Official parts with errors/typos

Hi all.

Working on coding some Java libraries to handle LDraw libraries I hit some parts with errors. Following a brief list with errors/typos I found:

* 3842a.dat uses BFC CERTIFY INVERTNEXT
* 3842b.dat uses BFC CERTIFY INVERTNEXT
* s\3068s101.dat uses color 391 (unknown)
* 973psk.dat uses color 391 (unknown)
* 4150p02.dat uses color 354 (unknown)
* 973p7b.dat uses color 354 (unknown)
* s\2528s01.dat at line 385 there is a triangle with 4 vertices
* s\6582a.dat all quads are "bow-tied"
* s\6582b.dat all quads are "bow-tied"
* s\6580a.dat all quads are "bow-tied"
* s\6581a.dat all quads are "bow-tied"
* s\6594a-c.dat all quads are "bow-tied"
* s\6595a-d.dat all quads are "bow-tied"
* 2907.dat some quads are "bow-tied"
* s\6579a.dat all quads are "bow-tied"

Hi all.

Part 3678b.dat "Slope Brick 65 2 x 2 x 2 with Centre Tube" uses wrong "tube" on bottom.

Tube using "stud2a.dat" but its size is wrong (should be "stud4a.dat"?). Checked on Bricklink, LDD and LDraw editor (no check in real part, I don't have one).

Attached screenshot file shows 3678b (right, with green selection box) and 3003 (left) to compare underside tubes.

Hi all.
While building this, I noticed that metal detector (part #4479.dat) bar seems too large. Part file reports scale of 6 but I think correct value is 4.

Yes, it is wrong. And a comparition with LDD data reveals even more issues.
This part is currently present at the PT, so these issues can be fixed now.

trans-red is ldraw. green is LDD

One more:
Part 6216.dat (Brick 2 x 4 x 2 with Curved Top)
Underside "stud3a.dat" and reinforcing internal ribs are 1.5 LDU too short. Internal "stud4a.dat" is correct.

"stud3a.dat" on opposite sides are 4LDU too short.

PS: can I submit correct models? How can I do?

Thank you

These 3 parts have a naming issue:
87994.dat Bar 3L
87994p01.dat Bar 3L with White Ends Pattern
2714.dat Bar 7.6L with Stop
All three should have 2 spaces between Bar and the length like 30374 and all other single-digit length bars.

The geometry of the 9V points (2859 & 2861) is wrong; the end of the branching track is slightly off where it should be. They also have issues with gaps and overlaps.
I've started work on their PF counterparts. Once they're done I might fix these.

I'm making more Stormtrooper torsos and started looking at the other patterned part for the trooper.
Is this helmet correct, or is this a 'misprint'?

[Image: x130px2.jpg?0]

IMO the divided look of the 'mouth' is a misprint, and our current version of the helmet should be changed.

   

The pattern seams to be printed in two sections. One left side and one right side stencil that happened to be very misaligned on the part that was used as a reference when 30408p01 was made.

The headdresses 90462 and 30168 are both placed to low. They need to be lifted by 2 ldu.
Best seen from behind. The backside/bottom is placed inside the torso.

The Tile+Sticker shortcut 2431d01 has a bad origin. It is placed 1 ldu above the surface of the brick.

A corrected version is sent to Admin, but how do we handle the change in origin best?

A "a" version + ~moved to?

I suggest instead
- obsoletizing the ...d01 shortcut
- creating a new ...d02 with correct position

It has already been done by our excellent Admin at 2431d02 and 2431d01.

I'm not sure if this is the 'correct' topic for this, but I noticed these 2 different patterned parts represent the same physical part: 3068bp14 and 3068bp31 both seem to be 3068bpb0148.

There is a color difference between the two files, but I can't seem to find information about 2 versions. To me, it looks like 3068bp14 has the best colors.

I think this is the third time the same error is reported. Might be time to correct it now....

Recently here, but the first time here

I'll follow the info from JC Tchang to Philo, and update the parts and send them to PTAdmin.

The 2x4 wing 51739 is not correct. It should be possible to place two of them next to each other.

   

I'm reworking it, and also creating the new 2x2 wing.

I think the ball on these two parts are too small.

[Image: 30082.gif?0][Image: 30395.png]

30082                                                     30395

They should fit inside any of the towball socket parts, but are only 14 ldu, intead of 16 ldu.

Would it be OK to simply resize the ball, or do they need to be renumbered too.

I think the angle of the barrel on the two guns in the batman accessories pack 55707a-55707e are wrong.


.png   Image 1.png (Size: 21.25 KB / Downloads: 21)

TrRed is ldd part 62885. Blue is ldraw part 62885. Yellow is ldraw part 55707a.

   

TrRed is ldd part 85973. Yellow is ldraw part 55707b.


At Bricklink 62885 is described as similar in mold to bb192 (a part included in 55707, only difference is the length of the barrel)
At Bricklink 85973 is described as similar in mold to x1608 (a part included in 55707)
https://www.bricklink.com/catalogItemInv.asp?P=55707

I don't have any of the 55707 accessories, but I do have the newer parts. I tried to measure the angle of the Tommy gun, and think it should be the same as in ldraw part 62885, 17 degrees. Not 26,81 as in 55707b
