Hmm, not sure. If you had the cross-section view selected, or the cell view, then you'd be looking at a 3D model, but not quite the ones you describe. In 4D views cells are reduced in size by default so that you can see the internal structure better, but if you scaled them up to full size it would j...

I'm not going to attempt the maths, but some of those look similar to stellations of the pentagonal icositetrahedron. See here:

These are all easily made in Stella.

By toggle the check box you mean on the menu? "View->Toolbars->Show View-Type Toolbar"? If that's ticked, then maybe somehow it got moved off-screen. I haven't heard of that before. Try turning it on and off (via the menu) and watch carefully for anything appearing disappearing anywhere, possibly ju...

The non-convex Archimedean polyhedron sharing the edges, vertices and triangular faces of the cuboctahedron - but having the diametral hexagons in place of the square faces. I suspect that all the vertices in the compound of five such, dodecahedral symmetry, can be folded without cutting - with som...

Yes, that compound you mention is interesting. It has two different types of starry vertices, and both can be folded from flat paper without a cut to the vertex. I keep meaning to make one. Here's the .stel file if any Stella users want to have a look: http://www.software3d.com/StelFiles/GreatDod+St...

Stella can't export to PDF, although you might be able to find a virtual printer which lets you print to a PDF file instead of a printer. Better though to just export images using "File->Export Image" and work with the other image formats. When exporting you may choose high resolutions, as well as o...

Hi, I wish I had a 3D printer! You can probably find a way to convert from .OBJ format to .STL, but I'm afraid I don't know how off-hand. One tip: always export your model from the stellation view. In this view, only the externally visible parts of faces are exported, ie only the outer shell. Your 3...

Sounds like you don't want thick bevelled faces, but thick unbevelled faces would suffice (ie shallow prisms). This is probably even easier that Ulrich's idea. Start with your model, put it in a memory slot (eg hit "m1"). Select the face you're interested in and hit "a" to augment it. Select "prism"...

I'm not sure what math your after. Different shapes are made different ways. Many categories, like uniform polyhedra, stellations, etc took me a long time to get working, and were not really just implemented based on any standard formulas or algorithms. It sounds like you want to create these polyhe...
