Launch the program from the ribbon/Add-Ins tab or using command TLTextAlongCurve.

Select an MText entity and then a curve. Supported curves are Lines, Polylines, Fitted Polylines, Splines, Arcs, Circles, Ellipses, Elliptical Arcs and Polygons.

Fine-tune the end result by adjusting:

 - start position by moving the mouse 

- Text size by pressing Up/Down keys

- Text Spacing by pressing +/- keys

- Text Orientation by pressing the F key

- Character rotation by pressing the R key

The final collection of text characters is combined into a single anonymous group object.

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.

Line curves are handled differently - only some of the adjustment parameters are available in that case, as the text is not broken down into individual characters.

No group is created in that case.

Currently only mtext entities are supported.
