Hey Brian, give it a metallic material, make it glow hott white and enter it into the 50's SciFi contest! LOL

Great alien saucer if I say so myself :-P

Hi Brian,

Here's a 3DM file of a Diamond from one of the Rhino jewellery Plugin's I've got.
I'm also including a picture that contains the angles & proportions that are used for cutting an "Ideal Diamond".

Here's a link that might also prove useful.

Hope all of this is of help, Colin

Thanks Will and Colin.

Just where could rendering alternatives end up?

here is a another cool source with 3d models of real gemstones including .3DM, as well as jewelry related information

Those 3DM Rhino files (3dlapidary) do not open in MoI?
(OK in Carrara)

Any explanations?

Hi Brian,

> Those 3DM Rhino files (3dlapidary) do not open in MoI?


That usually means that the objects inside of the 3DM file were polygon mesh objects and not NURBS objects.

There are various different kinds of things that can be stored in a 3DM file such as NURBS objects, polygon meshes, spotlights, dimensions, etc....

MoI only deals with NURBS and single point objects, it will skip any polygon mesh objects that are in the file and I think those particular files only have those kinds of objects in them.

Those polygon mesh objects can be converted in Rhino into NURBS objects by using the meshtonurb command on them. That conversion will allow MoI to read in those objects.

oops sorry for the incontinence caused, I should know that...

Well one needs something to grumble about I guess!

If you want to do accurate jewel stone modeling you need a cut sheet. It will give you the proper angle/dimensions for a particular cut of precious stone.

See this post for pics and an example file.
