I have one other technique that I haven’t documented yet. I saw William Howard doing some slanted walls for shop fronts, and had to work out the maths behind it.

The technique is for fitting in a wall that slants in or out by two studs. The slanted section can be any length. Look at the diagram below for 2, 4 and 6-stud long examples:



By comparing the top and bottom images, you can begin to see how it works.

The top image uses one yellow (or blue or green) plate between the two red plates to show the spacing. Now consider the length of the diagonal across that yellow plate, from one red plate to the other. If you rotate that yellow plate, its other diagonal - the same length - bridges the gap just as well.

The same trick works for any length plate. You just need wall or plate hinges at each end to hold the diagonal in place.

(...) Note that this technique is used in the nose of the UCS X-wing over a length of 28 studs: [LEGOSet 7191] ROSCO (18 years ago, 18-Feb-07, to lugnet.build.schleim, FTX)

(...) For the sake of completeness, it's worth to mention this technique not only works for any length, but also for any width of plate/brick. In other words, you're able to slant ? x 2, ? x 4 and so on by mirroring along the diagonal as well, using (...) (18 years ago, 18-Feb-07, to lugnet.build.schleim, FTX)

(...) This is very cool! It seems obvious now you've highlighted it, but I could never have spotted it. (I can't wait to use it in practice!) Thanks for sharing! Cheers Richie Dulin (18 years ago, 18-Feb-07, to lugnet.build.schleim, FTX)
