+The 3D model configuration of each sprocket can be dynamically retrieved using a preset `Configuration table`.
+The file name of the 3D model containing the `Configuration table` is **`Sprocket ANSI simplex 1½x1.FCStd`**.
+
+To obtain the 3D model of the desidered sprocket, click the spreadsheet `Data` in the Tree View and then select the `Teeth Number` in the property editor. If nothing changes try to `Refresh` the model.

+### Notes for developers
+If you add a row in the `Configuration table` of the `Data` spreadsheet, then add that row in the above table of this `README.md` file, without the first cell.
