3D Lines to the Duct ribbon panel and click the icon to start the app.

You will be prompted to select a DWG or DXF import instance from your active document.

When you select the desired import instance the app will allow you to choose the duct system type, duct shape, and size, and the level to add the duct system before processing the line data.

The app will create new ducts on the selected layer with a center point that exactly matches the lines and polylines in your original import instance.

The installer that ran when you downloaded this app/plug-in from Autodesk App Store will start installing the app/plug-in. OR, simply double-click the downloaded installer to install the app/plugin. To uninstall this plug-in, exit the Autodesk product if you are currently running it, simply rerun the installer, and select the "Uninstall" button. OR, click Control Panel > Programs > Programs and Features (Windows 7/8.1/10) and uninstall as you would any other application from your system.

It does not work with Revit Family files (RFA). Currently, duct joins need to be added manually, but the automation of that process may be added in future releases.
