Re: A few pics

I have to admit a bit of ignorance. What is meant by the term “symmetry group”? Or, the mu variable? I took high school geometry in 1971, but haven’t used it much since. I didn’t get into trigonometry much, and have forgotten it anyhow by now. Is there a book I could use to bring me up to snuff in t...

Re: A few pics

Wow! Those are stunning. (Would you be able to post the files?). Since I’ve just begun making compounds, I haven’t gotten into the fine points of alignment. What I did was to bring the three polyhedrons into a memory slot for each one. My first attempt created one inside of and hiding the other. I r...

Re: A few pics

Yes, this was in the early 1970’s; I wish I could remember what the book was. I was interested, but (considering the methods of the time) I felt it would have been more work than I was willing to expend. I really want to thank you for your program ,making it so much easier. Back in the day, using a ...

Re: A few pics

Just finished my first compound, a tetrahedron, cube, and dodecahedron. Here’s a few pics: I remember seeing a compound of 14 cubes in a book, years ago. I would like to try that next. Thinking on it, I believe the 15th cube would match the positioning of the first cube (with a different face at tha...

Just completed this. I was fooling around with some of the 4D built in .stel files, and came up with this. I'll send the file next.

dividing net pieces

I'm interested in building a "Crossed Heptagrammic Cupoliac Blend, Symbol: Q+ 7/5. Some of the pieces are quite tiny! I've selected Color per face, giving 29 different colors. I've enlarged the scale to allow the maximum size which the net pieces will fit on a sheet 8"x11-1/2" (shortest edge, approx...

my vote for feature request

I definitely vote to have an option to eliminate 3d lighting. When attempting to custom color a model, it is a bit of a nuisance. For example, if I am using 3 different shades of blue, a light, medium, and a dark, when rotating the view, a light blue will change through the range of blues (by shadow...

Re: A few pics

I think I should have gone for smaller, as you say it is hard to store. I thought about giving it to a classroom, thinking that they might have more room, but my daughter wanted it for her home. You may have noticed some creases. The pentagrams (stars) are the weak areas. I reinforced some of them w...

Re: A few pics

Here's a W-76, the Rhombidoecadocecahedron approximately 23 inches tall, with each parallel plane a separate color (I think this was 23 different colors). I completed it about a month ago. It's too bad that the photos in the book "Polyhedron Models" by Wenninger aren't in color. Black and white just...

A few pics

Just a few pics of recent models I've done. W-58 done in a poinsettia styling and coloring. With, and without stamens added https://i.postimg.cc/Lhbj1MPh/IMG-0716.jpg https://i.postimg.cc/yDq9LXvH/IMG-0717-2.jpg https://i.postimg.cc/JtGkmdF8/IMG-0726.jpg https://i.postimg.cc/4nqh3QC9/IMG-0729.jpg

Re: coloring for nets

Well, I printed example nets, increasing line widths up to eight. No worries decreasing precision, it only makes the lines easier to see! Never got a "fat" line. This should work nicely!

Re: coloring for nets

Thanks for bearing with me. The print preview shows the tabs plainly. Initially, I printed on a medium green card stock paper. I couldn't see the tabs, so I printed on plain white paper. The tabs showed, but faintly, approximately the color of my card stock paper. The printer showed low ink, so I re...

Re: coloring for nets

I understand. Unfortunately, I am having another difficulty. When I print my nets, the outlines for the tabs are printing in the same color as the paper, making them invisible. I discovered this by printing one net sheet on white paper. The rest of the lines as well as the edge connection numbers ar...

Re: coloring for nets

Thanks, this is working well. I have one additional difficulty. When viewing and spinning the base view, parts of the same color appear in various tints. For example, if I were to make a piece white, it appears white only when viewed directly. It will change to various shades of gray as turned. Is t...
