Hi there, any idea of how can i modifyone of my topography curve and so then, the rest of them modify too, so i dont have to redraw one by one all of them? iv never used grasshopper, but do i have to parameterize the curves
i guess your request only then makes sense if you have created/drawn all the topography lines yourself, or if you have derived them from geometry that you created. once you have the lines in place and are trying to modify these without having anything involved before not even grasshopper might help, at least not that i could imagine.
if you wish to work with grasshopper then you should also tag it accordingly. for rhino there would be a solution with history enabled if you have a terrain that you created from outlines and used the command contour on the geometry. then hide the surface or whatever you have made, and change the input the input curves for the terrain, as a result all the contour lines will change with a short moment of waiting since history has to update all involved curves and geometries first.
though there is a bug on my side, locking the contour to help you keep an overview results in having the contourlines follow the state of the input curves and also onto a new layer.
Thanks for the answer! when ive got my contoruns, how do i create the surface for the terrain?
We could imagine that there is a vector field that allows the transform from the initial curve to the new curve. So the Vectors non null are just on the modified part initial curve, now you can smooth that vector field with keeping the initial vectors
Something like that
Now you smooth it, here with a lower scale in order to see something
50 iterations
3000 iterations
sorry i did not see your answer earlier, to assure people get notified click on the arrow below the post you are replying to, if you press on the blue arrow you reply to the topic only.
regarding terrain: you could use patch with your input curves, loft also might work depending on how you structure the input curves, if you have two on the same level then loft will not work obviously.
