[KEY TOPIC] LDD 4 Bugs and brick errors

[legofreak_85]

...and the funny thing I've noticed is that if you turn the feet the other way around, it will suddenly work.

Quite true, but try saving and reloading the file. LDD still won't accept the parts and removes them automatically.

Anyway, I've reported all errors found so far to the LDD Team. Let's hope for a fix update early 2014.

Thanks, hope the next update will bring us some new bricks

I encountered a problem with part 30387. When the hinge clip is attached to part 44567 (either right-side-up or upside-down), it refuses to hinge to either 67.5 or -67.5 degrees, which should be one of the normal intervals for it to "click" to. Other parts like 30365 or 30388 do not seem to have this issue, nor does 30387 when it attaches to other parts like 30389.

Well spotted.

I may have found a bug with the old dragon. I can't get the wings to go on because the clips on the body are not at a nice angle.

[Classicsmiley]

I don't think it's a bug. Lie the wing parallel to the ground, then try to attach it. It should automatically "snap" right in.

I can't get it to work. Have you tried it?

Edit: Never mind. It finally worked.

Okay, this one isn't exactly a bug. But part 60800 has a problem whereby the default connections don't line up when you use it as left and right shutters (for instance, with part 60583). Unless you exploit the rotation tool to line them up, one will always sit slightly higher or slightly lower than the other. The standard connections ought to be symmetrical so that they can be more easily used this way, since it's the primary way this part is used in sets.

EDIT: Also, I encountered a boundary error when building the set Rescue Reinforcements. It's the part on step 24 of the instructions, where the chicken peers through the spyglass. It seems the only way for it to work is for the chicken's beak to jut slightly into the hollow stud of the spyglass, but either the chicken (95342) or the spyglass (64644) has a boundary error preventing this.

Part 93062: "bone" and "boot" parts still can't be coloured separately.

[Aanchir]

74261 does not have connectivity with any 10.2mm ball with guides, such as the center ball joint on parts like 90609 or 90607, or the shoulder and waist joints on parts like 90625 or 90626. It also collides with the square guides if you try to place it using scaffolding at any angle that is not within a certain margin of a 90-degree interval. It should have both connectivity and free one-axis rotation on any ball with guides, as in the neck construction of set 44009.

Good find. Will certainly be reported with High Prio.

Can you explain the issue with re-creating 44009?

[Aanchir]

Can you explain the issue with re-creating 44009?

Step 4, page 6, where you attach the friction joints to the shoulders, is not possible in LDD except by using scaffolding. There is no connectivity between those balls on the shoulders and the friction joints, even though the ones in step 5 on the next page work fine.

Balls with and without guides are treated differently on LDD because a ball cup or ball snap on a ball without guides has three axes of rotation, while a ball cup on a ball with guides has only one axis of rotation and a ball snap on a ball with guides has no axes of rotation (it snaps to the piece at 90-degree intervals). That's not the problem here — the problem here is that for whatever reason, the friction ball cup 74261 doesn't have connectivity with balls with guides at all.

Stage 16, page 25, where you angle the neck upward, is not possible even with scaffolding, because LDD says there is a collision between the corner of the square guides on 90623 and the curved sides of 74261. This should likewise be corrected, as the connection allows for free rotation in real life.

I'm not sure I'm supposed to be able to do this with 64230 spiral tube:

It also happens with 4070 (erling brick), and selected other SNOT bricks with hollow knobs such as 4733 (at any angle), 52017; round bricks such as 3062, 3942, 4859, 6188, 59900, 71075; and pretty much anything else that I imagine would require disassembly of the spiral tube to achieve.

This doesn't happen with 6211 (a part which cannot be manipulated by the flex tool), so I imagine all this weirdness is a side-effect of the behaviour which allows flexible items to "snap" into place.

LXF Example (LDD 4.3.8 / Brickset 1264)

ALSO: heeee, I think I made the tube angry with all my messing about - it went all skinny in the middle:

[Lego Otaku]

Some "spiral" tubes do have detachable end so it may be possible to slide anything with 3mm hole into the tube. But it is not supposed to twist itself thin. I had similar issue with 3mm tubes about a year ago, guess LEGO hasn't figured how to fix that.

[kamos]

Well, I had similiar "problem" year ago too:

http://www.eurobrick...50#entry1552813

check the third spoiler, feel free to download the file, it still works

click with hinge tool around the 2555 holder plate, you should see small box around the cable and then hold left or right arrow for awhile, you should get similiar result

All the half Technic beams but one won't let studs attach to it.

