Grasshopper: Triangulated Facade

Hi everyone,

I’m currently working on a project for an architecture studio where we are learning Grasshopper and parametric modelling. My design is a tower with a triangulated exoskeleton/space-frame facade. The form tapers and shifts as it goes up, so the outer structure is irregular.

So far, I was able to create the basic outline of the facade along with a core and floor plates. I have started by creating a rough model of my design, and then turned that into a 3d form using the convex hull 3d, and now I want to triangulate my facade to look like this.

I am very new to grasshopper, so I am not sure how I can turn the output from the 3d component into points like this.

I would truly appreciate any help and guidance on this matter.

Best Regards.

Does not look like convex hull 3d to me

I think you should figure out your shape first, because right now i am not sure what should be even done here

Sorry about the confusion. I organized my script more clearly.

So this is the part that I was talking about. I have the hull3D as my main facade shape; it looks like this, where it is kind of made up of many triangles.

What I am trying to do now is to make the facade of each triangle look like the image I attached earlier. I understand that it will not be the same, as my facade is made up of triangles instead of squares, but I am trying to get as close as possible.

As you can see in the first picture I added, I tried finding the three outer points that make up each triangle, and the midpoint, which I offset from the original curve, but when I try to connect them, each midpoint connects to all the other points, rather than just the three points from the adjacent triangle.

I am not sure what I did wrong, so I am asking for help to fix this issue.

Thank you for your help, I just have one more question.

So in this picture, I highlighted what I had as my original facade shape in red, and the offset in blue. I want to turn it into a surface as I want it to be my new facade, but it is not working with me. I am not sure what the problem is and I would appreciate your guidance on this.

Thank you so much for your time!

If I understood your request correctly.

Yes! Thank you so much!

I want to make the facade more interesting, so I was thinking of making something like this.

All the tutorials I found on this used a plug-in. Is it possible to do it without one?

Thank you again for your help. I really appreciate it!
