Have drawn house in 3D in several layers all correctly referenced (Z, delta Z) to the ground plane (the only working plane). I've linked relevant layers to a linked layer. However, when I view this linked layer in any 3D mode, most of the walls, especially those with symbols (doors, windows) in them, appear some 61' below the ground plane! These misplaced objects are not layer or class specific. The slabs, site paving and some walls are shown at the correct elevation. I'm stumped.
