The plugin creates a rack with gear with straight, helical, double helical, herringbone and arc teeth for various sets of parameters. The program lets to choose a system of modules, dimensioning of modules, units and much more. Parameters and descriptions of functions are available in Guide.pdf. Information about invoices is available in Consulting Services section (please click More to expand the section).

The attached video shows how to use the plugin and how to create a complex example that requires a few designs.
Execution in most cases takes less than a half minute on i7/8GB RAM/512GB SSD computer.

Disclaimer
The plugin doesn't check interferences automatically and doesn't perform any analysis of prepared components. Please make sure that the necessary check is done before releasing this onto production. You must be aware that the real dimensions of manufactured components may be different than in the design. Every material has different characteristics and its parameters may change during time depending on the kind of material, temperature and humidity of the environment, workload, etc. The simplest motion analysis can be done by using joints and motion rules prepared by the plugin. Both involute and trochoid interferences can be checked by eyes but there’s a better, dedicated built-in tool (TOOLS  Interference) available in Autodesk® Fusion®.
