- looking for symmetries (can a part be cut in half or smaller pieces which can be used multiple times)
- using prims
- running some helpers in LDPE (for example Edger and Rectifier)
- closing gaps
- use "round" to get rid of too much decimal places
- flip triangle pairs and merge them to quads
- get some vertices to "ideal" values

I've used some tools to try like MeshReducer, Edger2, and Rectifier, but I haven't fully understood if the final result is correct and what i really need too do. Assuming this part is completed, I also want to add simple patterns, such as a snout and eyes. For example, the eyes consist of two black and white circles on an inclined plane.
i use for the eye on the supbart  the XY Z-Back, set the front background image, and create two circles with triangles? Afterward, I plan to cover the remaining part of the surface where the pattern should be with color 16.
is right this way?

 This software is truly challenging to understand. Would it be possible to have a video tutorial explaining the entire process of this baby kitten from start to finish?"

first of all you have to get your unprinted part right. Subfiling is good but apparently the face is not symmetrical:



You have to adjust the left side to your subs. Probably the conds will be off as well. Delete them all and regenerate them at the very end.

* There is an artefact in the nose of s01

* The is an overlap in one leg with the standard studs:

1 47 0 0 0 1 0 0 0 1 0 0 0 1 stug-3x3.dat

* LDPE complains about invisible conds but that will be automatically fixed once you delete/regenerate them

* This part has way too much detail, especially at the inside. All these:

Use the Snapping grid (near the world icon) to finetune your movements. You have to hover over the arrows until they switch to a yellow color to activate the actual movement. The vertices will only move as long as the arrows are yellow. Experiment with the selection/movement.

* "Select... -> Nothing -> Conditional lines -> ...All." All conds should be selected.
* Delete them
* "Select... -> All types. Not restoring what should be selected, will cause much trouble later, when you try to select something and apparently nothing happens.

I take for granted that you saved often and more important that you saved the various stages of the cleansing as you were moving along.



1. "Decolor part" to ease MeshReducers work.
2. "Tools... -> MeshReducer. This will take multiple passages.



Meshreducer is a fine tool but as with all automated processes, sometimes the result is a bit off. Check the colored areas.



Especially the area between the eyes looks strange and zooming in you will see that there is a looong stretched triangle. Long stretched triangles are always to be avoided, as they will give renderer (especially raytracer) a hard time, because of the time needed to calculate the anti-aliasing.

You have to delete those triangles and rebuild them from scratch.

1. "Create a new triangle..." or "Create a new quad..."

In the attached file I fixed some of the triangles and flipped some others. Try to understand why I rebuild that area and how I designed the new mesh.



Just post your s01 file.

Try also the other viewing modes and see what they do.



As I wrote above, MeshReducer is a fine tool, but not perfect. Your mesh needs further sanding. I'll post a before/after picture where I "CTRL+E" or "CTRL+W", "F" or "6" the vertices.



The criteria for merging vertices and reducing detail and complexity - especially on the inside -  was:

* How much detail has the overall part compared to the area I'm sanding?
* Do I need this detail on the inside where noone won't ever see it?

Work on all four legs, check if the stud still fits without overlap:

1 47 0 0 0 1 0 0 0 1 0 0 0 1 stud.dat

1. Select the "Line Mode" which will select lines as well as conds.
2. CRTL and select all conds to complete the circle at the base of the tail. You might switch to BFC Mode to better see the conds.
3. "Conditional Line -> Line"

On the other hand you'll find edges where conds are better suited:

2 25 5.355 -22.01 -5.976 3.753 -22.457 -4.422
2 25 3.753 -22.457 -4.422 1.954 -22.366 -3.831

* Do the opposite "Line -> Conditional Line" for those.



Edger is the perfect tool to find flaws in your part. At the bottom of the Text Editor it will list the unmatched edges. Unmatched edges are triggered by:

• T-Junk
  
• Gaps
  
• Overlap
  

* Apparently you didn't delete the looong small triangle I mentioned above between the subs. Fix also the problem in the right front leg. Switch to BFC mode to better identify it.

* De-Color and post.

3. HISTORY also belongs to the main file and should be deleted.

4. Delete the sub refs as they go to the main file and don't belong here.

* Check everything twice, fix your header, de-color once more. Save.



* Open your main file and insert all subs. Documenting them is a nice gesture for the reviewer.

* Before you save run Edger once again. (Edger is your friend - always). If it fines some conds in the middle it is fine. If some unmatched edges are found as well you've got a problem and have to back to the subs.

Browsing the net I found this, which seams much more appropriate.



1. Adjusted the background image approximately to the width of the ears, to get the basic width correct. Try to fit the eyes into the area of the subs, scale it a bit, adjust ...
My aim was fitting the image as symmetrically as possible into the subs area and at the same time get the central vertex in a hypothetical center of the eye itself. You will later see why.

2. "Add primitive -> ..LDraw primitive... -> ..Circular disc sector.. -> 4-4disc.dat

The disc isn't the pattern. It serves as a guideline to get a fine shaped circle.

3. Positioned the disc right over the vertex and increased the height a bit as the eye looks a bit higher as wide.



1. Copy and past your disc and set it aside. The next steps are all trial'n'error and you will probably need a lot of these prims 'cos your values a completely of and you need a fresh start.

2. Make sure you are always in "Primitive Mode"

3. Use the Select, Move, Rotate, Scale commands for the manipulation. The result can be seen in the Transformation matrix.

4. It could be that you need to adjust your background image once again - very, very subtle.

5. Your goal is to distort your disc in way that much of its vertices hit the boundaries of the underlying mesh.

You need just one eye. You will mirror your sub in the patternend version of the kitten. I attach my version below.

Happy fiddling

* Scale/Rotate (a tiny bit)/move the second prim 'til it reassembles the white part of the eye and at the same time its vertices become one with the underlying mesh



* Select the big prim and "Ungroup" it 'cos you cannot select prims+triangles at the same time



* You are going to calculate the intersections between the former prim and the mesh. You could do this for all triangles involved at once but your file will get messy. For the sake of not getting lost I do this vertex for vertex.

* Zoom in to the first vertex
* "Triangle Mode" and select the two triangles whose intersection you wanna calculate.
* "CSG Intersection points"



* Zoom in even further
* "Vertex Mode"

* You are interested in the vertex that is in perfect sync with the mesh of the sub. The other two should be deleted.



* Repeat this process for all vertices where you need to calculate the intersections between the prim and the mesh.
* A lot of vertices will be generated in the center. Don't care about them. Those can be casually deleted but do NOT delete any vertex of the mesh.
* The result should look like something like this.

By now other authors will say that this is all nonsense, that generating an approximation of the eye - leaving the rest to Slicer - would be sufficient. Well, my way or the highway ;-)
