The default PDF printer on Windows only does up A3 virtual paper but Bullzip does many more sizes, it works out of the box and is free. So after some configuration I now have printed tiles that I will assemble into an A1 image for manufacture. When I get it together we will see if the dimensions are ...

Thanks I will try that.

I am using a printer and driver that is capable of tiling to make posters. Using Great Stella I use the Print Setup option to configure a multi-page printing of the net on screen. When I go to Print (via preview) if the net I am trying to print is larger than a single sheet I get a message that it ...

Thanks for the quick reply.

Re printing the net for the heptagonal base; the method you give would be fine for a paper model where dihedral angles are not important as you can bend score-lines or tabs to suit when forming edges.

I want to make it out of timber so I will take the dimensions and ...

If I load the Heptagrammic Cuploid in polyhedron view I see a bowl with seven sides, each side with 5 faces, and a regular heptagon as its base.

If I display the Folding Net view the base is not rendered on the screen but the rest is. I have not hidden or unhidden any face. There is no net for the ...

Is there a general method of creating compounds from its components?

We have several examples of the form 'compound of n polyhedrons", eg compound of 2 cubes. Can you assemble it from 2 cubes? How?

Looking at ways to combine things I see that you can merge two polyhedrons by bringing one out of ...

Thank you Robert. So the problem was not with the meaning of "congruent" or "regular" but "faces". Is it standard amongst mathematicians to use "face" to include planes that may have invisible interior parts?

It looks like the nets generated by Stella are always facelets rather than faces. Is it ...

The great icosahedron is a Kepler-Poinsot polyhedron and so it is supposed to be regular. Regular means one of the most symmetrical polyhedra with all faces congruent. It has three types of triangular faces. Two types are scalene and mirror images but the third is isosceles, not the same size or ...

This work is being done in a workshop environment with various participants and I was concerned about confusion if the actual dimensions and the annotated value didn't match. I will re-scale the images on the problematic printer and print the angles but not the dimensions, and tell people to ...

I am using Greta Stella to print nets on paper to be transferred to other media. I am scaling the net to a specified edge length and printing edge and angle details on the net one facelet at a time. This is all good but for the size of one printed net. On one printer (A4) the edge length is exact to ...
