I've generated a tube by sweeping along a 3D spline. I can display the curvature combs for visual reference, but I don't really understand if this corresponds to a real world curvature by varying the scroll wheel? Anyway, what I ideally require is to determine actual radius dimensions along the sweep, or at minimum, the tightest radius to confirm allowable bending. Any recommendations?
If you right click on the spline in the sketch you can pick "Show Minimum Radius" and then it will draw a yellow circle where the min radius is and give you the value.
