I import a model, After that I assign one button & slider to that model.
When I clicked on button then Slider will be visible & based on slider moving value of scaling will be changed.
But what I want is,when I clicked on some other button then it should automatically come to its original scaling,
Why not store the original scale in an App Parameter?
When you "reset" it, just get the save value from the parameter.
Try : $scope.view.wdg['3DModel-1']['scale']=$scope.app.params.defaultScale;
