drafting for glass work

I have some books on drafting, e.g. Technical Drawing by Giesecke, Mitchell and Spencer. They seem to be primarily oriented towards metal work, with some attention given to woodworking and less to building construction, landscaping and airplane design. On pp.491-496, the book I mentioned above has a section entitled "Analyzing the Job", where they show how to pass from a shop drawing to a detailed list of procedures to be followed for each part. The list is called a "job analysis sheet".

I don't know whether such lists are ever made for glass working, nor what kinds of shop drawings are used for glass work. If so, are there some books that describe them and give some examples?

Normally, drawing or drafting for stained glass work, where it is most common (as opposed to hot glass work, where artistic drawings to make an image of the finished piece are used for communication with assistants), is done as a flat cartoon of the piece, eventually, if not originally, full sized. Colors are usually approximate, to be matched to exact colors from particular manufacturers. Since colors vary, for hand crafted work, the glass selection is often part of the artistic process. The full sized drawing is reproduced a couple of times. Each piece is marked and may be color coded. One is commonly cut up using scissors that remove the same gap as the lead came or copper foil will make. These pieces are used to plan the layout on the various sheets of colored glass. If a layout is to be done repeatedly, the pieces may be cut from thin metal. Another copy of the cartoon, commonly reversed, is pinned to the layout board for working on the piece. Life is rather more complicated for multisided or round lamp shades. For hand blown factory work there is a planned layout to determine how many people are needed on the team and the quantity of various glasses are required for handles, lids, bases, etc. Since almost no factory work is done these days, such planning is not widely used.
