Here are twenty more useful constraction parts I'd love to see added. Parts with multiple Bricklink/Brickset listings have multicolored variants that should also be able to be generated in LDD:

• 87844 (Bricklink/Brickset), last used in 2010.
  
• 87839 (Bricklink/Brickset), last used in 2010.
  
• 87825 (Bricklink [1|2]/Brickset), last used in 2010.
  
• 61808 (Bricklink [1|2]/Brickset [1|2]), last used in 2010.
  
• 53544 (Bricklink [1|2]/Brickset [1|2]), last used in 2010.
  
• 43559 (Bricklink/Brickset), last used in 2010.
  
• 44814 (Bricklink/Brickset), last used in 2010.
  
• 47306 (Bricklink/Brickset), last used in 2009.
  
• 47312 (Bricklink/Brickset), last used in 2009.
  
• 47313 (Bricklink/Brickset), last used in 2008.
  
• 57536 (Bricklink/Brickset), last used in 2009.
  
• 60901 (Bricklink/Brickset), last used in 2010.
  
• 60930 (Bricklink/Brickset), last used in 2010. On a side note, this part has maybe the best official name ever. It's not a jetpack, it's a Rocket Rucksack!
  
• 60894 (Bricklink/Brickset), last used in 2010.
  
• 60895 (Bricklink/Brickset), last used in 2010.
  
• 60899 (Bricklink/Brickset), last used in 2010.
  
• 32551 (Bricklink/Brickset), last used in 2008.
  
• 32552 (Bricklink/Brickset), last used in 2010.
  
• 53548 (Bricklink [1|2]/Brickset), last used in 2009.
  
• 53549 (Bricklink [1|2|3]/Brickset [1|2]), last used in 2009.

Additionally, the following ten parts are already in LDD, but need multicolor to be added:

• 11302 (Bricklink [1|2]/Brickset)
  
• 11439 (Bricklink [1|2|3|4]/Brickset)
  
• 32558 (Bricklink [1|2]/Brickset [1|2])
  
• 53562 (Bricklink [1|2|3|4]/Brickset [1|2])
  
• 57539 (Bricklink [1|2|3|4]/Brickset [1|2|3|4])
  
• 57557 (Bricklink [1|2]/Brickset [1|2])
  
• 57558 (Bricklink [1|2]/Brickset [1|2])
  
• 61804 (Bricklink [1|2]/Brickset [1|2])
  
• 64272 (Bricklink [1|2]/Brickset [1|2]
  
• 64297 (Bricklink [1|2]/Brickset [1|2]
  

Additionally, parts 98588 and 11164 should each be able to support THREE colors each, not just two. See here and here. 98588 ALWAYS has three colors, while 11164 only has three colors in one set (44009 Dragon Bolt).

EDIT: Sorry about the double post. I thought it was removing some of my links because there were too many links for one post. It turned out to be due to a formatting error on my part.

I could still stand it if 424 were added.

The old technic 1x4, 1x6, 1x8 and 1x10 plates (the ones with hollow studs and holes in the ends).

I've been compiling a list of bricks missing from the sets I've contributed to the Official LEGO Sets made in LDD index topic. I've got plenty of other bricks that I would like to see added to the palette, but for now, I'll get this already-long list out of the way.

I've listed these bricks from "appearing in the most sets" to "appearing in the fewest sets", in regards to the number of sets I've contributed (not in regards to how often they show up in LEGO sets in general), which is noted by a number in parentheses following every part name. Wherever I could, I listed the part number and name as listed on Brickset, which uses LEGO's official numbers and names; where I could not, I substituted in numbers and names used on Bricklink or Peeron (which may be unreliable). Parts among this list that I would especially like to see the most are bolded to give them priority over some other more-often recurring bricks such as rubber bands, which are useless in the LDD software, or bricks with similar elements that are already in the software and are thus easily substituted.

Excellent list Peabody!

Seeing as North America isn't getting the Invasion from Below Hero Factory sets till march. How about they add all the new molds made in the winter 2014 Hero Factory wave. That way us in North America can play around with the pieces while we wait.

