Currently, when a Direct 90-degree Vertical at Wall returns back from the wall on top of the pipe going towards the wall, the pipe on top hides the underneath pipe. A common way of representing this in 2-D models is by adding a "jog" in the pipe. However, in the isometric model the jog doesn't need to appear because overlapping isn't a problem. Automatically showing this "jog" on the 2-D model would make representing these cases much easier.
