Normals on Ellipse

[Quickly23]

Hi,

I’ve worked out the intersection points of a set of curves with an ellipse. Now i need the normal at these points but i cant get it to work.

I’m able to do it for one point on the ellipse but not for my list of intersection points.

Could someone pls give me a hand?

Many thanks,

Stephan

connect the tB output parameters of the intersection to the t input of evaluate curve

don’t reparametrize the curve, flatten the t input

Try this: You can’t use the Normal ‘Rotate’ component to rotate a vector.
