Another common varient: 1941

1941 Plate Special 1 x 1 with Hole Through Stud, 3 Bars and 3 Bar Holes

Similar to 20612. It's be around for a few years and is in at least 20 sets so should probably be modeled.

I wanted to do this quickly, but after comparing what we have and the external resources I had a chat with Philo first as it feels like a little can of worms...

Philo's 20612 is based on a LDD Mesh from Digital-Bricks

Looking at 20612 and 1941 from the BI, the location of the perpendiculat bar is one LDU lower...

How do we approach this? keep the official 20612 positions? Might be the best

If the holes are aligned, the stud will be lower

check for yourself:

Keep 20612 as it's made.
1941 is a totally different part.

...I wouldn't exactly call it totally different.

It basically only has a throughhole through the stud and an antistud, the other geometry is the same, the trhoughhole makes it more versatile

[Philippe Hurbain]

the other geometry is the same

are we sure of that?

I can say that, visually, the geometry looks completely different between the two parts to me. Functionally they may be nearly the same, but 1941 appears to have very different geometry.

If you put the file I attached like this:

Code:

1 11 0 -1 0 1 0 0 0 1 0 0 0 1 20612-db.dat
1 14 0 0 0 1 0 0 0 1 0 0 0 1 20612-bi.dat
1 9 0 8 0 1 0 0 0 1 0 0 0 1 1941.dat
1 10 0 -1 0 1 0 0 0 1 0 0 0 1 20612.dat

the perpendicular bar holes are at the same level.

this is what I mean with the same geometry. (function of the perpendicular holes)

- in 20612 you can insert the bars further in than in 1941
- 1941 hat a throughhole and an antistud.

as I got both with me, I can hardly see if there is a difference in the vertical location of those bar-holes (i.e. this 1 LDU)

And what about these assemblies where I see a 0.675 height discrepancy?
