hi all - i'm working on a couple projects with navisworks manage 2014. i can't understand why some of the objects allow me to adjust the transparency, and others do not. most of the time it's the Architectural model that i can't adjust. if i highlight the object and right-click, then go down to transform - transparency, then slide the bar over to about 60%, nothing happens. then i go into the properties of the item, and it has a material property for transparency, which says 0.00. why can't i adjust it within navisworks?