Also these pieces I want added

All Chima Ultrabuild Heads

All Super Hero Ultrabuild Heads

The new ball and socket joints used in the upcoming Mixels and Legends of Chima Legend Beast sets

Power functions battery box http://www.bricklink...m.asp?S=88000-1 or http://www.bricklink...em.asp?S=8878-1

I'm still not even getting into the whole list of bricks that I want to index more sets rather than bricks that I need to correct the errors in my already-indexed LDD sets. And... unfortunately, after indexing 1353 Car Stunt Studio, I was double-checking the part inventory on Brickset and realized that nearly every transparent brick that is identical to some opaque brick has a different part ID. Should we just ignore that? Problem is, LEGO Digital Designer doesn't quite ignore it; for instance, 6188 Nose Cone Small 1X1 - Tr is in the software in addition to the standard 4589 Nose Cone Small 1X1. As annoying as it is, we can't just have a couple transparent bricks in the software and pretend that the rest don't exist.

So, here's a list of transparent bricks that I need to correct my previously-indexed sets. Many of them are in an apparent "300XX" series of transparent bricks. Like the previous list, the number in parentheses denotes how many LXF files of mine require this brick... keep in mind that I currently have 120 sets indexed over in the other topic, and the first brick on the list shows up in nearly half of those sets. As I said, this will be annoying to correct... but hey, anything for best possible accuracy.

[,,,] ... but hey, anything for best possible accuracy.

On the one hand you are right: LDD should be as exact as possible. But on the other hand that issue should IMHO get a very low priority: As long as the shapes are indistinguishable, there is no urgent need to have a brick both with its solid and its transparent ID. Existing bricks like 6188/4589 shouldn't get removed or unified though, but adding all the missing 300XX transparent clones of existing bricks should not be done until other unique shapes are added (like the various raised baseplates for example), even if the brick was only used in a couple of sets: Correct me if I'm wrong, but as long as there is no visual difference, it does not really matter if a round plate 1x1 is actually a 4073, 6141 or 30057. TLG might have good reasons giving different IDs to transparent and opaque versions of the same design, but as far as LDD is concerned, that shouldn't make much of a difference. But as long as unique bricks like 4626 or the Friends minidolls are missing, whole sets remain unfinished since there is no adequate substitution: That should be tackled first! In let's say set 6379 you might replace 4626 by something like 3747, but that won't work in set 4525 for example. So before tuning the accuracy, all the currently missing rare and old parts should be added first. That allows avoiding ugly workarounds and custom brick-built appliances (I don't want to call them solutions) and greatly helps making complete and accurate sets, much more than the transparent clones of existing solid bricks would. Your list definitely will be helpful in the long run, but I guess it is nothing to be considered for the very next LDD update.

You do raise very valid points, pbat. I just figured that I'd throw that list of transparent bricks (and that's not even the whole list of all transparent bricks - just those that happen to show up in the 120 sets I've indexed) out there because, as it currently stands, LEGO Digital Designer updates do include a lot of functionally/physically-identical bricks. For instance, the newest update (4.3.8) includes 15714 Wall Element 1X2X1, 2399 Brick 4X4/18, and 2625 Stem Plate 7X6, all of which are functionally and nearly-physically identical to bricks that were already in the palette. I just figured, "If LDD is already making an effort to include these nearly-identical brick variations, why not give them a few suggestions on which ones to include?"

I do agree that, compared to more complex bricks that are missing from the palette, these should get low priority. On the other hand, they should be fairly simple/easy additions to the palette, so it might also be a good idea to just get them out of the way as quickly as possible so the LDD programmers can focus their efforts on those larger baseplates and complicated minidolls and the like.

Instead of 4865 (which has sharp corners), 15714 has soft rounded corners. You can actually see the different visual appearance, but moreover you can feel it by touching the bricks. Likewise the 2399: It cannot be placed upon a 4x4 plate, while the similar 50373 can due to the cutouts. Likewise the 2625: It cannot be placed on top of a 16x16 plate, while the similar 50303 can due to the cutouts. Those are examples where it is perfectly usefull to have both variants in LDD: Those pieces are rather similar, but just not fully identical. Or take for example 2339, 14395 and 76768: They look pretty similar, but you can easily recognize some (small) differences both in real life and in LDD.

But a transparent 30002's shape is in no way different from an opaque 6269's. TLG might have to handle them differently during production, but as far as LDD is concerned, there is absolutely no visual difference between those two design IDs: In LDD you could make a 6269 transparent and a 30002 opaque. So if LDD omitts the transparent 30002 in favor of the identical shaped opaque 6269, this is far less important than if it omitts 15714 in favor of the similar (but slightly different) 4865.

