I think you can do this already as follows:

Use "Poly->Keep One Part of Compound" (or Ctrl+K) to separate out one part of a compound
Put it in a memory slot ("Edit->Put in Memory" or "m1")
Do whatever editing you want
Add the result to the unedited item in memory ("Edit->Add/Blend from Memory ...

Hmm, delaying the last time would only work provided you're solving a board that no one else has, and leaves the door open for someone else to more easily beat your record. These are still world record times, taken from the table above it, but they are the boards with the longest world records, ie ...

I've renamed this new record table to "most difficult boards". "Longest world records" was confusing. Sounded like the slowest times, but it was the boards which took longest to solve, a fair indicator of the challenge they pose.

Rob.

I added a section to the world record page listing the 10 longest world records. If you're looking for the most challenging boards, these are probably them!

Thanks to TriNitro for recording this video as he played to get a new MineSweeper3D world record!

Hey all,

Just uploaded MineSweeper3D 2.6.

You can get it from http://www.software3d.com/Mines3D/download.php

I've added four new boards, as shown below.

And some nicer frames around the stats and countdown meter areas.

New world ...

The line width can be set already in the dialog box that appears before printing nets. You can increase it a bit without really losing accuracy since printers are very high resolution.

Rob.

Have you tested to see if those other colours really do come out better? I would have thought that you couldn't print a lighter colour on a darker background, but might depend on the printer.

No one's ever asked to be able to change the line colour for net print outs before. I'm afraid it's ...

My brain is obviously too ingrained with 3D!
Actually having thought some more, I think you were more right than I first thought! Here's my current thinking...

Viewing an object in any number of dimensions presumes light (or similar) travelling from the object to the viewer, and light travels ...

You can view a polygon (two dimensions) as a line (one dimension) by looking at it edge on.

But you cannot view it as a point (zero dimensions).

You can view or draw a two dimensional image of a polyhedron (three dimensions)

But you cannot view or draw it as a line (one dimension).
Actually I'm ...

Actually, that's a point I haven't mentioned before about double-tabbing, that it creates a more rigid connection, as it's like there's a third piece attaching at that edge, like an inner ribbing.

I use 120gsm paper. I found that even 160gsm was too thick. The paper seems too thin till the model ...

Nope, sorry, Stella sends nets direct to the printer. I think people have used print-to-PDF, but not sure how flexible that output is.

Can you print direct to the circuit machine?

Rob.

Hey guys,

An image of the tesseract (4D cube) made using Stella4D has just appeared in an article in the New York Review of Books. You can see it here: http://www.nybooks.com/articles/archives/2010/apr/08/he-conquered-the-conjecture/?pagination=false

It's the last image in the article.

[Edit ...

I remember making flexagons when I was a kid. Stella isn't designed to make those sort of things, although you could probably force it to print their nets if you already knew what the net needed to look like, by augmenting triangular prisms together to make a kind of 3D extrusion of the net, then ...

Nice. I should point out though that the octahedron and cube have the same symmetries, but I know what you mean
