      [​IMG]The advantages of using GD&T (General Dimensioning & Tolerancing) in your drawings – My Story Edit
      Here’s the job I was working on a long time ago – a massive granite beam held in place with M20 tie-rods in an anchor plate. The clearance holes in the beam were Ø30mm, so lots of room.

      Hello Gareth, I was doing a drawing of a battery powered device to move a swing pool bulkhead (manually on a board), I was doing the drawing at half size to get good detail and be able to provide all the required dimensions. My boss was very unhappy as it reminded him of an incident where he drew a railway carriage coupling at half size when he worked for Queensland Rail. The workshop actually manufactured the coupling at half size so he decided not to let anyone working for to draw anythingat half size.

      Interesting anecdote, newbe. I don't think there's anything wrong with drawing to scale so long as dimensions are shown clearly on the drawing and the drawing scale is clearly marked. If the manufacturer gets it wrong despite this then I'd say it's their own stupid fault!
