You can work with their free version, but will have to pay for mobile licenses to deploy your app to devices - http://unity3d.com/promo/unity4/

Unity offers a 30 trial that includes their Pro and mobile licenses as well.

If I use the Unity SDK for solve this problem, the Unity is free for not?

Sorry I don't have any samples on how to do this, as this is a significant piece of work.

This is why we have the Unity SDK which is definitely worth a try because it makes this a much easier task.

Thank you Nalin S. But I don't know how to do that. Do you have any example or something else that I can adapt in existing sample.

Hi gun0051

From what you are saying it sounds like you need a 3D engine to be integrated with Vuforia that can provide this type of functionality.

Although I have not tried it this engine claims to do this in one of its samples:  http://nineveh.gl

The other option you might consider is to build a module that integrates with the existing samples and which can handle loading through a set number of formats e.g. Collada / Pod.  You might be able to make some quick progress if you can find samples that display such files in OpenGL ES 2.
