The plugin creates pairs of cylindrical gears 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 the module, units and much more. Information about invoices is available in Consulting Services section (please click More to expand the section).
Detailed information about parameters is available on this site or in the Guide.pdf document in the plugin’s installation folder (please check the last tab Information to know where the plugin files are located). 

The attached video shows how to use the plugin and how to create a complex example that requires few designs.
Execution in most cases takes less than half of the minute on an i7/8GB RAM/512GB SSD computer. During the operation a progress bar with the current step is visible and the process can be always canceled.
 

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 360™.
