Hiya! I made a model of part x351 (or 41850 on other sites than bricklink), imported it into Bricklink's Part Designer and exported it to LDRAW format.
I read on the website I needed to write an e-mail to Orion Pobursky but was unable to find his e-mail address.
Feel free to let me know if there's something I need to fix, because I'm not sure what stuff is required and what is not.

Greetings!  So, went to request these parts for Stud.io, and was told there was no 3D Model file for these parts....  So, while I am still waiting on the Zeppelin Container parts, and seeing as how I need the above parts of a Narrow Gauge Locomotive Project, I figured I'd ask here for help with the 3D model files.  Thanks, have a great day!  Rockatoa, Brickticks out!

Hi,

Can I get the new 2x2 round curved corner brick by any chance

It's from set 77002 - Metal Sonic v Cyclone

The height is 1 brick tall (but no studs) and the inner diameter if you put 4 together is 2L

There are 4 in yellow, on the front of the robot which makes a 4x4 ring.

Hey, haben Sie eine Frage an Sie, gibt es noch andere Programme von LDraw, mit denen Sie Ihre eigenen Teile entwickeln können, abgesehen vom Part Designer? Denn ich bin auf der Suche nach weiteren LEGO Designer-Programmen, in denen man seine eigenen Teile entwickeln kann.

Name on Bricklink is Panel 4 x 2 x 2 2/3 Round with Circular Hole and Studs on Sides.




Couldn't find in official parts or unofficial.

Hello!

I was wondering if someone could look into 4526. It's not quite right. There is some overlap, making it out of system.

The unresolved issues with duplo bricks 11344, 70676, 70683, and 11169 seems to be the orientation. The rules for orienting duplo pieces are not as clear as with regular lego. A good example of the differences is duplo part 3664 and its equivalent regular lego part 49307. As there now are certified duplo slopes in both orientations, this calls for a deeper investigation.

Figure shows 3664 and 49307.

A slope is defined as a brick having less or more width at the top than at the bottom. This includes straight slopes, curved slopes, and inverted slopes.

Regular pieces tend to have the slope in the negative z direction. This applies to 'inverted', 'slope', and 'curved' pieces. A few exceptions exist:

• "regular inverted" in the wrong direction (slope in positive x direction): 18653, 30099, 78666.
  
• "regular slope" in the wrong direction (slope in positive x direction):  45411, 45204, 45410, 54095, 54096, 1942.
  
• "regular curved" in the wrong direction (slope in positive x direction): 6183, 6184, 6215, 4744, 6216, 6214, 30075, 54097, 11290, 11301.
  

• "duplo inverted" in the negative z direction are: 11169 (unofficial).
  
• "duplo inverted" in positive x direction are: u977(2x3) to have it in the same orientation as the two-sided arches, 2301 (2x3), 98224 (2x4), 98252 (2x3), and 4198 (2x4). Here, the longer dimension rule is given precedence over the slope rule.
  
• "duplo curved" in the negative z direction are: 11170 (2x2), 11344 (unofficial), 70683 (unofficial).
  
• "duplo curved" in the positive x direction are: 98252 (2x3), 2302 (2x3), 98224 (2x4), 98223 (2x4), 31213 (2x4).
  
• "duplo slope" in the negative z direction are: 63871 (3x2), 35132 (4x4), 31170 (4x4), 6474 (2x2), 70676 (unofficial), 15580 (3x2), 49570 (unofficial), 35114 (3x2), 29303 (4x2).
  
• "duplo slope" in the positive x direction are: none
  

1. any duplo piece with a curved slope (both convex and concave, inverted or not) is oriented with the slope in the positive x direction (for clarity, this includes arches)
   
2. any duplo piece with a straight slope is oriented with the slope in the negative z direction (there are currently no pieces having inverted straight slopes, but they are expected to be here)
   
3. the longer side is oriented in the positive x direction
   

• unofficial parts 70676 and 70683 can be certified in their current orientation (straight slopes in z-)
  
• unofficial parts 11344 and 11169 must be rotated before certification to yield curved slopes in x+
  
• certified part 11170 must be rotated to adhere to these rules and have its curved slope in x+
  
• certified parts 98223, 2302, 98252, 98224, 3664, 4198, and 2301, all having curved slopes in x+, can remain as they are
  
• certified parts 6474, 63871, 35114, 29303, 35132, and 31170, all having straight slopes in z-, can remain as they are
  

Hello,

The patterns of the printed parts are probably also available in the Lego app.
Does anyone have experience of how to get these patterns? I mean how I can copy these patterns from the app.

Greetings

Manfred

anyone know the angle of the arm bar

Currently, the stud8.dat primitive (Duplo hollow underside stud) results in a too thin cylinder. Widely used, yes, but the thinness leads some parts authors to use the stud4.dat primitive instead. The stud4 primitive produces a cylinder wall thickness comparable to the 4 LDU of most walls. Compare e.g. the undersides of 15515, 98220, 31066, and 15516.

The real parts have most curved walls slightly thinner than the 4 LDU of rectangular bricks, whereas the underside stud cylinder walls are even thinner, but not as thin as the current stud8 primitive.

What do you think about updating the stud8 primitive to having a slightly thicker wall? Perhaps 3 LDU instead of the current 2 LDU?
