I'm not really aware of any special name for that method... I would call it a kind of "geometric" solution since it is setting up additional geometry to intersect to find the right point.

For more information you might try googling "platonic solids". You'll probably find some other methods that calculate what the various angles have to be for the pieces to meet exactly.

Those polyhedron files do not Thumbnail--as do not MoI 3DM files!

Hi Brian,

They were possibly saved from Rhino using the "Save small" function which tries to reduce the amount of stuff stored in the file.

If you want to get Thumbnails, save them from Rhino without using Save small and that should make a thumbnail image inside the file.

I only have the demo of Rhino.
The thought of having to take MoI files, via Rhino, to save them out with the thumbnail???

Something for the MoI wish list?

Brian

Hi Brian, yup it is already on the wish list.

That's just a method you can use if getting the thumbnail is an important thing for you to have right now.

Hi Brian,

I use Firefox as my web browser, with that I'm able to save the web page with all it's images.
So here's a ZIP file with all the relevant images for you, just keep them in the same folder with the 3DM files.

Hope it's of use to you.
regards Colin

Thanks Colin
I am lucky to have very top Adobe Suite stuff (Acrobat8 Pro) so I do (and did) save web pages like that as a pdf file.

PS It's my sons spare computer that I use. Full CS3 Extended Suite.
And, I have never had problems, in all these past years ,with Windows IE! I love it!

Dunno if this solution has been proposed yet

That looks pretty close to PaQ's method here, another good one lwan, thanks for posting it.

oops yes indeed, looks pretty close :)
