I highly agree with Doug on using SNAP as an error checking mechanism, and even
more with using rotated (and named) UCSes aligned with building axes as a way to
align your coordinate systems to a new local point. I've worked on relatively
simple plans with over 10 named UCSes.
I also use the PLAN (current UCS) command option a LOT. That rotates your view
to the correct orientation which makes drafting and dimensioning MUCH more
comfortable.
If you standrdize on a naming system (I used simple numbers, e.g. 1, 2, 3, 4...)
you can build a toolbar of UCS Restore -> PLAN command presets which will zap
you to the correct orientation.
Also, in my years of experience, I've never seen anyone draw a floor plan
accurately with SNAP disabled as a matter of course. Looking in closely at the
geometry always reveals tons of user input errors.
