Hi Giuseppe. I was able to get the model coordinates to show on a label within the experience doing the following:
- Set up App parameters xpos, ypos, zpos

2. Create 3 2D or 3D labels within your experience to display the coordinate values
3. Create a button with title 'show coordinates'
4. Bind xpos, ypos, & zpos to each corresponding label 'text' property.
5. Add code to Home.js
$scope.showCoords = function(){
var Xpos = document.querySelector('#model-1').getAttribute("x");
$scope.app.params.xpos = Xpos;
var Ypos = document.querySelector('#model-1').getAttribute("y");
$scope.app.params.ypos = Ypos;
var Zpos = document.querySelector('#model-1').getAttribute("z");
$scope.app.params.zpos = Zpos;
};
6. Call showCoords(); on button click

7. Save & publish.
Here is what my preview looks like
