Windchill Options and Variants supports multi level configurable product, so that configurable module can contain configurable module. Configurable modules at Windchill can be collapsible.
This level of functionality is not really implemented at Creo Parametric Options Modeller. In Options Modeller one must stick with onle level of Configurable modules. This will lead to CAD structure, where Configurable Product Variant just lists selected modules (parts, assemblies) in flat manner. For a complex product, this will result additional challange to locate and model products in CAD.
Enhance Options Modeller to support multi level configurable modules.
