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
