Wind turbine tube segment

Grasshopper
1

Hello,

I am working on a project where I am parameterizing wind turbine segments. I am having issues the skin (external and internal) a thickness to be solid (parametric slider).

Can anyone can help with a solution please?

Thank you

elp with this part please?

Flatten both loft outputs.
Join the three segments with Brep Join and then cap the open ends.
Subtract the inner loft from the outer loft.

I have tried what you explained but it does not work. I am not sure whther if my workflow is correct. When I start increasing the number of segment my offset surface is giving a mistake.

Thank you for your previous reply!

What does not work on your end?

This is bizarre setup:

the centre curves are duplicated therefore loft fails.

What the shift was for?

Martin’s tip solves the problem, but not with the current input.

Bizarre or not?

It just creates three individual lofts

With the individual lofts, the segments need to be joined first. Just like I wrote above. Of course if the input curves are not in pairs but four sorted circles, a single loft is sufficient.

I am kind of beginner with grasshopper so I was trying to perform with chat gpt a bit. Trying to make sure oututs and the like.
I used shift list to create segments (and use loft per segments) and also creates top and bottom per segment. I dont know how could this be part of the problem

I’ve tries tis in this script. the things is I need to create a truss panel inside and algo give the same thickness. but somehow did not work. I skipped the thickness and try to create all planar surfaces. Those are the two problems I am mainly struggling with

It is overly complicated if you loft bottom to top only.

If you needs segments, just slice the simple form afterwards.

This might be worth looking at

This is basically how a segment should look. I just been thinking on how it would work in my head and ended up there

13

This could be a solution I could try. I just started with this flow because why would be so problematic

14

I think building segment using panels (from the start) would be a better approach here, but i have troubles interpreting this image.

The imagi I’ve uploaded is like 2 tappered concentric tubes surrounded bi a panel truss

English is my fourth language I’ve learned and I still struggle with problem described by words only.

I tried to do it as you mentioned and this part works. however, I am still doubting on how to include the truss panels inside the two hollow curves.
