The things worth knowing when you make one of these diagrams, and when you hand it to someone else.

What a part number diagram is
A part number split into ranges, each labeled with what it means. What it is for, and what it is not.
How to make one
Type the part number, select a range, write the meanings, place a note, save. Every button named.
SVG or PNG
Which to put on a product page. Decided by scaling, searchable text, print, and what the CMS accepts.
Embedding fonts in an SVG
Without the font, the letters are redrawn with whatever the reader has — and the spacing goes with them.
