well that would have been a nice fix, but I have the vector box checked, at least the one under preferneces under snapshot.
I opened up 6 drawing sets, in 5 of them i could snap images and they were transparenet, in one set they are opaque.
of the five sets that were transparent, 3 were made in autocad and 2 in revit, the set that has opaque images was made in revit.
so no pattern
is there another dialoque box or menu that you can switch from pixels to vectors>
