Adding URL to a 3D object

Question

Hello,
I have 3d model from Microstation saved in format u3d. I create 3D pdf from this model. Now my problem is:
- I need insert URL to this model
(This should go with JavaScript, but I don't now how)
Second question is:
- is possible default disable some layers of the model?
(All the layers are by default activated)
Thanks

Hello,
thank you for your answer, but is not much helpful for me..
"- I need insert URL to this model

I know the HyperlinkExample.pdf, but is it only example,..I don't know how.
If I uncompress this PDF , I saw javascript like this: (parts of javascript)
function PDF3DSDK_LaunchURLWrapper(url)
    try{
        app.launchURL(url);
    }catch(ex)
        console.println("HostScript: error during launchURL; url = " + url);
endstream
endobj
//& this
var pdf3dsdk_linkTypes     = new Array( PDF3DSDK_MESH_LINK_COUNT );
// possible values are:
// launchURL - opens a URL at new (external) browser window
var pdf3dsdk_linkParams1   = new Array( PDF3DSDK_MESH_LINK_COUNT );
pdf3dsdk_linkMeshNames[0]  = "PDF3DLabel_launch_url";
pdf3dsdk_linkCompareType[0] = "like";
pdf3dsdk_verboseModes[0] = 0;
pdf3dsdk_linkTypes[0]  = "launchURL";
pdf3dsdk_linkParams1[0] = "http://www.pdf3d.co.uk";
function pdf3dsdk_DoLaunchURLActionForIndex(index,node)
    try
        host.PDF3DSDK_LaunchURLWrapper(pdf3dsdk_linkParams1[index]);
    }catch(ex)
        console.println("3DScript: error during launchURL; url = " + pdf3dsdk_linkParams1[index]);
I think that these functions should provide operations Adding URLs into a 3D object,
isn´t it ?  Thank you
"- is possible default disable some layers of the model?
I do not know what the layers are. Some Microstation term?
But nodes in 3D PDF model can be switched on and off -
interactively, via annotation properties (node dictionaries) or JavaScript." -
Yes, layers are "nodes" in Acrobat. I know how switch on and off this nodes interactively, but I need some nodes deafult switch off. When I open my model, every nodes are switch on...
JavaScript is maybe solution, but I don't know how to do it.
