So the dual property, the property we'd find in the faceting, would be a vertex where two or more faces meet that lie in the same plane.

I guess it would be possible, but no there's no automated way to skip those at the moment.

Stellations in Stella are found via combinations of stellation cells, and consist of only externally accessible faces (no hidden parts of faces). So it's not aware about how or whether facelets in the same plane can be combined into larger faces. So it's not good for finding isohedra. There are some...

I can replicate the issue. The spring relaxation system is used to generate these, so I'm not surprised there are limits on it. I would need to calculate the coordinates explicitly instead. Some day I'll look into it. For now I have a lot to do to get Stella back into a releasable state, but I'll ge...

Although I added features to Stella to make them easy to find, I unfortunately never got around to publishing my results. But polyart on this forum is getting a paper published about them soon. I'll direct him to this thread, in case he hasn't seen it already. They can be found as facetings of isogo...

If you have Great Stella or Stella4D, then they can be found in the library, in the Bruckner folder: https://i.postimg.cc/9fmD1HN2/image.png And since Stella shows you the dual as well, and nobles are all duals of other nobles, you get two at once: https://i.postimg.cc/MG1SF9XY/image.png You'll even...

There isn't really a page of default options anywhere, but you may be able to restore some of it by saving a default file. Use "File->Save Default Scene". Whatever scene you save there will automatically be reloaded when you restart the program, along with whatever settings were saved with that scen...

Hi John, Yep that can be done. From the menu, enable "Display->Show Vertex Angles" Select a vertex (Either Shift+Left-click, or double-click on a vertex) It will show angles related to that vertex, like below. https://i.postimg.cc/4xpGMx5Q/image.png Measurement Mode could be used to measure angles m...

I put together a little puzzle, to count intersecting cubes. You can test your answers and I just added hints in the form of colours. https://www.software3d.com/PuzzleHowManyCubes.php http://localhost/StellaWebSite/Puzzle/HowManyCubesSmall.png Let me know how you go! But please don't post the answer...

Sorry there's no way to batch export. But hopefully the .OFF format contains what you need.

There's no incidence matrix as such. And you can't export 4D polytopes as 4D data. But for 3D polyhedra you can export to .OFF format, which gives a list of vertices, and then a list of vertex indices for each face. You may be able to extract what you need from that. And just curious, but what do yo...

Ulrich, your answer won't be able to create the internal parts I used, because they have other planes, planes through the centre of the compound. I'd go to a stellation view and put the model in a memory slot. Then open a dodecahedron, scale it down, and add it to the memory slot. This will put a sm...

Hi, I'm afraid you can't stop the edges being printed. Would be difficult I think to figure out which dots connected to which without the lines. I should add an option to alter the colour of shade of the lines though so you can make them lighter. For now all you can do is make sure the Line Widths -...

Very nice. Those Bruckner models are mostly painful to make!

The spheres that appear with "Display->Show Midsphere..." and "Display->Show Intersections with Spheres" are just intended as indicators, and no there's no way to alter their appearance. You might want to try "Display->Show Reflection Planes" which also looks like a sphere, but made up of great circ...

Bit confused by the common sphere thing. A circumsphere is one that passes through all the vertices, so if they shared a circumsphere, the polyhedra would not be inside each other, they would intersect with all their vertices on the same sphere. Maybe you mean a common centre, but equal edge lengths...
