Off the top of my head this is the way I would achieve it:
Since AC does not have simultaneous updates for multiple windows you will have to toggle, but you can reduce it to hitting a single key.
Put Elevations around your work area and place the 4 views on a layout like I showed above.
Draw in plan. To Quickly toggle to Layout with all elevations hit
F7 Elevation will all be in one place and will update.
Toggle back to plan hit
F2
And if you want to toggle to 3D, hit
F3
It would be awesome to have live views in all windows so that you could see your changes instantaneously in plan/elevations/3D but it is not killing me that AC does not have it. And yes, I know r^@#t can do this so no gloating on the other side of the aisle. Using the function keys works well for me. If GS adds live views in the future though I will not complain.
You could also tile your windows and just click between the plan, elevations or layout. The window will update when you click on it.
