Measured values!

BL keyword should be 3070pb407, Rebrickable 3070bpr0060 and Brickowl 185072

Corrected incorrect keywords

Comment:
Attempt to correct keywords

I checked it:
Keyword "Brickowl 118433" was correct!!!
Please correct it.

Actually no, the correct keyword is the one next to BOID on this page: https://www.brickowl.com/catalog/lego-tile-1-x-1-with-black-square-with-cut-corner-with-groove-3070-118433

There is a vertex mismatch here:
2 24 9.2 0 9.2263 9.2 0 9.2

Also 2 T-Junctions at
-1.25 0 -9.2
-9.2 0 -1.25

OK!
BOID: Good to know!
Can you please also check the Brickowl Keywords in part 3070bp1v.dat and 3068bp1g.dat.
Thanks

To give you some hints about how to solve the raised issues.
For vertex mismatch, simply replace "9.2 0 9.2263" by "9.2 0 9.2"

For the T-Js if you use LDPE, select the vertex -9.2 0 -1.25 and select "Actions..." then "Merge to nearest edge and split"
Do the same with the second vertex

Then apply rectifier to merge triangles in quads: select "Tools..." then "Rectifier"

Your code should look like this after:

1 16 0 0 0 1 0 0 0 1 0 0 0 1 s\3070bs01.dat
3 16 -9.2 0 -1.25 -9.2 0 -9.2 -1.25 0 -9.2
4 0 -9.2 0 9.2 -9.2 0 -1.25 -1.25 0 -9.2 9.2 0 9.2
3 0 -1.25 0 -9.2 9.2 0 -9.2 9.2 0 9.2

3 16 -1.25 0 -9.2 -9.2 0 -9.2 -10 0 -10
4 16 9.2 0 -9.2 -1.25 0 -9.2 -10 0 -10 10 0 -10
4 16 -10 0 10 -10 0 -10 -9.2 0 -1.25 -9.2 0 9.2
3 16 -10 0 -10 -9.2 0 -9.2 -9.2 0 -1.25
4 16 10 0 10 9.2 0 9.2 9.2 0 -9.2 10 0 -10
4 16 -10 0 10 -9.2 0 9.2 9.2 0 9.2 10 0 10

It's a good practice to use the following tools before submitting a part:
1. Edger2 to detect mismatches: "Tools...", "Edger2", select "Unmatched edges only", it will add red lines if there is a mismatch
2. TJunctionFinder to detect T-Junctions: "Tools...", "TJunctionFinder", it will highlight vertices in red and if they are not on an edge they usually should be fixed
3. Rectifier to reduce number of lines in code: "Tools...", "Rectifier", it will let you know if some triangles were automatically merged to quads

Keywords are correct in parts 3070bp1v.dat and 3068bp1g.dat. I certified both.

By the way for Edger2, you can change scope to file only otherwise it might detect issues that are not in your pattern.

This is my first more complex part.
But it’s still too complicated for me, as I’ve only used MLCAD.
If you’re interested, please modify the part – under your own name if possible.
Thanks!

OK I've updated it and put an history meta with my nametag

I encourage you to try LDPE (https://nilsschmidt1337.github.io/ldparteditor/) for part design, you can also try LDPC (https://sourceforge.net/projects/ldpattern/) for creating pattern from an image
There are some interesting available resources about how to use them, also some guidelines on the LDraw forum. A good guide is in French but could be translated with AI: https://jc-tchang.philohome.com/manuel/LDPartEditor.htm and https://jc-tchang.philohome.com/manuel/LPC_a.htm

Thank you very much for your suggestions and your goodwill!
