61678 and 41749/41750 overlap
#1
Looks like we need to adjust either 61678 or 41479/41750 as they currently overlap and shouldn't.

Tricky one
official parts, patterned/stickered parts, other compatibility to consider...

Probably 61678 that needs to be adjusted.

Looks like 1 pattern and 4 stickers for 61678 (plus shortcuts)

If that one changes, the similar part 39606 need the same change too.

Which part do you mean? I cannot find 39606.

Sorry. I flipped the two first digits. I mean 93606. It's the 2x4 version of 61678.

I propose to modify the top (and side chrd) of 93606/61678 using the following procedure:
- Rotate it by arcsin(20/80)=14.4775°
- scale the curve in y direction by 0.7644
- Rotate back by -14.4775°
This way we flatten the curve and follow the one of 41750. Benefit of using a mathematical procedure is that we can apply it to patterns without breaking them.
Code:

What do you think?

I think there is more to this:

It seems that 46413 and 41749 are done with 42022 in mind
45705 looks to be more in line with 61678

Do we need to change 45705 as well?

I guess so...

Any more interactions of those parts? Trying to think which other ones would be affected.

I will scan both parts tomorrow, to check the exact measurement.

Here's the overlay, looks like the 4 x 1 is closer to the original

41749/41750 are now in the PT and in need of an overhaul.

How should we continue?

I would go for an adaptation toward the curve of the 61678 (1 x 4)

There are no stickered parts in the library for 42022/41762, so also adapting those would not be too much of an impact, or did I overlook something?
