Vendors supply dimensions, depending on where in the world the product 
comes from, could be metric, imperial

or fraction

The vendor is out of the picture at this point. They provide a catalog, 
and we enter (or import) items into our POS system. We match their 
dimension within tolerance.

No. Slabs eg granite, slate, dolemite, marble..cut from larger blocks 
and delivered in blocks of ten slabs normally, where tolerances are 
also  +/- .032

I will say this business has been behind in the attributes game. Plus 
there are many "artsy" vendors

who can hardly speak in these terms, and don't publish to us, so we do 
the best we can.

Getting vendors to supply the basic values is a struggle.
