Glass cut to a shaped outline cannot be ordered from a drawing. It has to be templated from the table itself, after the table is finished.
The reason is accumulation. A shaped edge is worked by hand along its whole length, and the difference between the drawing and the finished timber is a millimetre here and a millimetre there - nothing you would ever see in the wood, and everything you would see as a rim of glass overhanging one side and sitting short on the other.
So the glass is templated last. A sheet of thin board is laid over the finished top and scribed from underneath, following the actual edge all the way round, including every curve. That board becomes the pattern the glass is cut to, and it is cut a controlled amount inside the timber line so the timber edge always protects the glass rather than the other way round.
The template is kept with your order. If the glass is ever broken, a replacement is cut from the original pattern rather than by sending someone to measure a table with a tape - which on a curved edge is guesswork.
It adds a stage to the schedule, because the glass cannot be started until the table is finished. It is the only way a shaped glass top sits as though it grew there.
