Controlling Model Item Opacity Using Toggle Button

you can use this script to change the opacity of your model.

$scope.opp=function(val) {
switch(val) {
case 1:
$scope.view.wdg['model-1'].opacity= 0;
break;
case 2:
$scope.view.wdg['model-1'].opacity= 1;
break;
}

};

you can call

opp(1); into key pressend of toggle button     

and

opp(0); into key unpressed of toggle button.

bye
