I'm doing some work involving Missions, Mission Scenarios and Vignettes. I've also created a hierarchy of mission elements so that the subtypes can inherit the measurement sets added to the main type (i.e., scenario or vignette). When I create an actual scenario or vignette (instance) the slots within the actual measurement set are not visible. Either I'm not using the measurement set properly or I need to create individual measurement properties in the parent to ensure visibility in the actual scenario. Can any one suggest the best way to apply measurement sets.
