Thanks to Rob Kirkham for pointing out that I never published this post on the weekend, and then referred to it on Monday evening.
With the drawing matching the ground as modelled, I broke it into pieces so it would fit on the laser. The pieces follow the natural edges in the final scene, so hopefully they will not be noticeable.
Then it was a simple matter to upload the pieces and watch the laser do in a few minutes what would have taken me a day or more. Interestingly, the barn got smaller when traced from the photo; it’s still a large barn, but I think the smaller size will dominate the scene a little less.
