MikeInside's Internal Modular Stairs Tutorial

You should be careful using it because it sometimes tends to screw up your walls... In other words, the tops of the walls can sometimes end up jagged in order to remain parallel with the floor. Someone I knew had a lot of trouble with this 'til she finally figured it out. I don't know how she solved it, though. I haven't even tried this cheat yet, but I plan to. I intend to build everything else first, though, and then fiddle with the elevation (and hope it doesn't do the same to me).

The best way to use this cheat, is to save at every point you make an adjustment. Because sometimes using the 'undo tool', doesn't always undo a jagged wall.
Then you must see if the upper levels are affected as well. Sometimes if you are working and only have the lower floor in view, the jagged wall can be affected on the above levels only. So if you wish to save yourself a lot of time, SAVE after each positive adjustment.
