Unity 3D Tracking Object Placement

Hi guys, I have been testing with the Unity 3d tracking features and I am quite confused about how Wikitude is defining the 3D cordinates to place the the AR Object (for example the Eye into the default wikitued demo scene). What I want to know is if there is a way to know into the editor, how the objecti will going to be placed (position and rotation) when launching the 3D tracking app. Right now I am testing with the 3d tracking default scene and each time I rotate the AR Object ( I have replaced the default eye by another mesh), it didnt rotate as expected into the App, so I want to know how can I predict the way it will going to be placed or if I am doing something wrong or if there is a workflow to achieve that.

Another doubt I have is because I dont have anything inside the scene to use as reference when using 3d tracking, how should I know if the object will going to looks smaller or bigger? is there a way to know that too? or it is a matter of trial and error?

 

Thanks,

 

Juan.
