Hello, I am very new to grasshopper and was hoping someone could help me out. I am trying to create a wavy surface but all the tutorials I have watched are based on a flat surface and I want to distort a curved surface. My thought process in Rhino was to create a sweep with different profiles. In Grasshopper I have crudely managed to create random points that I have rotated around a central point, baked them, then in rhino I have drawn a curve through these points then performed a sweep. Is there a way for grasshopper to do this to avoid me having to complete it in rhino? The first screenshot attached shows areas that I need to remain constant hence I was thinking a sweep would be the best option.
What a cheap shot at planned obsolescence by McNeel.
I see no attempt to create a surface in this GH file? There are plenty of good ways to create a wavy surface. One way would be to extrude the blue curve in your first image (which is not in the GH file?) to create a surface, then populate that surface with random points that are used to obtain surface normal vectors at those points that move the points.
don’t know if what I see on my screen is the expected result… but if the issue is going from Open Extrusion into Untrimmed surface, you can cast as Brep
file is:
I’m on Version 8 SR4 (8.4.24023.15001, 2024-01-23) ]
Loft also works instead of extrude. R8 is still broken, long after the official release. My trial version will stop working soon, which means many forum conflicts ahead.
Complain to McNeel.
