AutoCAD the drawings are very basic a lot of cutting & shutting from other loom files no time to draw the looms or Diagrams from scratch. Ive around 80 different Diagram/Loom files that ive done for M.A.D the latest is for a Lancia Intergrale it keeps the brain active or something like that. Not sure what happens when I get too old but apparently im good till im 90 so a few years yet.
