NX has supported smart lightweight capabilities with PRT components, and it’s now supported for JT components. NX smart lightweight capabilities allows users to work with facet data like it was exact data. When required, exact data is loaded automatically. JT smart lightweight saves time by not requiring exact data to be loaded.
Smart lightweight enables the following operations on facet data: selection of bodies/faces/edges, associative measures, assembly constraints, WAVE links, drafting, PMI & color overrides.
