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 duplex 1 ¾x1 ¼.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.

See the following image for details

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.
