Okay, I've compiled a list of all identical or similar brick in LDD. They're divided in 3 categories:
- The Red ones are functionally and aesthetically identical to their counterparts.
- The Blue ones are aesthetically different but functionally identical.
- The Green ones have the same basic shape, but have different functionality. The main culprit of this is hollow studs instead of full studs, that being the only difference in most cases.
In every case, all the Red duplicates should be removed, with precedence given to the most recent DesignID. With regards to Blue and Green duplicates, Blue duplicates should be eliminated in the basic LDD mode (with the same rules as for Red duplicates), to simplify part selection, while both Blue and Green duplicates should be in LDD extended mode.
BTW, the old-style Techic turntable bug still hasn't been fixed, FYI.
What do you say, guys?
It should be noted that the clips 6019 and 61252 are aesthetically identical in LDD not in real life
. This is 61252
, this is 6019
. The same is true of 3139
Also, 4623 and 88072 are not functionally identical
They have different dimensions. If you place a brick on top of the studs of 4623, you can fit a sideways tile between the brick and the vertical shaft. This is not possible with 88072. However, 88072 is not by any means inferior--the easiest way to see how the newer version can be useful is to attach the brick 95820 or 30237 to it. 88072's dimensions are more ideal for lots and lots of applications, since the center of the vertical shaft is 1/2 a module away from the side of the plate.
2376 and 74698 are visually similar but actually slightly different in function. One of them has a loop that is the same width as a Technic half-pin, the other has one that is the same width as a plate. This makes very little difference when using a Technic element through the loop (or just using it to connect to a string or hook), but the older 2376 can be used more widely in System building as an irregularly-shaped SNOT element.
As Superkalle has pointed out in the past, 3063 and 85080 are different in that one has supports underneath and one does not. On LDD this makes very little difference, but in real life this means that 3063 can more easily be built into a sturdy 4x4 column by rotating each layer of bricks 45 degrees.
3455 and 92950 are also functionally different. Elements like 61068, 88930, 93273, and 93604 fit perfectly underneath the newer version, 3455. Not so with 92950. However, I believe some builders are partial to 3455. I can't remember the real-life advantages it offers.
58827 and 95347 are functionally different because they have their horizontal supports in different places (58827 has one halfway up the column, while 95347 has two at smaller increments up the column). Since you can attach Technic elements to a central Technic axle through the open side of either column, this makes a big difference-- the newer version has a sizeable space between the two horizontal supports, between which no Technic elements can be attached.
Those are the most major oversights in this file. There are other subtle functional differences, like the amount of friction certain hinge pieces offer, but in LDD these could never be made to amount to functional differences unless a physics engine of some kind were installed, and even then it's doubtful many builders would make use of such differences.
