boolProp allow45DegreeAngleOfRotation true
* Need to use the "," or the "." keys to rotate ("<" or ">") the object
* Some large (i.e. multi-tile objects) may not visually appear correct at 45 degree angles.
* Should not be used on windows or doors, as they will already snap to diagonal walls.
* No guarantee that sims can interact with all objects that are at this orientation, but most should work.

setHighestAllowedLevel [level]
* The current lot is the one that is affected.
* The level is always greater than the default of 4.
* There is no limit with regards to memory usage, which may lead to game instability.
