[KEY TOPIC] LDD 4 Bugs and brick errors

[Zerobricks]

I am not sure this has been reported but neither of the two chain links can be connected to any type of gears.

You just need to work arround it...just lay some link near the tooth gear and use hinge tool to loop them arround.

Another bug I encountered when I was doing 7738: The hole of the 75535b cannot be connected to a stud.

[roamingstop]

That is an interesting one. I assume you mean that a 6961 cannot attach to four 30565 placed as a circle? I wonder if this is a brick bug or not? Because for it to work, LDD would have to know when four 30565 have been placed, and only then allow connectivity, and I don't think LDD at the moment has conditional connectivity.

True. But adding plates underneath does not solve it either as it cannot close tightly to the studs of 30565. Anyway easy to work around.

I actually made a template for that, at least around 24-tooth gears. I'll see about making one for all the sizes of gears that those work for.

When I was doing 7643, I encountered this bug: the 41531 cylinder piece cannot be inserted in this step due to the protruding 1x2 part of a 2x8 plate. Here's the LXF. I did a minor modification just to complete the LDD of the set (replaced the 2x8 plate with a 2x6 and completely inserted inside the body so there won't be any protruding part).

Skeleton leg cannot rotate freely in this skeleton body

Piece 45705 has an annoying collision error with parts placed beside it at a particular interval:

Also, the radar dish 4285 cannot be recessed into the wheel piece 44772 the amount required to complete set 8118 Hybrid Rescue Tank.

Another bug I experienced when I was doing Set 7738: 61483 piece cannot be connected in the hole in the underside of the helicopter, but the instructions clearly states it can.

Can you try it again. There should be a sweet spot where it should connect, but you have to be very precise with the mouse.

[Superkalle]

All bugs so far reported to TLG.

I did several exercises to verify/confirm this error, and here are the results:

a) 61483 fits in the technic hole of the orange piece alone

b) 61483 fits in the technic hole of the black 2x8 piece alone

c) 61483 still does not fit in the combined technic hole of the orange piece-2x8 black plate piece set-up stated in the instructions

d) I used the 61483 piece in another LDD set that I made (3222), and it fit the technic hole of the dark bley piece

Conclusion: 61483 fits in the technic hole of single pieces, but not the two plate thick set-up as in set 7738.

Here's the LXF file if you (or anyone) would like to verify this.

You are right - collision volume brick bug!

You are so right. My mistake, I tried it with 45410. Dooh. PS: thanks for clarying with the pics and LXF

No problem, at first I thought I have an 'unsturdy LDD-unfit hand', now I know I'm as normal as you guys.

You are not normal. No one who uses LDD is normal

I can tell you what the problem is. The piece probably does fit in a stack of two Technic plates just fine. The reason it doesn't work with the aircraft piece and a Technic plate combined is an error I mentioned earlier: the fact that that aircraft piece is thicker than a regular plate. This should not be the case, and caused major problems for me when trying to build the Thunder Driller set from the Power Miners theme.

Once that aircraft piece is corrected, your problem should be solved.

Oh I see, I actually tried and verified it (below), and you're right, the 61483 does fit into the hole of a double stacked technic plate. The aircraft piece might probably be thicker than the normal plates as you said. Great spotting!

Just had a collision error with parts 40387 (Mosasaur, Upper Jaw) and 40374 (Body, 5x2x4 with bush, right). When the neck is angled upwards 22.5 degrees from a horizontal position, the Mosasaur jaw collides with the body. In real life this is not the case. Here's an image:

Note that if part 40374 is removed, though, the jaw fits just fine-- despite that the part it's attached to is symmetrical with it:

Clearly, then, the error is with part 40374 and not any of the other parts involved.

Also, part 30489 (Ceratops Head) has an even more egregious error: it will not connect with the neck piece 40375 at all. It connects fine with other parts that have Technic holes, so there seems to be a collision error involved here.

There's also a rather tame error with parts 40395 and 40396, two neck/tail pieces: the Technic pins on the actual parts are colored black, while the rest of the piece is colored a second color. In LDD, these parts cannot be dual-colored. This never interferes with construction, but it is still a problem if you want to go for exactness.

While doing Set 7630, I encountered this annoying problem, the 64451 bent technic cannot be rotated! (Left) Hence, the end product looks like the one in the (Right).

Remove the yellow brick and now you can rotate it on pin or any other brick. Its the 1x2x1 brick with 2 holes problem!

Thanks a lot Zblj! It's now working!

The stern piece 47404 cannot allow the slope piece 47457 to attach in the position required by the instructions of set 8078 Portal of Atlantis.

I can't verify at the moment that this connection works with the actual brick. but I know for certain that if it didn't it would have been obvious to the designers-- a piece in compression from that angle would automatically want to pop out of place as soon as it was attached (if attaching it in compression were possible in the first place, which it might not be).

It should defintely fit - otherwise there wouldn't be a stud there (at least that's my conclusion).

Not necessarily, because there are plenty of parts that fit on studs that have a much smaller footprint-- for instance, a 1x1 round plate. Still, I think that it would be obvious to the designers if the part didn't fit right, so I doubt the connection is truly illegal.

Yes, and there also seems to be a small indent in the bow bricks to enable a brick to fit.

Oh, and BTW. I reported all the bugs you found on that Atlantis set. The only thing I didn't get was the frog.

[BrickWild]

Here's one that you haven't noticed earlier! I was making a simple telephone set and on the bottom of the slope brick, you can see the keypad decal in the wrong place!

[private_lego]

Boundry error with element 4727 Flower stalk

It is impossible to place 2 elements next to each other.

When you turn the brick 45° it is possible, but then they merge into each other slightly

Placement error with element 6255 Leaves 3 elements

It is impossible to place the element in the middle of 4 studs. Only at the studs.