Of course it would be easy to copy&paste 6269 and call the duplicate 30002. But what's the point of doing so? The brick palettes get (even more) unclear and confusing and the benefit would be actually zero. Instead of transparent duplicates of opaque bricks (or vice versa) I'd rather prefer if some sort of alias could be introduced for transparent and opaque design IDs: If you filter for 30002, LDD should offer 6269 instead.

If there is really more accuracy needed in LDD, rather things like 4081a and 4081b or 3962a and 3962b should be distinguished, where the visual appearance of different designs is (slightly but observably) different. That includes bricks, that retained the same design ID but changed their actual shape during the times, like 2578a/b.

A little note about similar but different designs.

LDD includes the bar 6140 and not the similar bar 4873.

As you can see, these bars are very similar in appearance, so that you can think you can use one instead than the other in your sets. There is an error, but it is an acceptable error.

The true is different: the two bars are not equivalent, one of that is more versatile than the other, and unfortunately LDD includes... the other. A different choice, that is include the more versatile version, would be much better.

To better understand what I mean, take a look at my Galactic Peace Keeper: I was not able to fit the antennas 3957 inside the bar, because holes was closed, and that prevent me to correctly assembly the set.

Moral of the story: not all similar parts are equivalents, and if only one should be included, then it would be better that is the more versatile one.

I understand your point Calabar, but IMHO it's better to have the brick version in LDD that is actually used in the most sets and is most recent, even if it would be it's slightly less versatile. The reason is that for the most part, I use LDD to build MOCs, and then I want the bricks in LDD to be the ones that are most easy to find in BL. If the brick in LDD has some open holes for example, then I'm tempted to use the holes, only to discover later that that part is much more rare, more expensive, and doesn't exist in so many colors.

Also, I could add to the discussion the list of bricks that we forums users earlier (I think in a topic a year ago), found unnecessary duplicates, i.e that cound be removed from LDD. Any comments to that? Any additions?

Anyway, the advantage of the more versatile part is clear: with it I can cover all the cases, while the other choice prevent me to work on old school designs (admitted that the more versatile design is an old design, that is not necessarily true). As DBM is not active anymore, I can't see any advantage in use the less versatile part.

Besides, if I use Bricklink as source of the parts for my MOCs, I can retrieve both the parts, and not ever the present part is more easy or cheap to buy.

I still think the the best choice is the one that grants the greater flexibility, because it is more suitable for more people and more needs. If I'm building a MOC, frankly I don't mind if someone think that I should not be temped to use that piece, I want to use that piace and I can easily have it (maybe even I have a lot of these parts in my LEGO collection and I don't need to buy that). This is not a matter of use legal or illegal designs.

Thanks for the list, I'll take a look at that.

Anyway, as you can guess, I think that no piece is unwelcome and there is no need to remove even similar pieces since they are recognizable from part's number and description. If a builder want simplicity he can use the LDD mode instead than the extended mode.

Generally I agree, but please have a look at the parts, and you'll see that some are not only similar, they are exactly the same - the reason they even are in LDD in the first place is most often due to a mistake by the LDD Team (they let it pass through without realizing it was just a replacement DesingID for a previous part).

But please have a look, and post any comments

Of course it would be easy to copy&paste 6269 and call the duplicate 30002. But what's the point of doing so? The brick palettes get (even more) unclear and confusing and the benefit would be actually zero. Instead of transparent duplicates of opaque bricks (or vice versa) I'd rather prefer if some sort of alias could be introduced for transparent and opaque design IDs: If you filter for 30002, LDD should offer 6269 instead.

That would probably be the most ideal solution to the "transparent brick" problem; simply making it so that both IDs exist in the LDD palette but the transparent ID redirects to the opaque ID. That way, it wouldn't be considered an "error" if your LXF used 6141 instead of 30057 and would simultaneously lift the error from LXF files without needing to go back and change each LXF.

Looking at the LXF that Superkalle posted, I can identify (at least, based upon the brick names) 6188 and 74968 as being examples of these duplicate transparent IDs that already have presence in LEGO Digital Designer; would it be better to keep these int he palette, or to merge them with the opaque IDs with the previously-suggested solution in mind? I'd check the rest of the IDs in the LXF on Brickset to see if one ID applies only to certain colors while the other ID applies only to other colors, except Brickset's server has been acting really unreliable this weekend and so I cannot see for myself.

