Disclaimer
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 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 environment, workload, etc. 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 better, dedicated built-in tool (TOOLS  Interference) available in Autodesk® Fusion 360™.
