SubD examples and models
-
Yea, due to how the SketchUp API is - SUbD have to create entities for the subdivision. At some point during development I had a small polygon optimisation in that coplanar quads was not triangulated. But that turned out to be bad for performance when doing stuff like adjusting creasins - as SketchUp's Auto-fold have too much overhead when it kicks in. Also, in order to keep the subdivided entities in sync with the control mesh I cannot omit entities.
So as things are now you would have to optimise the subdivided mesh yourself once you are confident you won't need the control mesh any more.
Ideally I wish I could hook directly into the viewport - intercept how instances were drawn. But alas, that's not possible with the current API.

its been my practice to subdivide, and yes exploding at times, quadifying autofolded faces (takes a long time dealing with the diagonals).. It can be a pain with complicated meshes
. .. Even with perfectly done quads can all of a sudden triagulate when you toggle subd.I wish autofold can be totally disabled..and wish loops can be moved by dragging instead of adding and removing...
-
Would it be possible to have a tool similar to crease, where you select two loops and SUbD doesn’t subdivide between those points?
Thinking about it, that sounds almost impossible to implement....just throwing it out there.

(Note that quads from SUbD's process will be triangulated internally. But you can use QFT to toggle off triangulation of coplanar faces.

AutoFold cannot be disabled because it kicks in when a planar face is transformed such that the points are no longer planar. There is no way around that
I second your wish for better loop adjustment control. A while back I did start on experimenting with better tools for that. Not complete, but there is an Offset Loop tool in latest QFT. (Though that's only for inserting new ones. Being able to move existing ones would be nice.)

SUbD is using OpenSubdiv for the subdivision process - I don't have that kind of control Also the algorithm wouldn't be able to cope with exceptions like that.

I thought as much. Since no two meshes will be the same, it probably means you would need some kind of AI to interpret how something is subdivided.
-
Yea, it would be too complex to code understanding of such asymmetric mesh I'm afraid.

I saw a lesson on modeling a car rim in a blender. I decided to repeat it in a SketchUp.
-
Congratulations! - this is a clean and accurate work, a very complex shape and nice as well! 
could you please show the raw geometry as well? -

Very nice! I'm happy to hear that workflow from other software packages could be transferred into SketchUp.

Really cool timelapse!
I see you have the same issues as me with autofolds and mirrors (delete, remirror, redelete, reremirror, etc.). And to flatten faces you use scale? -
An old and popular German board game
"Mensch ärgere Dich nicht"
A not so complicated SubD task - I know
just a little Saturday afternoon exercise
(below I share the step by step model of the cube at least)
-
We call it "Ludo"
-
thanks fpr that info Thomas & sorry for the German claim - I thought it was like this -
I don't doubt it's of German origin. But I found it amusing that the titles were so different
Though... I don't quite "get" the German name... -
Again a very nice illustration! The virtual representation makes me want to play the game "brett"-hard and real again.

just a silly mushroom for now..
i've a bunch of nice test model from beta which way are too heavy for sharing here i don't know if thomthom is setting a gallery or something for that..

Hi panixia, are those mushrooms 'infected'

there is always something to learn actually, Ludo found its way to here over England (named "Ludo" there as well) and came from India original. Our tiltle "Mensch ärgere Dich nicht" means slomething like ""People don't tease you" or "Man, don´t get annoyed/enraged" which is a funny title because the man on the box cover is very annoyed obviously @faust07 said:

Thank you Faust and yes you're right - now the right season for this kind of games is starting! - very real, analog "Brett" hard
