You're right, I can replicate it. Happens when only excavating a single octahedron. By the way, if you turn off tabs it works, so it's an issue when creating tabs. Weird because this has been tested against so many cases. I'll try to figure out what's happening.

Unfortunately it won't be any time soon, as I have some work to get Stella back to a releasable state, and have been working on other things too. But next major release will definitely have ability to export nets to SVG.

I already have this working. I have a Cricut Explore Air, which can hold two ...

It reports printing larger than the page as an error so that the user knows to split the net up into smaller pieces or use larger paper. You can't disable that I'm afraid.

Can you tell it you're printing to larger paper somehow. Maybe use a virtual printer that sends output to PDF and tell it to ...

Change this setting. Because the edges coincide with another edge behind them, it is splitting the nets so that there will be tabs behind to attach internally for extra support.

I'll take this as a feature request.

But why always ask why? The answer is usually the same: because it hasn't been implemented.

There will always be things implemented in 3D that aren't also implemented in 4D (stellation, faceting etc). I could remove all those things from 3D to make it ...

Squares are flat. Do you mean the compound of 5 cubes?

I think you are asking about the extra white parts I used to add strength inside, and help to get the last part in, as seen in image below, with description "For added strength, and keeping in mind how I ...

Well done Ulrich, if you found a work-around. Here's a screenshot showing the steps, after right-clicking on desktop and selecting "NVIDIA Control Panel".

Very first thing to do would just be the Platonic solids and Archimedean solids.

After that, try the Kepler-Poinsot polyhedra (small stellated dodecahedron, great stellated dodecahedron, great dodecahedron and great icosahedron, probably in that order).

Then you could move onto some of the uniform ...

Correct, I wouldn't expect that to work.

Stella would print all the parts out, including the red triangles, but it can't tell you what order to put things together. You can use "Nets->Show Edge Data->Edge Connection IDs" to print IDs on tabs that you can match up though.

Or just look for the triangles with matching edge lengths to connect ...

I believe I've fixed this, but not in a released version yet (and that will be a while). It only happened on some machines, especially laptops with certain graphics cards.

In the meantime, you could try looking in your GPU settings for a way to adjust the level of hardware acceleration. Turning it ...

Symmetry groups in 4D are way more complicated than in 3D. I'm afraid I don't have any plans to add them at the moment. I've thought about it, and maybe some day, but won't be any time soon. Selecting subsymmetries would also be less useful at the moment in 4D than it is in 3D, as you can't create ...

Stella uses OpenGL, so any card that supports OpenGL will provide hardware acceleration. nVidia cards are generally very good for that. So yes, your GPU should make Stella render faster.

Because it doesn't happen automatically. There are different representations internally when drawing different things, and they don't all support things like this. The preview is not as important as the final.

Did you click on it for the larger image? May still not be clear, but there's a small red triangle on each side connecting the orange parts together.
