# Chain Sprockets ISO606 duplex 1 3/4" x 1 1/4" from z 8 to z 40

This folder contains the 3D models of the sprockets for ISO 606 chains duplex 1 3/4" x 1 1/4" with number of teeth ranging from z=8 to z=40.

The model is parametric and the values are contained in the spreadsheet `Data`.
The parameters refer to the sprocket dimensions as in the drawing below:

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.
