Face selection when changing the colour is a PAIN!, - if one by chance selects one single vertex or edge the RMB click does not show Properties, what's the logic behind that??? you select 50 faces and one edge everything has to be reselected! BAD BAD! - select the faces in window / cross window? Selection in Inventor behaves in different ways, why not one simple single way?: need to add to selection, JUST CLICK to select, need to deselect- press ctrl or shift. Now sometimes can just click to select or you have to ctrl to add to selection. Make it one single way. as simple as possible!
