With the last function Sscale seems we can make some many things ;)
That's a very funny method of modelisation! Thx again to Max Smirnov for its crazzy plugin!
If i have forgotten something don't hesitate!
The only default of this method is that result is like a random result about measures...
so some tests...takebacks...it's an artistic method! :)
Oh no! You have the magic function Ssplit with selection of one(s) face(s) (your image above)
Of course make a shortcut for a speedy race ;)
mine are P = SsPlit, E = Extrude, K = Subdivide, S = Sscale , B = Bridge
With only that you can make miracles! :) (I can't memorize more! :)
Here only 2 faces in the same time!
Like here all faces are splitted in the same time!
But you must select one face first then all the rest with for example the rectangle selection!
By hands will be a nightmare : drawings lines, Triming, etc...
or only one edge for "SPlit" all the volume!
Here split edge one by one (very cool to make a right Click for recall the function after a new edge selection! ;)
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! :)
