If you are looking for a horizontal frame at specific points along a reparameterized curve (i.e. 0.0, 0.5, 1.0), you can use Horizontal Frame, reparameterizing the curve input and then inputting the values between 0-1.
Alternatively you can use it with something like Curve Closest Point. Curve Closest point outputs the curve parameter (t) at the point, which you can then input into the Horizontal Frame Component (dont reparameterize in this instance).
thank you for reply my question.
I already vertical points on curve.
afterthen, I made a square structure but it is’t same direction on horizontal frame.
If you know fix ways?
That’s the same method I used. In the file I also showed a simpler option to get to get to this goal.
