more on splines

[AJLynn]

Sorry to keep posting newbie questions - I'm starting to get this down but still running into trouble every once in a while. Right now I'm working on a wall in the building with the roof I posted. I'm trying to do an effect similar to the Herzog & de Meuron Signal Tower in Basel:

 

 

See how the wall is formed from sheet metal strips that twist to vary the permeability of the surface. I thought I could do that effect with a sweep NURB, using a narrow rectangle for the profile and a bezier spline for the path, and rotating the intermediate points, but that doesn't work. Using a rail spline doesn't seem to be what I want either. Any ideas? I'd like to have this be as simple to make changes to as possible since we don't have decisions on the final form yet and there are going to be multiple "twists" in each piece.

draw your profiles, or better a single line, copy two times and make a simple nurbs U-loft. now you can rotate the center line and even animate to twist like HDM. to make it a solid just apply a shell-modifier.

 

cheers

There is a rotation setting in the sweep nurbs itself. Set it to 100% to rotate once along the path spline.

Thanks, got what I wanted using the rotation modifier in the sweep nurb and lining up more than one with different rotations to get effects - not as elegant as I'd have liked, but fast and easy for sure.
