Mesh Data and .b3d format

Hi! I'm currently trying to create a small mesh editor and have two questions about meshes and b3d files:

1. Is there any option to re-create the primitives what added in the model editor (cubes, cones, etc...)
2. Is there any option to save other data together with the model data in a b3d file?

If you're creating it in blitz,then CreateCube(), CreateSphere(), etc will create your primitives.

Any unrecognised chunk should be ignored by B3D importers, so you could create a chunk called DATA and store whatever you want in it.

Thanks. But you didn't understand what I mean with 1 (is it my bad english? :D (I'm living in Austria)). I want to read out the primitive type from Mesh data and then use CreateCube() etc.

I *think* I understand you regarding primitives.
but a B3D won't necessarily contain ANY primitives, if perchance it did, then you *could* read the primitive in as a mesh, get it's dimensions and then create the primitive.

But if you're going so far as to read the mesh anyway, you may as well construct it as a new surface, thereby removing the problem of primitives altogether.

see the b3d example for more information

Ok, I think I'll creat an special format what contains Primitive date for loading in my mesh editor, and add an export function for .b3d files.
