Here's an interesting challenge for to see the new year in: What's the largest self-aligning Lego set?
In case you're wondering what the question means, I'm looking for the largest set (in terms of number of parts) where no part requires manual alignment. Or to put it another way: What's the largest Lego set which doesn't require any effort to make sure all the parts are lined up properly?
(I'm looking at you, 1x1 plates...)#40013
Halloween Ghost is a simple example of a self-aligning build. All parts are connected by at least two studs, preventing them from rotating even slightly and thus forcing them to align properly. Consequently, all brick edges run parallel to each other as intended, and it is impossible to build it without that happening.A self-aligning build
Obviously there is still a small amount of play in the above set - it will bend slightly - but not by a noticeable amount, so let's ignore that :)
Conversely, an example that is obviously not
a self-aligning build includes #40014
Halloween Bat, which contains a pair of black Brick 1X1 W. 1 Knob
. Although these are nestled up against other bricks, there is still a 0.2mm gap which allows a noticeable amount of rotation. This means that a perfect build requires the parts to be manually aligned, which causes sadness and despair for OCD types.Not a self-aligning build
Other obvious examples which are not
self-aligning builds include any set which contains 1x1 plates or tiles. An exception to that is when they are not attached to anything, or are only attached to something which has rotational symmetry. For example, a 1x1 square plate stacked on top of a 1x1 round plate still counts as a self-aligning build, whereas a 1x1 square plate stacked on top of another 1x1 square plate definitely is not, as you have to make sure they're lined up with each other.Lots of 1x1 plates - definitely not a self-aligning build!
Slap a load of 1x1 tiles onto a large plate and you'll soon see how awkward and annoying it is to try and get them all to line up with each other. Do the same with 1x2 or 2x2 tiles and it's not a problem (and probably a more enjoyable experience!) So, I look forward to seeing which sets you consider to be the largest of the self-aligning builds! :)
