When i started up revit this morning, after about one hour of drawing i wanted to check the materials in the walls and roofing i made,
but after i rendered it nothing showed, just plain white walls, all walls, and the roof has materials in it, pre configured by the support senter i used, and when i check the element properties for all the objects nothing shows up.
what's wrong with my rendering mode ?
worked perfectly yesterday..
