Hello,
i have noticed that the get_info function returns a null value. i believe that there is a problem with one of the libraries.
this is the code i've used to try and acess the volume and other info using the get_model_info() method.

<title>Viewstl Javascript Plugin - Simple Example</title> 
<body>
    <div id="stl_cont" style="width:500px;height:500px;margin:0 auto;"></div>

    <script src="stl_viewer.min.js"></script> 
    <script src="parser.min.js"></script>
    <script src="three.min.js"></script>
    <script src="CanvasRenderer.js"></script>
    <script src="OrbitControls.js"></script>
    <script src="Projector.js"></script> 
    <script src="webgl_detector.js"></script>
    <script src="TrackballControls.js"></script>

    <script>
        var stl_viewer=new StlViewer
        (
            document.getElementById("stl_cont"),
        );
        stl_viewer.add_model({id:0, filename:"mystl.stl"});
        
        alert( JSON.stringify(stl_viewer.get_model_info(0)) );
        
    </script>

</body>

Hi, sorry for the late response, you have to wait the model to load before calc its volume,
please use "ready_callback" option, like this:

var stl_viewer=new StlViewer
        (
            document.getElementById("stl_cont"),
            all_loaded_callback:loaded_callback
        );
stl_viewer.add_model({id:0, filename:"mystl.stl"});

function loaded_callback()
{
       alert( JSON.stringify(stl_viewer.get_model_info(0)) );
}

BTW. you don't need to load all of the libs above, only stl_viewer.min.js

Hello thank you so much! I figured it out after a day so its okej :)

I tried to access the volume setting through another domain called Bubble.io. i uploaded a file on that domain and tried to calculate its volume but when i run the code, i get an error saying that the web worker couldnt be constructed. Do you maybe know how to fix this issue?

It can't load some js files for some reason, try to load them manually:
three.min.js
stl_viewer.min.js
parser.min.js
load_stl.min.js
webgl_detector.js
CanvasRenderer.js
OrbitControls.js
TrackballControls.js
Projector.js

and set "load_three_files:false" at the init options
