The Duplo cannons are composed of multiple physical pieces screwed together. Looking specifically on the cannon with locking ring and red button 17178c01 or 94886c01.

What is the minimum that need to be modeled?

Some motors, projectile launchers, and springs have been modeled down to each screw and separable part even if that has meant the creation of (sub)parts with u numbers. Obtaining subpart numbers and internal structure requires opening the assembly, possibly destroying its play-ability in the process.

Rubber insets are sometimes modeled only by their visible parts.

Can the firing button be modeled as a red surface or does it need to be a separate subpart?

How accurately does the internal structure (metal spring and projectile guides) need to be modeled?

Do the screws need to be modeled as separate parts?

Hi,

this version gives you just a pair of small improvements.

BrickLink lists two duplo cannon balls:
54043 Duplo Cannon Ball 1/2 with Large Axle Connector
54043b Duplo Cannon Ball 1/2 with Large Axle Connector and 4 Holes in Top
These parts have visibly different geometry, the newer is more reinforced and has 4 holes.

How should they be numbered in LDraw? Keep 54043 and 54043b or go with a and b versions?

I've long struggled with parts that have two curved edges close to each other, but not having the same point of origin. The task is to fill in the area between the curves.

If the curves are far enough apart, I can use tndis and chords. However, if they are close, then I'd have to rotate chords and tndises, which isn't ideal.

Luckily, we have tang for the inside (in yellow). This eliminates the need to rotate ndises, but effectively doubles the number of points. If the inside and the outside of an area to be filled have significantly different number of points, then the result is a large amount of extremely narrow triangles, so this is to be avoided.

What if we had an inverse tang (in black) to be used for the outside? With an equal number of points, it is easy to fill the light gray area with quads.

Hi all,

I think I found some duplicate triangles and quads in some part files. Here are the ones I've managed to identify so far:

- Line 84 in 18922.dat
- Line 26 in 99781.dat
- Line 17 in 2630k02.dat

From what I can tell, removing these lines should have no effect on the geometry other than removing the duplicate faces.

I’m new to LDraw, so please let me know if I’m overlooking any conventions or reasons these might be intentional.

Thanks!

An updated version of the LDraw Additional-Tools-Installer, in short ATI, containing 32-Bit-Programms.

This version comes with an update to MLCad 3.52, which fixes a bug caused by empty.dat on Win11. As a result some parts shrank to a tiny dot in all parts preview windows. Including the preview in the minifig generator.

You can download the ATI from:

LDraw.org >> Help >> Get Started >> Windows >> LDraw All-In-One-Installer

Many thanks to Mike Lachmann for fixing the bug quickly

An updated version of the LDraw All-In-One-Installer, in short AIOI, containing the LDraw Parts Library Updates from 2025-02 to 2025-06.

The AIOI supports Windows XP (Home and Pro), Windows Vista or higher (all versions). There are two installer files available: Use the 64 Bit AIOI to install all the main 64 Bit programs, while the older 32 Bit programs are offered in a separated .exe file. Please note that only the 64 Bit version contains the LDraw Parts Library. If you want to use the 32 Bit programs, it is mandatory that the library has been installed previously. The Installer will NOT run on Windows 95, 98, ME, NT Ver 4, 2000, or XP below SP2.

It contains the following changes:

* Update to Parts Library 2025-06
* Update to MLCad.ini 2025-06
* Update to Offline Parts Catalog 2025-06
