Need a good but simple 3D editor to fit in application

Thanks for the response.
I just had a look at Blender and Maya and they seem way more advanced than what I'm looking for. The visual aspect of what I'm creating is more similar to a 3D version of Visio. I'd like a pallet of objects on the side and to be able to stick those objects onto a main image.
It's only a vague representation I'm looking for not something that wouldn't look out of place in Avatar. :)

Well, I really don't think you will be able to find code that does that. What are in fact the "objects" you need to put in the image ?
It's not a kind of modeling tool you want to write ?

I don't really see the added value of the 3D here, could you maybe explain a bit more in details ?

The application has an object representation of a vehicle. The user can access and modify details about components of the vehicle through an editable representation of it. It seems to me a 3D view of the vehicle would be most suitable.

Ok, but it is much more advanced than something like Visio (in which you just drop existing shapes on the diagram).
It's really not an easy task to do something like that. I see 2 solutions:
- You use OpenGL or DirectX and write everything from scratch, but it will take you quite some effort
- You use an existing 3D engine (like Irrlicht[^]) and try to live with the limitations of the engine (for instance, I have no idea how you will be able to modify a model)

Thanks Cedric.

Hmmmm... Writing my own 3D engine. That sounds extremely time consuming. Exciting, but very time consuming. I think I'll have a look at Irrlicht.

Thanks for your help. It's much appreciated.