The parts are:

44374 TECHNIC LEVER 3X120

99773 TRIANGEL

32250 HALFBEAM CURVE 3X5

6632 TECHNIC LEVER 3M

32449 LEVER 1X4, WITHOUT NOTCH

11478 LEVER 5M

32017 TECHNIC 5M HALF BEAM

32063 TECHNIC 6M HALF BEAM

32065 TECHNIC 7M HALF BEAM

32006 TECHNIC LEVER 4M

32249 HALFBEAM CURVE 3X3

32056 TECHNIC LEVER 3X3M, 90°

32251 HALFBEAM CURVE 5X7

Studs should be able to attatch to them (see the Medium Lilac parts in 2905 TRIANGLE).

Next to that, the Cool Yellow studs go through 32250 HALFBEAM CURVE 3X5

---

It is not possible to place the 2L axle correct in the axle holes in set 76013 Batman: The Joker Steam Roller. That is because 2460 PLATE 2X2 W. VERTICAL SNAP (yellow circled) only have 2 connection options for the half beam. Whereas in real life the half beam can slide the entire length of the pin.

The half beam should be in the middle of 2460, which is not possible.

The arch 6060 is supposed to fit under the bow of 2339 (and maybe the similar 14395 and 76768 as well). It definitely works in real life and apparently used to work in earlier versions of LDD as well: For images have a look at this thread. Obviously the bounding boxes of 2339 got messed up with one of the recent updates.

Collision errors building official alternate models of 7700 and 7701.

In 7700 it is impossible to connect the nose of the vehicle to the bottom part. So I had to rise the part with one plate (that I removed, so the nose is disconnected from the body of the veichle).

Besides, the windshield don't connect the 2x1 plate in the "more ahead" position.

In the 7701 the shoulders (both right and left) don't attach the brick structure below because of a collision error. In this case too, I had to rise the parts using a plate, so that shouders are disconnected from the body of the model.

Here you can download the lxf files.

Found a new error, I think. Axles do not go into part 98302 as far as they should. A 32062 2M Cross Axle ought to be able to slide in by its full length (which is why 98302 replaced 3475 in the first place), but instead any cross axle inserted all the way extends out slightly farther than it should. I got my first 98302 this past weekend so I can confirm that it should work this way.

While discussing the parts used in the Ghostbuster's Proton pack, we noticed that the handle of the straight whip (part 88704) seemes unfinished : it's lacking the ridges that the coiled one has.

Just a visual bug, though. It didn't block anything from being slid around it and such.

I found a bug with part 14740. When the second-from-the-back studs are covered it makes the studs third-from-the-back disappear as if they were covered. See here, on the bottom left.

Hello Guys,

I would like to report that 3 of the 7 new CORRUGATED PIPE are not correct, the pins cannot connect:

LXF File

As a workaround axles can be used to connect the pipes.

I just found a bug that prevents an official build:

When trying to build official model 7066 (Earth Defense HQ) you cannot place the top two red cones (6188) on each "missile pod". It seems to think that placing 2540 above it prevents adding the top two flick fire missiles on each "pod", but in the real set, it doesn't.

To reproduce this error, open the lxf from here and you'll get the "4 bricks have not been placed properly" error. Try and place the bricks, and it won't work.

I'm pretty sure this bug wasn't present in at least some earlier versions of LDD?

That is actually what appears to be an illegal build, since the cones will collide with the 2450 (although it is barely touching it I agree). To understand the problem, you can replace the 32000 with a 11211 and it should work. This is because the center of the technic holes of the Technic brick are actually placed a tiny bit higher then the center of the stud on a 11211 (and similar bricks).

So why did it work before? Well, I think you are right in the scene that the collision volume of the cone has actually been improved (better aligns with the visual geometry of the brick), so what worked in an old version of LDD, now doesn't work anymore. (i.e. improving the digital brick quality has revealed a previously unknown poor build technique from TLG).

[dhumahn]

Not sure if this one has been posted or not...part 4715 (underpart for stretcher), works with the stretcher, but doesn't connect with part 4276 (either just one or a pair), even though it is supposed to??

Trying to build set 6480 at the moment.

[kevin8]

With the last version of LDD I have continuous problems with baseplates. I have not to move them if put under a building or LDD simply closes...
