Launch the program from ribbon/Add-In tab or using command TL3DPl2AP.

Pick a 3D polyline object. An alignment and a corresponding profile will be generated.

The program will not ask the user for alignment/profile styles or label sets. The first available style definitions in the drawing will be used.

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.

You may need to restart the Autodesk product to activate the app/plug-in.

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 7/8.1/10/11) and uninstall as you would any other application from your system.

The generated alignment and profile are NOT dynamically linked to the original 3D polyline object.

Subsequent changes to the polyline object will not be reflected in the alignment/profile geometry.
