Chamfered cube with equal edges

[Kejun]

Hi all,
I’m trying to model a Chamfered Cube with all equal edge lengths(like pics) in Rhino or Grasshopper.
Any idea how to approach this?
Thanks!

Install the Rhinopolyhedra plugin from the package manager, restart Rhino, and run the command polyhedron. Pick the polyhedron you want.

Thank you Jeremy!

What a burn

I was going to mention Rhino Polyhedra and this GH code that uses it, which I belatedly posted in August, 2024 (original was done in October, 2022):

Finding "normal" direction at intersection of a polyhedron

I am stunned that I didn’t post it two years ago but can’t find it on the forum RhinoPolyhedra_2022Oct17a.gh (42.0 KB) P.S. I see this when trying to run it in R8: [missing] So I tried ‘Download and Install’, perhaps for the first time, and get this: [missing2] I probably got it here but don’t see an R8 version? Paging Dale Fugier (@dale ?) https://www.food4rhino.com/en/app/rhinopolyhedra P.P.S. They appear for me here in R7: [polyhedra]

But today I decided to try a geometric construction approach and came up with this:

Chamfered Cube_2025May8a.gh (19.0 KB)

This requires adjusting the ‘Parameter’ slider (blue group, zero to one) to minimize the value in the text panel below it. It’s interesting even when the text panel value is not minimized.

Hi Joseph -

It looks like the OP double-posted and the other one was deleted. The pains of double-posting…

On that page, should your duplicate post of this one be merged in this thread?

The same thing happened to me less than two weeks ago:

Voronoi prism

ARGHH @jordan_ali - I was working on the thread you deleted and have code to share. I kept some of your code (not shown in the image below) and copied some code I posted this morning in another thread. I could say more but won’t bother. Oh, it works in R8 but fails in R7. [voronoi prism_2025Apr26a] voronoi prism_2025Apr26a.gh (28.7 KB) [voronoi prism_2025Apr26a2]

In this case, I searched and found this thread but saw it isn’t in the GH category so my reply here would be invisible to the GH community. That’s why I created a new thread and copied my reply.

It’s very disconcerting to spend time working on GH code, only to find a thread missing. I’m not sure of the effect of merging threads in this case? Seems to me that duplicate threads (as is) are more likely to be found, eh? Thanks.
