@Cotty: Thanks for your reply! Perhaps I'm missing something in there, but in using your solution, I simply end up hiding the lines rather than fixing the geometry.

@Gaieus: I'd never used the sandbox tools before; I'm quickly starting to realize how useful they can be. Unfortunately, it seems like some of the more critical lines cannot be targeted by "Flip Edges." Is there a reason for this? I seem to get so close to fixing my problem with this.

@Peter: Going through that thread helped me understand the importance of proper triangulation. Embarrassing to admit, but I had never known about the "show hidden geometry" option before now. I can properly triangulate the space between my curves when they're on a flat Z plane, but I run into a problem. When I try to raise one end of the shape after it's been triangulated, it only raises the very last lines and the immediately connected triangles. How can I smoothly slope the whole shape? Also, as far as realism goes, this is for a project that isn't steeped in real architecture, so a little bit of silliness is allowed.

Hi everyone,

I'm trying to build a simple, enclosed ramp/u-turn kind of hallway. In order to do so, I use the curve drawing tool to create some semi-circles. Once I have the hallway as I like it on the same Z-plane, I select the lines and surfaces at one end, and raise them up along the Z. The result is almost as I want it, except for some strange breaks in the faces on the lower side of the curve. The picture attached should help illustrate my problem.

The circle areas are problematic. Notice that the breaks in the surface to do occur on the "left" side. If I try lowering the right instead of raising the left, the same thing happens in the same place...

I've tried increasing the segments per semi-circle, along with a few other attempts, but nothing seems to get rid of that little anomaly. Any tips?

Thanks!
