First time exploring with grasshopper, please help :)

hey guys,

for my architecture project, I am designing a hexagonal shelving unit that is flat from one side (the point of access) and extruded, with a smaller radius, on the other side. (ref image)

the issue I am having with the script is 1. finding a way to create a surface between the original hexagon and the extruded hexagon with smaller radius.

2. create triangular panels on the surface once I figure out how to create the surface between the two hexagons.

I tried using 2d truss through lunchbox and lofted that but the result is not what I want. (ref image)

simply lofting the two hexagons doesn't work, it gives me a jumbled up geometry. :/

please help!!

That GH file relies on Rhino curves. Can you upload the 3DM file with those curves, or otherwise internalize the curves in the GH file?

sorry, my bad.

If you graft two polygons that you were using for the truss you can put these straight into a loft and you'd get the surface you're after. Is there a reason you want the triangles? As the surfaces are flat I'm assuming it's an aesthetics thing? There's one way you could do it in the attached.

Thank you for your input Joe Allberry, I really appreciate it. yes the triangular panels are purely aesthetic, and with your help and David Ruttens' I now understand how to go about it, but my next challenge is to make depth cues for the triangle edges so that when I 3d print my model the triangles are visible instead of a flat surface. any suggestions?

regards,

Paresh

Simplest thing I can think of would be to use a pipes for the lines and spheres for the nodes to stop it creating gaps. There are other methods if you search for the cytoskeleton/exoskeleton conversations on here if you were looking for something a bit more blended.

It uses Kangaroo's "Remove Duplicate Lines" component to avoid doubling of geometry so you'll need that for this to work.

Here's how to make it work with Loft. I'll try to make the triangles next.

This is one way to do triangles. Not necessarily the best way...

In fact if we're hard-coding mesh triangle indices, might as well go the whole way.

hello David,

thank you very much for your help I really appreciate it. That is exactly what i wanted to achieve. my next challenge is to make depth cues for the triangle edges so that when I 3d print my model the triangles are visible instead of just a flat surface. any suggestions for that?

I intend to offset the surfaces directly in rhino for the purpose of 3d printing as well. I tried offsetting it in grasshopper but the faces are overlapping and getting more complicated.
