I am using 9.5.2 on MAc OS 9.2.2. I have been using VW for years and do mostly 2D. I recently drew a theatre w/ drapes and a lighting grid using hybrid symbols, walls, and some 3D objects. The walls are one layer, the drape another and the grid another. When I look at the drawing in side view it looks great. When I switch to a front elevation I can see thru the wall to the drape behind. I tried layer linking to a separate layer, different renderings, and putting the wall and drape on same layer. There is nothing the manual that I can find. Any suggestions?
