UnrollSrf + FlowAlongSrf

[petermasek]

Hi all.

I need some help. Is there a sequence of tools in Grasshopper that could replace my current workflow? I have a surface bent in both directions, and right now I’m turning it into an unrolled surface (unrollSrfUV)… then I create additional surfaces and geometry on the newly created surface (the original unrolled surface remains unchanged). Once I have that, I use “Flow Along SRF” to wrap that geometry around the base geometry.

Could you give me some advice, please?

P.S.:Actually, I need to have a live transition before and after the “flow along srf” function.

Hi peter,

Can you post images and files of what you are trying to accomplish, as well as the Rhino version you are targeting? Thanks

Sure, but it’s simple…

After FlowAlongSRF …

Very thank you … I just need some ideas on how to get started.

This is my solution:

I had to change a couple of things:

1. unrollSrf isn’t available as standard tool in Grasshopper, so not to use a plugin I opted for UVCurve (dimensions)
2. becaus of 1 the projectced geometry aren’t exactly like in your file but from my experince this way is better and gives you wider control over the results
3. becasue of 1 you have to work on the untrimmed surface (original)

Hope this help you.

thank you for now. i will try this.
