I've recently written a .3ds decoder in Java. I want to avoid exporting to .3ds every time I update a model. Has the file structure been released for .SKP files?

What about the file structure for a sketch up file, has that been documented yet? Right now I'm working on a 3D engine in Java. I'm using 3DS because it's really basic to decode. I would love to skip over all this exporting and simply load a sketchup file.

While you're here, is there a simple way to place an object's center around the origin?

Wow, I looked everywhere for that options button.

I read that but I still couldn't find the options button. Thanks for the speedy response.

I'm sure this question has been asked a million times before but every time I search .3DS or any variant, nothing comes up.

Is it possible to export a 3DS file with the vertices in tack? Only the faces are being exported.
I have Google Sketchup 8 pro.
