I want to open an attached pdf when i click on a part of 3d model.

when i try host.exportDataObject({ cName: "MindSphere_GettingStarted.pdf", nLaunch: 2 }); it throws an error

this is my complete code:

//start

var myMouseHandler = function( event ) {

if ( event.isMouseUp ) {

var myMesh = null;

if ( event.hits.length > 0 ) {

myMesh = event.hits[0].target;

}

if ( myMesh != null ) {

host.exportDataObject({ cName: "MindSphere_GettingStarted.pdf", nLaunch: 2 });

}

}

}

var mouseEventHandler = new MouseEventHandler();

mouseEventHandler.onMouseDown = false;

mouseEventHandler.onMouseMove = false;

mouseEventHandler.onMouseUp = true;

mouseEventHandler.onEvent = myMouseHandler;

runtime.addEventHandler( mouseEventHandler );
