Many thanks Pilou for your fantastic inspirations....great work !!!
But would you like to post some kind of "how to basic tutorial - as a step by step cook-book" for all the un-initiated noobs ?
That would realy by a mind-opener ??? Big thanks + good luck to you
Best wishes

In fact that is very simple! :)

The volume must be without internal faces!!!

This follow is the general case who always works! The Bridge function between 2 separated faces!

In this specific case the Extrude will also works because faces are not on the "extremities"
and not touch between them !
Box on the left don't work because Top/ Bottom face are too complex for the Plugin!
You must split it first! With any method but without internal faces! Here there is a new building :)
Use of the SsPlit function is of course used!





Here following Subdivision after Extrude will not work!
Because there are no more "triming faces"!

---

Hey Sub-D Master Pilou, thank you so much for sharing your insights !!

---

In case of 2 neighbour (or more) different faces - Will works with the volume's faces extremities! ;)

A possible method (the funny game is to find the more speedy effective one! ;)
- Select & Copy Move the 2 faces
- Delete original (easy because yet selected)
- Select Perimeter (careful to not select the vertical middle edge(s) !!! )
- Extrude WITHOUT Cap Ends!!!
- Join All
- SubDivide



Of course can be multiple if you take the same length of Extrude! ;)
(there is an optic effect of record, extrude goes from faces to piece as post above)

---

And Move Points is always possible!



And of course the Sscale!

---

Just use 2 Steps of subdivision (first plane - Extrusion) then extrude the faces!

I am always amazed by the voluptuous result in no time! :)

---

About history after a Mirror : seems Move & Sscale work ! (object or points)
Psplit, Extrude of face(s), Bridge of 2 faces of Original don't work for the moment!

For make an history of a mirrored object
- Mirror Object Original
- Select mirrored Object
- History Enable Update
- Modify Original! :)

---

Multiply an object by Array for unic pasted volume

- Just kill the 2 "faces jonction extremities"
- Use Array
- Recreate the 2 "faces jonction extremities" of the complete object
- Join All
- SubDivide

---

So smooth ;)

---

Piles - use of Bridge for close volumes!

---

Beautiful! (and the tuts are awesome too)

---

Thx...try it!

it's a true pleasure to make a speedy form then render it! (mine is the free Simlab Composer Lite ;) Max 1920*1080

And a cool change mind in these darkness confined times!

---

And you will see that Subdivision modeling is different than pure Nurbs because you don't know exactly what will be the result!

It's always a surprise when you press the Subdivision's button who transform boxes in voluptuous surfaces! :)

Maybe more artistic filling against mechanical one! ;)

---

This is an interesting discussion and I want share my experience in this field, I made a few experiment and I understood how modelling suddiv for nurbs conversion with moi3d.

---

A new process in the SudDive Tool Box ;)

Project a curve to a complex volume (yet well working for subdive)
Trim
Kill Curve(s)
Join
that all! :)
PS Extrude can't work because face(s) are not in middle of surfaces!
So Copy Move one face(s) then "Bridge" one to one ! Copy / Move Faces can be Multiple!

---

Always funny easy thing for make improbable objects! :)

---

About SUbDivision in Moi ! We can project an object subdivided (finalized or not) on another for deform it! (here on a Sphere )

---

Flow function can be practical for SUbDIve!
Here a cube was projected on a Sphere...of course as always imagination must be large for predict the result!

---

The cutting line method shown above is significantly slower than cutting from a segment!

But indispensable if you want an oblique cut!

---

Some minutes of the days :)
