I'm not familiar with tame polyhedra. What's the idea behind that? Have you found that three coplanar edges at a vertex comes up a lot? And vertex-transitive faces. Hmm, wouldn't that limit it to regular faces? Maybe you can post an example or two? You can click the "Add image to post" link under th...

Both good ideas. Might be a while before I can look into adding them, but I'll add them to the to-do list.

Thanks!

Most base models should have mirror symmetry already though, right?

Yes many do, and many don't. Models like the snub cube, or compound of five tetrahedra have lots of rotational symmetry, but no mirror symmetry.

Hi Robin, I don't know where you saw the "mu" variable. You can find "Symmetry Group" in the glossary here: https://www.software3d.com/Glossary.php#symgroup It's just the collection of symmetries that an object has, eg reflection in a plane, or rotation around an axis. All I meant was to start with ...

You want to combine compounds that already have the same symmetry group, then they should be aligned.

Before putting them into a memory slot, make sure they're all the same scale by setting "Scale->Base Polyhedron Radius" to the same value for each.

I think I just called them A and B at random. They may have more formal names.

14 cubes? They couldn't all fit into the symmetry group the same way.

Stella has compounds of 6 and 8 cubes in its library. You can blend these together (make sure the scales match!) to make a compound of 14 cubes:

Looks to be very well made. Well done!

Yes you can find this in Stella at "Stella Library->Compounds->Cubes 10 B"

Looks great! And a great example for using such a method.

Late reply, but I haven't been active on this forum so much (forgat checking actively) Anyway.. The answer is: yes, I did. I made some models of polychora. I use plastic overhead sheets, on which I printed a little bit of colour. One result is here: https://i.postimg.cc/TLq2QptS/Rect5-Cell.jpg Here...

Fantastic model Marcel!

I wasn't there and haven't visited the Bridges Conference for quite some years. Not even the one in Sweden (where I live). During that time I was hiking in the Swedish mountains up in the North. Next year's Bridges is in Finland again, and I hope I can be there. Nice to see your models, Robert! Sor...

Never seen this one. That is an awesome model, Robert! Is it still in one piece?

Pieces pop out easily if you try to operate it, but it's easy enough to put them back in (hopefully the right way around!)

Thanks Marcel.

The link still works for me. Try it again maybe? Does it work for others?
