Is it possible to rotate the curvature graph or restrict its rotation in xy so that it is oriented generating something like in example A?
it is because if I use the flow command in example B the figure generates distortion; but if broken in object āAā maintains a natural flow
Hi @vikthor, is this a Rhino or Grasshopper question. Itās in the GH category, but I only see Rhino in the screenshots.
Hi @DavidRutten and @Joseph_Oster thanks
@DavidRutten I wish I could solve it with grasshopper
It was easier to explain myself with an example with geometry directly in Rhino.
the only thing that interests me is to restrict the rotation of the curve, so in the example I use the curvature graph, regardless of the heights it has along the path.
only be able to address in a direction without rotation
@Joseph_Oster
It is not what I have in mind. I will try otherwise to make myself understood; please bear with me
Imagine a reptile moving along a path, it happens that when the reptile moves along the curve it begins to rotate along it. thatās the rotation i would like to avoid.
tried to achieve a natural flow

but I want to be able to easily adapt to any 3d curve
OH! You know, I really canāt emphasize strongly enough how helpful it would have been to have your GH model from the very beginning. REALLY. Donāt need the video, the model is enough.
Flow doesnāt seem to give you any options but you could use āperp framesā aligned with vertical or horizontal to loft a cross section to make the box, then use Orient to add the pyramid thing (not shown below). Often there is no difference but sometimes maybe there is?
No code again? Iām done, ciao.
:pensando: itās really not the solution Iām looking for
Please check the attached file, I am trying to create a curve similar enough to the help curves that I have attached in the example.

Is there a way to alter the direction taken by the curvature graph in such a way that it directly affects the involved curve, and that the graph shows the new orientation of the curve?
Is the question about how to control the shape of the curve, or for a curve with a certain shape how to change what the curvature shape displays?
or for a curve with a certain shape how to change what the curvature shape displays?
exactly iām trying to change the shape of the curvature
Or do you want to alter the shape of a curve by changing the curvature graph similar to moving control points? If so I donāt think that is possible.
Unfortunately, this is how I try to manipulate the curve from that perspective, it is the cradle of the distortion of the orientation of the flow along a curve
Are you trying to build a rollercoaster?
Take a curve that would describe your path then array isoceles triangles along it. Rotate the said triangles around the point attached on the base curve according to your expectations. Then interpolate curves from each of the two corners thay are not attached to your base curve.
edit1 : F ! This is a tiny gif 
edit2 : Thank you @DavidRutten for edit 1.5 !
I can have a look in that file when Iām on my computerā¦ But I think i used Curvature component (+ some gravity equations to have the banking from the forces). This is a old and bad version though.
But for your specific question Iād use Curvature component, then move points in opposite direction of the curvature at parameterā¦ Not perfect, but thatās what first comes to my mind

But is this what you were looking for?
@vikthor hasnāt explained yet whatās wrong with what I posted above, but Iām not going to pull teeth to get answers.
