Full Version: Bend ?
From: Lewis3D
Hi,
I wonder is there a way to Bend (term from polygonal modeling) part of mesh ? I have built in model which more or less looks like letter "u" but it's not correct angle so i'd like to select one side of model and then bend it from picked point/center axis some amount ? Is that possible i MOI or i need to remodel all in that shape ?
Thanks

Not stritcly a Bend but maybe the function Flow can make something for you...

Thanks for reply Pilou,
I tried Flow but couldn't get what i want with flow/deform. Either i don't understand how it works or thats not possible with that tool :(.
Basically i want to keep my object shape (not flatten/deform it in all axis) but just bend one part of "U" letter side.
Something like this (in polygons)
stage 1

end result

so i used rotate/bend falloff tool so i can bend/rotate form picked point and i can bend more or less in certaia areas with falloff.

Hi Lewis, it looks like Flow could work, however you can't use it only on a part of an object it is for warping an entire object.
So you would want to make an initial "backbone curve" running down the middle of your entire object and then make a new full length backbone curve for your target.
If you can post your .3dm model file I can see if it's feasible or not, if you want to keep it private you can e-mail it to me at

Thanks for Help Michael, I've sorted it by a workaround, i've cut/trimmed section of my object near the bottom of "U" and then moved/rotated slightly that part and then recreated area between with blend tool. It's not perfect (i have small bulge whatever settings i use) but it's gonna "pass" on render so all good for now :).
Is Bend tool or rotate with Falloff something NURBS/MOI can even have (in future) ?

Hi Lewis,
re:
> Is Bend tool or rotate with Falloff something NURBS/MOI can even have (in future) ?
No, not really, it's not a good fit with NURBS because of how NURBS surfaces have "underlying surfaces" with trim curves on them. The edges where 2 NURBS faces meet up are often times not a natural surface edge but instead a trim curve.
It's a much different structure than a polygon modeler where all polygons share vertices between faces.
There is some description of how trim curves work here:
