Hi guys - I am trying to recreate a curved surface similar to the one shown in the picture.

http://www.schtschurdesign.com/roof.jpg

I tried the bezier-nurbs but it doesn't react quite stretchy enough - as a stretchy fabric would in reality when put under tension like that. Can someone help a CINEMA 4D amateur? Thanks

Hallo Leute - ich habe versucht eine gekrümmte Fläche zu erzeugen, ähnlich der in dem Bild.
Bisher habe ich mir am Bezier-Nurbs die Zähne ausgebissen, aber es reagiert nicht so wie ein elastisches Gewebe es tun würde, wenn es dieserart gespannt wird. Kann jemand einem CINEMA 4D Amateur helfen? Vielen Dank.

the bezier nurbs are not eaxatly nice.... especially if you come from another nurbs modeller like studio tools or rhino....

so being inC4D don´t trxy to achieve a saddle with bezier nurbs...

Insted you should forget about what you learned form your collegues about nurbs moddeling and solve the problem with hypernurbs...

take a look at the atache jpgs...

1)simply take a planar surface and reduce te amount of width an d higth segments to three.

2)next take a hypernurbs object and drop your planar surface into it (in the object manager).

3)now you have to convert your planar surface into an editable object (

4)switch to point edit mode and pick one of the cv´s and pull it.... get an Idea?

that helped : ) playing around with hypernurbs right now. The link with the audi-tutorial was great too.

any time....!

... but you should not use hypernurbs to do 3D models that will go into industrial production (spritzguß etc.) , they are nice but not really precise... For taht you will have to go back to nurbs.

Check out Jurgen Meier's Formula Site here. (http://www.3d-meier.de/)

"Simple" :eek: plug-ins for just about every surface you can think of.
Look in the downloads for the Para 8 zip.

Just place the expanded folder in C4D plugins directory and access from the main plug-in menu.

Have fun, Al.

Rantin Al, where is the Downloads section you mention is at Jurgen Meier's site? I saw mention of download in the Plugins section but, that's all. And, no Para 8 zip. Thx.

that is really cool stuff. thanx rantin AI.
----the download for the plugins are sometimes hidden in the tutorials.

Try this. (http://www.3d-meier.de/tut3/plugins/Para-8.ZIP) It's in what I assume to be the parametric shapes subsection (http://www.3d-meier.de/tut3/Seite0.html) of the plugins section. I don't speak German though so no doubt you'll have a much easier time navigating the site than me.
