Windchill Rest API for Configurable parts, option sets with include/exclude/conditional/... rules
We're trying to create a front-end configuration tool based on data in windchill. This data consists of a configurable part with a set of components which have expressions on them. Based on the choices made in the optionset you can 'configure' your new part. To create this front-end we'd like to fetch the configurable part and its BOM, the assigned option set with its options & choices, and the associated include/exclude/conditional/.. rules that go with this option set.
Getting the configurable part is pretty straight forward with the REST services (1.7), but the optionset with options,choices and rules proves more difficult as I can not find the right API endpoints. Can anyone point me in the right direction?
