Possible duplicate faces in some part files - Alan Zhu - 2025-07-22
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!

Welcome to LDraw. I checked 18922 and indeed lines 84 and 85 are superfluous. You can now edit the file, add a HISTORY line describing the correction, and upload the corrected file to the Parts Tracker. When uploading, make sure to check the 'official file fix' check box.
