[KEY TOPIC] LDD 4 Bugs and brick errors

Looks more like an anti-stud than a stud but still an error, and still strange that they make that kind of error. Maybe because it’s an obsolete part, not made anymore, they don’t care….

Oh, another way to check: find a (small) set that uses one and look at the instructions. (e.g.: http://bricks.argz.com/ins/1280-1 )

Thanks for that, but check this out as well: I took this screenshot directly from LEGO’s official Bricks & Pieces and Part 75535 seems to have a Knob on one side even though it shouldn’t have! So did LEGO get this Brick wrong themselves as well?

Yes, and it’s LEGO I meant by “they” because Brickset’s pictures (and a good part of their data) directly come from LEGO.

I was looking at ways to connect the Design Shape W/ Tube, Crosshole (Part 25214) and discovered another bug in LDD. In Set 10257: Carousel, two of these in White are connected together to form the neck of the White Swan with the help of a 2M Cross Axle W. Groove (Part 32062) in Red. I intend to replicate this build with one of the tubes placed the other way round to form a sort of S-shape. However, even when I’ve inserted everything to the maximum there is still a gap in between the two tubes!

Referring to my earlier post, I have tested the Bricks in question again by inserting a Red Cross Axle into two Transparent Tubes, one on each side. This screenshot shows the results where a gap is clearly visible in-between the two Tubes. As seen in Set 10257: Carousel and a few sets from The LEGO Batman Movie, two or more of this Tubes are often used right next to each other to form a series of pipes (which is also what I’m using the Tubes for in my current build). Therefore, could the issue in LDD be that the two hollow sections inside the Tube are not deep enough, or is the Cross Axle slightly longer than it should have been? Before I continue to build my pipes with two Tubes right next to each other I need confirmation that this connection is actually working fully in reality. If proved to be fully working I will scaffold one next to the other and place the Cross Axle aside then update my model when this connection is fixed in LDD. Thanks in advance!

Yes, it’s an LDD error. The hollows in the tubes are too short in LDD. It works seamlessly and effortlessly in real life.

For the first time ever, I was able to confirm a new bug in LDD by testing one of the combinations with actual LEGO Bricks! If you follow the steps below to recreate the combination of Bricks you will see that the topmost part is currently not possible in LDD but works completely in reality!

1. Prepare either one of the Bricks below: Shaft 3M Ø3.2 (Part 87994), Light Sword - Blade (Part 30374), Standard Ø3.18 x 53 (Part 4095) or Stick 6M W/Flange (Part 63965).

2. Attach a Round Brick 1x1 (Part 3062) to the top of the first Brick.

3. Try adding a Plate or Flat Tile on top of the Round Brick (any one will do) and in LDD this connection is not yet possible! I was hoping to attach a Flat Tile 1x1, Round (Part 98138) onto the top of the Round Brick to prevent it from being attached to any Bricks further above, and this particular combination has been tested in reality to prove that it works completely!

This is a longstanding issue with LDD whereby the undersides of most parts are not actually programmed as "hollow". You can get around it slightly by making sure that the piece with the 3.2mm bar extends only slightly into the 1x1 round brick, so that it doesn't actually extend into the "stud" that is meant to connect to another part (the easiest way to check this is to turn the 1x1 round brick transparent so that you can be sure of how far it connects). Of course, this workaround only works in situations where space isn't at a premium...

I recently noticed this 2011 Monthly Mini Model Build featuring a brick-built version of Dracula. In the set, 1x1 slopes are inverted to create a chevron pattern on the vampire’s chest, which is a technique rarely seen in official LEGO sets. This unique build is currently impossible in LDD and I want to know whether this is considered to be an “illegal build” and is there an alternative way to build something similar in LDD. Thanks in advance!

AFAICT, it’s legal. There’re similar decors on the Horizon Express 10233-1.

The cheese slope just has too big a collision box in LDD. It happens.
