<p>Thanks for your reply and definition, David. It makes sense, and adding the [GraphMapper] works out nicely.</p>
<p>Playing off what you wrote above, I'm wondering if the [Equality] component could be used to create an applicable expression. Something along the lines of: "the more the curve bends away from the neutral axis (a curve attractor/repulse-r maybe), the greater the 'banking' of the curve." Could this be created with the [Tangent] component?</p>

<p>You may want to add a more advanced mapping from curvature to elevation than my *5 approach. I sort of suspect you're after a non-linear mapping. You'll need to insert this between the [Vector Length] component and the [Unit Z] component. It could be a GraphMapper, or an expression or....</p>