It is notable that there are a few other minute differences in some of the pieces. 92756 and 96856 are each more considerably detailed than 30410 and 4530, respectively. The "bars" near the top of of 23306 are also slightly thicker and more spaced out than those on 64567; based on the brick names, I'd wager that one ID is the original Metalized Silver version while the other ID is the more common and modern Medium Stone Grey version, but, again, I cannot check Brickset because it's down. 93888 and 97492 have more stabilized undersides than 3007 and 30144, respectively, and thus I'd guess that the former is a more modern version of the latter.

Not included in that LXF for some reason is 30104 Chain 16 M and 60169 Chain 16 M. Based upon what I've seen on Brickset, the latter is used in more modern sets (i.e. 2006ish to present) whereas the former is used in older sets (i.e. through 2005). Quite annoyingly, 30104 is not flexible, which means that 60169 is much more versatile in LDD's software. Otherwise, they are identical so far as I can tell. Were they to merge under a single ID, should it be the old ID redirecting to the new ID or vice versa?

While we're on this subject, in an older version of LDD, there were two versions of 90462 Nemes, with the other version presumably (but not confirmed; I don't have the part ID) being the older one included in the Adventurers and Studios themes and the 90462 version presumably being the modern version included in the Pharaoh's Quest and Minfigures lines. Since then, the other version has been removed from the palette, with no part ID redirecting to 90462. I think there were some minute differences in detail, but otherwise they were identical.

I have an other question about similar parts. Why can't the LDD Parts Design team just use i.e. 2578a for a part and 2578b for a part with the same DesignID but different appearance?

I've heard something that it was not possible programmaticly. But WHY not? They can save the files as 2578a and as 2578b on their server. If you search LDD for 2578 you get both versions. That way we can have both designs.

I mean, the DesignID in LDD is just used as a name and search query.

This should solve all the 'double part' problems.

Since 2578a was used in as little as 4 sets and 2578b in only one single set a long time ago, this part is simply not important enough to make expensive changes to the design ID system: Unlike bricklink IDs, design IDs do not contain any letters, but are integers and thus can't be easily changed in databases and so on. Giving part 2578b a free integer design ID of let's say 25780 or 25788 thus might be a solution. I guess reusing the already existing ID 2578 for a new part with a different shape was an embarrassing mistake TLG would like to forget.

Anyway, the design ID is used for much more than naming LDD bricks: Not only the shape, but also the material used distinguishes different IDs. That's the reason why identical shapes get different IDs when they only differ with regards to opaque versus transparent. Since the crude plastics are to be handled differently with regards to temperature, pressure and so on, transparent and opaque parts can't be produced onto the same machine without modifications, even if they share the same shape. That's the reason for the whole mess we encounter in LDD. Changing the ID system and introducing something like a shape ID would be too expensive and too confusing I guess.

Generally I agree, but please have a look at the parts, and you'll see that some are not only similar, they are exactly the same - the reason they even are in LDD in the first place is most often due to a mistake by the LDD Team (they let it pass through without realizing it was just a replacement DesingID for a previous part).

I haven't the time to take a look at the list yet, but if the insertion in LDD is due to a mistake, obviously I agree with their removal.

I'm less sure for bricks that are identical but TLG uses different ID due to other reasons (for example the material). In this case maintain both the bricks (with different set's number) can be a good thing because when reproducing an official set the result is more accurate. In other situations this replication is not much useful, instead.

(Sorry, can't find the part numbers.) I'd say all the parts used on the ARC Trooper that aren't in LDD, as they'd be very useful, well, except for the helmet. I'd also think the Clone Commander's parts should be in LDD, as they're good add ons to Clone Trooper's armor. We should also have the new Phase II Clone Helmet with decals to be put on there. --Knight

I'm looking for the nougat spike pieces you can find in this set, and it doesn't appear to be in LDD. I can't even locate it on Peeron and it's missing from Brickset's part inventory for the set. So that is one part I would like.

The part number to search for is 64727. It's in the last category (animal parts) of LDD extended mode. It's also available in several colors in basic LDD mode, but Nougat is not one of them.

Thanks for that.

I wish it had the old windows with the lip on them.
