fixed- i mod vertex of supbart

I'm glad you figured out the problem was in the sub. You could obviously set the x value to 0 for all four vertices in the text editor, but I'm gonna show you a faster way to fix this kind of error.

   

1. Select "Vertex mode"
2. Select the 4 vertices which should become X=0
3. "Actions ... -> Set X/Y/Z for (selection)
4. Tick X in the dialog and confirm

   

Since you are there you should fix your title

* Choose a description which is appropriate for LDraw and not completely different from BL. The header specs are here:

https://www.ldraw.org/article/398.html

* The slash after the "s" in Name is actually a Backslash!!!

1. Place the cursor in the text editor where the part type is missing
2. Activate "Insert Objects Behind Cursor Position" or all inserts will be added at the bottom of the file in the text editor. This is also true for triangles, quads, prims ...
   Hit "Add a comment or a header entry"
3. In the dialog tick "Unofficial" and select "Subpart" from the drop-down menu.
4. You get a preview of the result
5. "Append or insert line" Based on the setting in step 2.

Your final header should look like this:

0 ~Animal Kitten Standing - Nose
0 Name: s\80686s02.dat
0 Author: Dario Fol [dariofol]
0 !LDRAW_ORG Unofficial_Subpart
0 !LICENSE Licensed under CC BY 4.0 : see CAreadme.txt

0 BFC CERTIFY CCW

Correct all header in the subs and the main part.

   

Since this is a small file I'll show you the concept about concave and convex combination of triangles

1. "Create a new line..." across the two triangles at the bottom.
2. You'll notice that the 31 - Lavender colored line is below the 4 - Red colored line.

* Rotate your part and observe that the split between these two triangles somehow point to the center of the part in prospect of the surrounding triangles. These two triangles are concave. They have to flipped so that the split point "outwards" and lines up with the red line.

* Select the two triangles
* "Actions... -> Flip / Rotate Vertices, Lines and Faces or hit the F key

There is no rule if a pair has the right orientation. You have to rotate it and watch how it shading behaves. Here's the final code after I flipped and "Rectified" the faces:

Reviewers at the PT will color the pair of triangles they feel are concave and need flipping.
