Guides (6)
- 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.
- Designing a part number that reads well For anyone about to define a scheme. Stable facts first, one fact per range, characters to avoid, room to grow, where the revision goes.
- Putting the diagram on a page, in a catalog, in a PDF After the format is chosen: how to place it. PNG width, print resolution, dark backgrounds, what to send with it, what to check at the other end.
