[OpenSCAD] aligning/flooring all objects

Right - OpenSCAD can't do this for you.

The "trick", really, is to design all your parts around a convenient 
origin and then translate them to the assembled position.  It seems most 
people's intuition is to model the part in the assembled position and 
then try to move it back to a convenient origin for printing (or 
whatever else).

I'm sure some will debate this being a better way, but it's much more 
obviously the best way if you get to a point where you're reusing models 
that you created.  Having a convenient origin makes this *much* more 
practical, for a lot of reasons.
