X,Y,Z coordinates of an object in the viewer when you select it from the tree

Question

is it possible to get the X,Y,Z coordinates of an object when you select it from the object tree itself. I know you can do it when you mouse click on a particular object but i want to get the coordinates when using the navigation tree. Is there a way to get them using the viewer ?

Answer 1

If the model browser's selection behavior is set to default (isolation) then simply subscribe to Autodesk.Viewing.ISOLATE_EVENT as you would for selection:

NOP_VIEWER.addEventListener(Autodesk.Viewing.ISOLATE_EVENT, e=>{
//NOP_VIEWER.utilities.getBoundingBox().center()
})

BTW you can customize interaction behavior for the model browser by specifying the click config here:

NOP_VIEWER.modelstructure.clickConfig = {
  click:{ 
    onObject: ["toggleMultipleOverlayedSelection"]
  }
//...
}
