Enhancing the "put models on faces"-feature

What are your suggestions for enhancing that feature? Rob. This feature acts rather arbitrarily. Depending from the shape of the "target" face, the orientation of the model I want to put on it is chosen automatically. So a cube is always standing on its vertex when being put onto a triangle, a tetr...

There's a way to produce such models still more easily by using the "put models on faces"-function (a feature which could be enhanced a lot). The picture shows the core of 30 intersecting 360-fold prisms. http://i254.photobucket.com/albums/hh82/Heinzzweidrei/str_hex_360_prism_core.jpg To produce it,...

intersecting cylinders

Hi Ulrich, > This is the core of six intersecting cylinders (displayed like > 60-fold prisms). Maybe you'd consider writing a post about it and how to create it on the Stella forum? I'm sure others would be interested. Thanks, Rob. It's quickly made: Take a 60-fold prism and facet 5-fold prisms fro...

The snub colouring mode could be a small procedure of several steps. In a first step you give colours to the dodecahedral and icosahedral faces. In the second step, the faces adjacent to an icosahedral one get the same colour like this one has. In a third step, the icosahedral faces get new colours,...

Colouring Snubs

Stella has some great features to do the colour arrangements for e.g. dodecahedral or icosahedral symmetries. If you try to colour the snub triangles in a snub model in a regular way with only a few colours, (see: . http://i254.photobucket.com/albums/hh82/Heinzzweidrei/SnubDodeca_ColourArrangement.j...

are you able to make your figures rotate in the stella program, with the top tetragon rotating in the opposite direction from the bottom tetragon both in the same display? No, I can't do so. I have to make some detours like I described before to get this visible. But Someday I'll get around to addi...

for a merkaba (sacred tetrahedron), or the one i like even better, the octahedron, to function as it is supposed to -- then the top half of the figure must be set to spinning or turning on the vertical axis, and the bottom half must be set to spinning on the same vertical axis but in the opposite r...

Ulrich, would you please tell me how? i really want to know this. It is a series of 20 images which I exported from stella. As Robert says, I created 20 different models, starting from a 60-fold prism. By faceting, I got 20 3-fold prisms from it which I trimmed to the proper height which is the dis...

Yes, I created the images with stella.
can you make it rotate, the top spinning opposite to the bottom?
This should be possible too, but it's not that easy with stella if you don't use parallel planes.

Perhaps you should spin it like that:

Alex,

do you still remember how you did it and could you explain it?

I did it by augmenting an 8-fold antiprism by icosahedra. Then I faceted new icosahedra, taking care that two neighboured ones use the same set of vertices of the triangle they are both connected to. http://i254.photobucket.com/albums/hh82/Heinzzweidrei/ring_icosa_8_fac.jpg This results in icosahedr...

Squeaky, I had a look at the augmentation section of the manual and I found that the results of the procedure above can be obtained much more easily by the Ctrl+Left-drag (interactively change the height of the augmentation when using a pyramid, cupola, prism, or antiprism) and the Ctrl+Right-drag (...
