Hello all aspiring part authors
Have you thought about becoming a part author, but haven't found parts that are easy enough to model?
There are a number of low-hanging fruits (easy parts) you could author. I strongly recommend beginning with authoring parts that you own so you can observe the shapes in detail and do measurements.
* 41759 Duplo Hand Sign
Use 31925s01.dat for the base and handle. The outer diameter of the large circle is 80 LDU. Remember to subfile for patterning.
* 60776/10563 Duplo Container Box 2 x 4 x 2 Door with Handle
Use ddoorhinge2.dat for the hinges and 18816s01.dat for the handle. The door should be 5 LDU thick, 160 LDU wide, and you have to measure the height.
* 18806/60775 Duplo Container Box 2 x 4 x 2 with Open Sides
Use ddoorhinge.dat for the hinge socket.
* 27372 Duplo Disk with Handles
This is in principle an easy part. However, there is currently not a primitive for the handle. One should be created.
The same handle groove can be found on e.g. 46376 fire extinguisher with elaborate handle (2 grooves only), 24806 camera, 35092 milk bottle with handle, and 27383 cup with stud inside.
* 24417 Duplo Dog Sled
There are some curves, but they should be rather easy to figure out. The front handle has three grooves like the disk, but on a longer cylinder.
The same handle groove can be found on e.g. 46376 fire extinguisher with elaborate handle (2 grooves only), 24806 camera, 35092 milk bottle with handle, and 27383 cup with stud inside.
Disclaimer. While these parts were not on the parts tracker at the time of writing this post, they may have been added since. There may be more parts which are easy to model but not listed here.

Do the underside 'hollows' need to be modeled on each of the radiating bars?
They do not appear to have any function and would only add size and complexity to an already complex part.
Round Duplo brick with radiating bars (31070) BL link.
Picture of underside can be found at ebay link.

Ich habe eine Frage, werden die Software wie LeoCad, LD Cad und LDPartEditor tatsächlich aktualisiert, weil ich bemerkt habe, dass in LeoCad die Teile nicht richtig verbunden sind, weil man nicht wirklich etwas bauen kann, man muss die Teile immer entlang der 3 Achsen bewegen, es ist ziemlich umständlich und zeitaufwändig, etwas zu bauen. Und mit LDPartEditor könnte auch etwas Neues entwickelt werden, denn das Programm ist ziemlich verwirrend, wenn man neue Teile entwickeln möchte, man weiß nicht, wo etwas ist.

| LDraw Part Naming Styleguide |

As many of you know, I've been working on an online LEGO Parts Guide as part of my brickarchitect.com website. I have recently announced that I am planning to turn it into a printed book as well, which I hope will become a valuable resource within the LEGO Community.
One of my goals in refining the online guide and preparing it for a print edition is to ensure my part naming strategy is thoughtful, consistent, and aligned with terms used throughout the community. It's also important to recognize that the shorter part names I use are not meant to be used in isolation, but rather to always be shown next to an image of the part. (The website also allows me to define a longer version of the name which helps with search functionality.)
In order to create consistent naming conventions, I recently prepared a first draft of the glossary, abbreviations, and naming conventions I will be using in the guide.
I wanted to share it with this group for two reasons:
- I would genuinely love your feedback on the approach I'm taking.
- I wonder if there is a similar styleguide for naming parts on LDraw. (If not, maybe this document would be a helpful starting point in creating one.)
Feedback encouraged and genuinely desired!
Sincerely,
---Tom Alphin
--------------------------------------
Glossary
Ø (Diameter) – Describes the diameter if a curved element was a complete circle/sphere.
Arch – Part with downward-facing curve relative to vertical axis.
Bar – Part with cylindrical section that can be grabbed by a clip or minifigure hand.
Baseplate – Very thin and slightly flexible part with studs on top, most commonly currently used in the Modular Building Series.
Bracket – SNOT piece which has an ‘L’ shape, usually with a plate thickness section oriented with studs facing upwards, and a vertical section with studs facing outwards.
Brick – The basic building blocks of LEGO have studs on the top and are multiples of 8mm wide and 9.6mm tall when stacked.
Corner – Part which have a section removed on the horizontal axis. This missing area could be a rectangular area, at an angle, or curved.
Cutout – A rectangular area missing from side or bottom of part.
Door – Part which rotates around vertical axis.
End(s) – Describes one or both ends of a part.
Frame (Door Frame) – Part with large outward-facing opening for door or large window.
Handle – A Bar that is closed on both ends.
Horizontal – Something is lying on the ground. Also described as parallel to the earth (horizon).
Nose – Part which is angled in both horizontal and vertical axis. (Sometimes described as a Wedge Slope.)
Recessed – A rectangular area missing on vertical axis which still has studs.
Rock – Part with irregular and rough appearance.
Pane – Part which inserts into a Window, including transparent parts (Glass) or a lattice/grille pattern.
Panel – Part with a thin wall instead of a full brick wide.
Plate – Part which are 1/3 of the height of a LEGO Brick.
Slope – Part which has an angled section relative to vertical axis.
SNOT (Studs Not On Top) – Parts with studs facing outward (horizontal axis) instead of just on the vertical axis.
Tile – Part with a smooth top surface (in the vertical axis).
Vertical – The way that classic LEGO bricks are stacked. Also described as up/down.
Wedge – Part with angled section relative to the horizontal axes.
Window (Window Frame) – Part with an outward-facing opening in the vertical axis.
Windscreen –Panel thickness part which is angled on vertical axis, usually used in vehicles or spaceships.
Abbreviations
Abbreviations are used as needed to keep part names shorter for part labels and names shown in this book.
L. (Left), R. (Right), Inv. (Inverted), Dbl. (Double), w/ (with), D. (Diameter), ID. (Inner Diameter), Pos. (Position Sensor), Sm. (Small), Med. (Medium), Lg. (Large), XL (Extra Large).
Part Naming Conventions
Part names in this guide are shorter than the names used by The LEGO Group or other LEGO-related websites. These shorter names are easier to remember and save space. They are not meant to be a thorough description of each part; but rather to complement the part image by providing clarifying details and relevant terminology. Where possible, I use the terminology in this glossary to describe each part.
If you want to learn more about a part in this guide, visit brickarchitect.com/parts and search for the part number listed beneath each part.
Criteria for Inclusion
This guide aims to include all ‘common’ parts which are currently being produced. In practice, this means the top 2000 parts which were produced in between 2020-2024 based on a weighted ranking system. Some parts are excluded due to the lack of 3d models required to create custom images. Many additional parts are included in the guide beyond the top 2000 parts, including a selection of useful parts which were released in 2025, and rare parts that are important for the completeness of the guide (such as a complete selection of current electronics).
