How to find intersect with Object3d in Three js?

I have a json model exported from Revit using RvtVa3c. I added the model to the scene using ObjectLoader.

var loader = new THREE.ObjectLoader(manager);
loader.load( 'mesa.js', function ( object ) {
  scene.add(object);
}

Then I tried both...

// From Va3cViewer.js
var raycaster = new THREE.Raycaster( camera.position, vector.sub( camera.position ).normalize() );
var intersects = raycaster.intersectObjects( targetList );

and...

// From three js example code 
// have onMouseMove event and raycaster initialized elsewhere in the code
raycaster.setFromCamera( mouse, camera );
var intersects = raycaster.intersectObjects( scene.children );

Both didn't find any intersect. I have read one post about calling computeFaceNormals() on geometry before trying to find intersect, but no children have geometry when I debugged the code. Is there no way to find intersect with object3d? Please help. Many thanks in advance.

Just Found this post.

Adding the second argument of "true" seemed to do the trick. 

var intersects = raycaster.intersectObjects( targetList, true );
