I have a zig-zag figure I want to import and manipulate in Blender, preferably on a segment-by-segment basis.
The canonical method for doing "line art" in Blender appears to be to create a curve object then, in the Properties, crank up the Bevel Depth to a suitable value. The problem is that, for "curves" having hard, acute angles, you end up with a very thin, distorted shape.
Here's an example curve. All handles are set as vectors:
Here's the same curve with a bevel applied. Note how the generated tube is flattened, making it nearly invisible when viewed along the Z-axis. The sharper the angles, the thinner the resulting tube:
I'd like uniform "thickness" no matter what angle I view it from (particularly along the Z-axis). How can I best achieve this?
