I have several windows in a drawing and the window endcap is the same as the wall endcap. The wall endcap looks fine. The opening endcap looks fine in the plan view, but in 3-D views, and in sections, there appears to be two sets of endcaps, with one set in line with the wall as normal. But the other endcap shows up beside the wall, in this case, inside the room. Does anybody have any idea what is going on?
