Reference Axis - Grasshopper

Hello everyone,

I am modelling a bridge with Grasshopper and Sofistik plugin. However, the edge of the road is variable, and it is following another axis (it changes both vertically and horizontally), and this curve cannot be described by a parabola or other. I already have this curve in Grasshopper, but I don’t know how to use it for the extrusion of the cross-section along the road axis.

Any ideas or suggestions?


As far as I know this approach is not possible at the moment.
I think you have to parametrise your curve in order to consider the curve within your cross-section.

Hello Frederik,
Thank you in advance for your help. How can I parametrize this within the cross-section? Is this can be done in the JSON file?
Can you show me an example of this?

Kind regards,
Sebastian Gutierrez
