Hi, So I have a wavey surface with an attractor and a sine wave to move control points and make a surface out of them. That’s all good, however I would like to keep the edges of my surface straight (= flat). ondulating surface_for review.gh (11.6 KB) [Annotation 2020-02-25 133550] [Canvas at 13;3…

thanks @Joseph_Oster for all the resources, I’ll check them out and see how I can apply the to mine.

I think i get the logic, not sure how to build it in components yet but I will give it a go. thanks @Dani_Abalde

Similar to this: [image] Make Field normalize at boundary edge Hi All, See the image below. I have a panel that has a straight border on all sides. I want to add several point charges to the field of points. But, regardles… [samplefile_2016Aug9a] Quite difficu…

The first example I mentioned is the best one. A quick copy/paste into your code: [undulating_surface_2020Feb25a] undulating_surface_2020Feb25a.gh (18.6 KB)

thanks, that’s pretty close! I’ll check the other links and of course the forum search (just sometimes the keywords aren’t obvious for me)

“pretty close”? How is it the slightest bit different from exactly what you asked for? Forget about the forum search feature, it’s nearly useless compared to Google: “rhino grasshopper whatever” https://www.google.com/search?q=rhino+grasshopper+surface+from+points+decay+damp+effect+along+edges+os…

Sorry, it is what i asked for , didn’t mean to sound unappreciative! I just want to tweak it to make sure it doesn’t look like there’s a flat rectangular frame around the wave, i’m working on it.

It’s not about being appreciated, it’s about what you asked for: I would like to keep the edges of my surface straight (= flat). Increase the maximum for the ‘range’ slider and bump it’s value up to ~80+? [undulating_surface_2020Feb25a2]

Interesting use of Pull component, @Joseph_Oster … i’ve actually never used it and i see its potential now… i feel noob. There is always something to learn. Can I ask you why you used Round and Eval components? Using the result of the division to the mapper seems to give the same results…

Fillet the perimeter curve and ignore points outside of it?
