Shaping a cylinder - interesting technique
-
ha, looks like a glitch. i can hear the gears turning, it wouldn't surprise me if someone can pervert this into a bend ruby.

The unexpected depts of SketchUp!
This 'feature' has always been there, but hardly anyone ever payed any attention to it....untill now.
It's fun, interesting and intriguing at the same time.
I have been playing with it for hours and created unexpected shapes and forms within minutes.
It took me some time to really 'get' the tricks shown in all of KitoRaub's videos, I replayed them a couple of times, but in fact the trick is just adding a coherent, simple, sticking, visible geometry to a 3d shape and manipulating just that geometry with standard SU functions. No rubies needed, just simple SU.
The videos show a bit of perpendicular rotation and scaling of the selection, but I have already found out it is not limited to these. More basic SU functionality can be used and combinations result in very unexpected free formed shapes.
The only thing now is to learn how to control the results of a deformation: what happens and why?
Try and error will be the road to go, but I have already found a new and easy way to create some shapes which took me qiute a hard time, untill now.
Thanks Watkins for your finding. -
New toy! Yummy...

That method with selecting a line along the length of a segmented tube, using the protractor to bend it... what on earth is going on here? I don't understand. I see it working, but I don't understand. Though, somewhat unpredictable, it's very cool.

Maybe like this?
As the spiral line is inside each little "squares" (hidden geometry) and these are "unbreakable" all must follow!

pilou, thomas is talking about a separate techinique
watch this and please tell me what is happening.

Could this technique be made into a ruby?
Following what I see in the youtube (using the auxiliary spiral), this could be done, right?A ruby that would model the spiral for you and make the scaling behave as described in this thread would be wonderful.

Harnessing it into something more controllable... hmmm..

Maybe this little image can explicit that
No magic inside, it's totally normal! (click image if scrollbars)It's like escarpolette (seesaw)
Ground don't move!

Just stick to the standard 640x480 size and you'll get no scrollbars.
-
pilou, it works with no bottom as well! you may have something with the triangle thought but it would be the triangle nearest to the selected edges that would be effecting the shape not the ones on the opposite flat side.
-
Yep but these are fixed too!
-
But how come it only grows?

Hm... Fragonard...
Good taste, Pilou (I think I'd better go back to teach art history ) -

But i was under with 547*358

Only grow? No grow and ungrow!
Because face arcs' side are fixed on their "bases" and make "pivot"
All up mesh is free to deform!See first second of that
(second 10 to second 15)

here's a variation which keeps the hidden line straight during the rotation and allows the base to move..
explode the arc then weld the segements together prior to building the base..

just click on the picture and you won't have to scroll.

Ah! My post is gone.
...Now a shorter rewrite...
I think what's happening, and maybe what Pilou's trying to say, is that the ends of the arcs are stationary, and the arc has to stay and arc, and therefore the area selected can't rotate, because it can't deform the arc. So you're trying to rotate something that can't be rotated. I don't know exactly why it expands the arc, maybe it's trying too hard to have it rotate, and the only place for it to move is up.
