I am trying to add edge loops along the length of the object.
But somehow Fusion subdivides three of the selected sides as intended and the 4rth one in the opposite direction.
T-Spline subdivision oddity (bug ?)
Uhhm ok what happened here? Not sure.
You mentioned some issues with TS. I further elaborated on that given the fact that I am with TS since it came out
and having observed that in the field this technology got very accepted and widely used.
However sub-d is not sub-d. So I did a quick comparison with highlighting some negative parts
but in majority wise more positive parts about TS.
So for sure not Fusion bashing on my side.
This was more a reflection on some of your comments about TS in general.

"I know T-Splines since it was in Maya then Rhino. It is a fantastic tool but the speed and inability to extrude edges only faces makes it often not very usable in my point of view"
I'm not sure who told you that you can't extrude edges but they were mistaken......
If you build your T-Spline models completely inside of Fusion performance is pretty good. I have some pretty complex models that perform perfectly fine.

grrr English ...
I did not mean extrude an edge out as a face - I meant extrude a cv into an edge.
this limitation is often for me a roadblock making certain adjustments much slower in TS than in any other poly modeler

Show me what you mean in an app that has this ability. I'm curious.

@PhilProcarioJr Never used Maya Modo Blender C4D and others?
TS is based on faces because in the end the TS face will be converted into a BREP.
TS has it's origin also in Maya that is also a little stiff in the way how it treats vertices edges and faces.
So the difference is how easy you can model a wireframe you then mesh (add faces) compared to being
main only able to extrude edges into faces or faces into new faces.
It is a question of a workflow. In the end you can get the same probably done - question is how fast.
Specifically when you want to change the topology and reroute edge flows this will show the impact then.

I see what your getting at, but knowing what I do about T-Splines I can see new users trashing their meshes constantly working that way.
But the points you bring up here are exactly why I use sketches to build my T-Splines and if I am just testing forms I model in Maya or Lightwave and bring the meshes into Fusion and convert them.

I assumed my post was self evidenced. @cekuhnen and his clear explanations, his helpful youtube vids, and basically argumentative comments make me want to learn more from him. Especially how he thinks as a designer. You post made him share his knowledge herte and that's why I commented.
That I am perfectly fine with and enjoy these discussions. However, I've seen a number of threads that started with this good intention take a turn for the worse.
That I'd like to prevent!
My comment was not directed an any specific post or person and I enjoy comparisons for the purpose of education and learning. But you knew that already 😉
@PhilProcarioJr TS east everything fine as long as you feed it good quality mesh. It doesn't really matter where it is created in.
however I have to say modifying mesh with exploring different topology layouts is not something TS is very good at.
and the lack of custom orientations and such just makes the sub-d like modeling in fusion less flexible and controllable than actually blender.
actually the main reason I use blender is not because it is free but because it has modifiers is object based and can save custom orientations. Maya is also object based but has no modifiers or custom orientation stuff.
lightwave I don't know have not used it since 2001.
fusion is not object based and cannot save custom 3D widget orientations.
the only advantage modeling wise fusion has where it trumps seriously everything else is the ability to insert loop cuts like isoprams on a NURBS surface
adjusting the rest of the mesh afterwards.

Maya has both modifiers and custom orientations and it has Mel scripts thousands of them.......

I know what Modifiers are (in Blender) and make frequent use of them. However I am not familiar wit the term "custom orientetions" .
Could you elaborate ?
IT allows you to put your transform, scale and rotate widget along any edge, face or vertex. It can be constrained to normals too for precise manipulation of faces, edges and vertices.

Custom Transformations (sorry used the wrong term grrr bad English again)

Where and since when does Maya has modifiers like Blender or Max? I just worked in Maya today ?!
Blender also has a dramatic set of python scripts for modeling tools UI as well ...
Maya traditionally makes use of the design history into which the idea of modifiers in that way like in Max Blender does not fit in well.
Am I missing something?

All over the app, some are under animation, some polygon set.
The real power of Maya lies in the Mel scripts and node editor. All Maya users know that.
Stuff like this:

Ahhh...prego. That I understand.
The beginnigs of that are in Fusion 360 as well, if I understand the teminlogy correctly. You can select a face, change the manipulator to "Normal" and then move the face along it's normal direction.
You expect them all to just be part of the app but the community has been making modifiers for years....
Phil Procario Jr.

I think you are referring to how Maya structures internally the data in the node editor.
Maya follows a somewhat different approach than Max or Blender.
Maya is more following the way how Houdini does it. While Modo and also Blender jump onto the node wagon as well.
Generative modeling is interesting and has many benefits it can also make it a lot more complex to deal with.
Just look the amount of data points Maya creates for a cube.
There are also equally thousands of add-ons for Blender and Modo - I don't expect everything build in.
However hard coded functions trump scripted functions specifically when the mesh manipulation gets bigger.
I would still say that Max Blender is close to the feature modeling philosophy Fusion has than actually Maya.

or here another example of the simplicity in Blender and how Maya structures the data entry modifications via commands (bevel - boolean)
@PhilProcarioJr I have some brain problems today ahahaha.
So basically what I meant with modifiers is a UI that allows a workflow to quickly add functions or turn them off without much work.
As stiff as the modifier stack is one mouse swipe and many eyes are off for the exporter.
Make a python script and turn off all sub modifiers if needed since mirror and such I often use and want to export.
So yes Maya has modifiers if one wants to say so - I was more referring to the way how you can design in Blender because it is closer to Fusion that Maya is to Fusion.
However I am curious how they will do the modifier nodes and if that turns into a Grasshopper for Blender.
