Is this what you want?

You can see this by using "Display->Show Vertex Angles" and then selecting a vertex with Ctrl+Right-click. The yellow angles are what you want, if I've followed what you're asking. These are the ...

Hi Dwight,

If anyone has videos involving Stella, this forum would be the perfect place for them. I've only made one video so far, but it was quite an advanced one. You can find it here:

To obtain nets, you must first convert the model in this morphing view to become the new base model. Use the left-and-down arrow button in the title bar of that view.

The model in your avatar is rather easy to create in Stella.

Start with a truncated icosidodecahedron, then change one of the views to the "Morph Duals by Augmentation" view-type. Go to 50% through the morph (which is the default, or hit Ctrl+Right-click otherwise), and there it is!

Use the left ...

There are lots of ways to get there, but it is not a built-in model as such. First you'll need to make sure you've got a stellation view open. Select one of the views (by clicking in it) and use "View->View Models->Base Stellation" (or the much simpler toolbar button).

Use "Stellation->Stellation ...

Re: Some suggestions (obj import, 64bit, display all stellat

Well, it's taken me almost a year, but here's a reply at last! Sorry, it went into the too-difficult-to-reply-to-quickly category, and then got left behind indefinitely. This reply may still be sketchy, but I'll see how I go.

Two reasons.

(1) Any model created (either internally or via import) is aligned to a template symmetry group.

(2) When exporting, the model is exported as seen on screen. So if you rotate the model on the screen, then it will be exported in a different orientation. I suggest using something from ...

Re: 2 Newbie questions

Hi Paul,

I'm not at home right now so I can't check, but I think the mitre angle is (180 - dihedral angle) / 2. It's the angle you need to set on a tool for mitring wood. Some people have said it should be different, but there seem to be different opinions about it, so I'm not sure.

To deselect ...

Stella on TV

Back in 2003 there was a story about Great Stella on TV.
You can see a bunch of my paper polyhedra here too.

I think I can answer your question.

Models are exported with the same orientation they have on the screen at the time of export. So if you rotate it to a weird angle, then it is exported at a weird angle. However this is intended as a feature...

Stella shows number of vertices in the Info window.

Otherwise, you could note that each vertex touches exactly one pentagon. There are 12 pentagons, and so 5 x 12 = 60 vertices.
