Bonjour,
je voudrais vous présenter la façon dont je construis mes polyèdres. J'espère pouvoir participer régulièrement aux discussions dès que j'aurai fait l'acquisition de Stella

Bonjour,
pour l'instant, je n'ai pas encore acheté Stella, j'ai eu les calculs sur le site de David I. McCooey
http://homepage.mac.com/dmccooey/polyhedra/DualSnubHexpropelloDodecahedron.html
Je ne suis pas spécialiste mathématique des polyèdres, mais avec les calculs, je peux les réaliser en bois. J'ai vu sur la version d'essai de stella, qu'il y avait de belles possibilités pour construire de très beaux polyèdres. J'ai hâte d'avoir ce logiciel.
Vous pouvez reprendre les croquis sur le fichier PDF, pour un diamètre de 600 mm.
Bonne soirée
Roland

Hello,
for now, I have not yet bought Stella, I had the calculations on the site of David I. McCooey
[url] http://homepage.mac.com/dmccooey/polyhedra/DualSnubHexpropelloDodecahedron.html [/ url]
I'm not an expert mathematical polyhedra, but with the calculations, I can make out of wood. I saw on the trial version of stella, that there were great opportunities to build a beautiful polyhedra. I am looking forward to this software.
You can resume the sketch on the PDF file, with a diameter of 600 mm.
good evening
Roland

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-and-down in the top right corner of that view to make this the new base model, and then you can create nets and stellations etc.

Bonjour,
OK Robert, c'est beau.

Quelques précisions concernant l'assemblage des faces du polyèdre. Il ne faut pas coller les faces au fur et à mesure car les petites erreurs s'accumulent très vite et il devient alors impossible de continuer. La solution comme sur la photo de l'url du 1er message, est de tout assembler avec du ruban de scotch et ensuite de coller par capillarité avec de la colle glu.
A savoir, mes bois ne sont pas découpés à la commande numérique, mais ajustés avec une ponceuse à disque de 600 mm où je peux incliner la table à l'angle souhaité.
Cordialement
Roland

Hello,
OK Robert, it's beautiful.

Some details of assembling the faces of the polyhedron. Do not stick to the sides as and because small errors accumulate very quickly and it becomes impossible to continue. The solution as in the photo of the url of the first message, is to assemble everything with scotch tape and then stick capillary with glue glue.
Namely, my woods are cut with CNC, but fitted with a disc sander to 600 mm where I can tilt the table to the desired angle.
cordially
Roland

I don't use CNC either Wink

Si je colle les faces au fur et à mesure du montage, les petites erreurs s'accumulent très vite, et les décalages deviennent importants d'où l'importance de faire tout le montage du polyèdre avec du scotch. J'ai oublié de dire que je termine le serrage avec des colliers crantés en plastique (collier Colson)

Tous les angles au sommet et les angles dièdres sont réalisés sur cette ponceuse (au fond de l'atelier) en inclinant la table et avec des gabarits.
Bonne soirée
Roland


If I stick to the sides as and assembly, small errors accumulate very quickly, and the shifts become important so it is important to do all the editing of the polyhedron with tape. I forgot to say that I finish tightening with plastic notched collars (collar Colson)

All apex angles and dihedral angles are made ​​on this sander (at the bottom of the workshop) and by tilting the table with templates.
good evening
Roland
