How to display the mesh render of an object target in Vuforia when using Unity?

I’m trying to use the new object recognition feature in Vuforia, the problem is after I scan an object and import it to unity, I can’t display the 3D-model of the object. So I have to blindly calibrate the model I want to Augment on the scanned object. Is there anyway I can display the mesh renderer of the 3D-scanned object to make it easier?
