Quick Comparison -Subd and Artisan

Here's also a screenshot. For the sake of investigating the mesh, the smoothing slide is on 0.
Here, Subd shows triangulation, while artisan shows quadsYes, SUbD always create triangulated mesh for the sake of editing performance. Though they are created as QuadFace Tools quads - so pairs of triangles will be treated as a logical quad.
Technically, even a native planar SketchUp quad will have two triangles - at least in terms of the GPU. It's just a matter of whether you expose the sub-triangles to the end user or not.Once you are done subdividing, you can convert the instance to a plain mesh (Context Menu > SUbD > Convert to Plain Mesh) and then use QuadFace Tools to remove the triangles from planar quads:

I have fixed the geometry by removing the triangulation and by using the Quad face tools. I have also oriented each diagonal on the same direction, this helps a lot with Artisan too.
Honestly I don't exactly know which of the functions works to fix it because I have tried for a couple of times all the convert from tris to quads including the sandbox option.Making sure things are treated as QuadFace Tools quads is the key here - that two triangles share an edge that is soft+smooth and doesn't cast shadows. Then QFT and SUbD will thread them as one logical unit.
(I took screenshots of your model to visualize the results after quadifying the mesh)

Artisan would give similar results to soft&smooth" and non-soft&smooth geometry.
Now Im learning...

SubD (catmull clark subdivision) works best for quads, and quads in SU are quasi-defined by Thomthom this way "two triangles share an edge that is soft+smooth and doesn't cast shadows".
Artisan uses another subdivision algorithm and don't need quads.

plus it retains the material and UV info (haven’t fully tried this though). You will lose all materials in artisan once subdivided.
Just want to clarify a common misconception about Artisan. You CAN retain materials and UVs in Artisan, you just need to enable that feature in 'Settings'. It is not enabled by default because it results in a performance hit.

Hi, everybody. Here's my example with Artisan, texture and UV is retained.

OK. This is my little experience after several hours. Excellent tool. Sorry for the last image

One grand pig! Very fat. Reminds me, I think something from my childhood. A piggy bank that wagged its tail up and down when the coin was put in.

I had to post to another thread. SUbD examples and models.

Love that pig!

Hi, as shown below, I´ve never managed to keep any texture by using Artisan.
What is the trick to achieve your result?

... and once again AUAAA
thanks Cotty! I am ashamed 
How could I have overlooked this option?!?!?

I think the Coca Cola has the texture distorted... and I am sure is not because of the brand. Pepsi seems fine.
What would be the cause? -

I think "Coca" and "Pepsi" are same. How do you think?
Love it!
Would you mind sharing the model? I'm about to look into OpenSubdiv and it might provide some better UV mapping features. That model looks like a nice test model to experiment on.

I make a small test inspired by correspondence on Skype.
Not for holy wars just for fun.
