Can't Get Brep/Plane Curves to be Evaluated

[Nikita_Minin]

Hey there,

I’m trying to model the London Aquatics Center and I’m trying to get some curves generated by Brep/Plane to be evaluated. The evaluate surface command is not able to collect inputs that should work. I have uploaded some photos, please let me know if you can help or need further information!

Thank you

I keep on having problems with the vector direction of curves. For example my perp frames don’t show up. How do I change the direction of a curve or surface to get the Perp Frames aligned? Perhaps this is part of the problem

Upload the grasshopper file.

This isn’t the full file, but it has enough I think to work with.

Let me know what you think.

The message on the Evaluate Curve component is pretty clear, you didn’t supply anything to the Parameter input.
