Always amazed as little forms can do in no time! :)

Add a dummy SPlit at the lateral sides to make extrusions (the fork tines).
Make extrusions on perimeters! So kill inbetwenner faces !
Separate/Join when a subdivision is made!
Close a hole with successive snaped extrusions!
(here one by one because intervals are not the same! So no possibility to use array! )



You will have a solid at the end!



Of course not yet so fluid than Rhino 7 but funny! :)

Extrude by Dir then
Orient / Line-Line / Stretch / Copy can be cool + Plane sides
can be cool for increase the volume on no regular perimeter!

Infinite possibilities of Bridge function! :)

If any questions about this funny method of subdivision inside Nurbs don't hesitate!
Thx Max Smirnov for these magic tools!

Advantage is the very few tools to learn/use! :)

- Extrude face(s) (not on the extremities)
- Scale with Points enabled
- Split on a single Edge or a face(s)... don't need to recall it, just Right Click
- Bridge only between 2 faces : careful of overlapings
( useful for replace the Extrude at the "extremities" : just Copy / Move the face then Bridge )

Show Points from the beginning, and never accept the SubDive before the final result wanted... :)

Here just a tranparent Texture of the Engine Render...

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!
