Remove or isolate part with JavaScript?

Question

Hi folks,
as you know you can remove or isolate parts in the modelhierarchy with a few clicks. Now I want to do exacactly the same with JavaScript to add this function to a button or something similar.
So I can have a button like "show part xy" and only this part is shown in the 3D view and other parts are not visible.
Is there any chance to do this?
I think there's a workaround with creating an animation like an exploded view where certain parts are removed. But a simple funtion would be much more easier I think.
thx in advance,
Tobias

Hi,
I didn't check whether the following code actually compiles and works, but maybe it does what you're trying to accomplish...
[3D annotation JavaScript code, associated with the container for Your embedded U3D model]
function makeAllMeshesInvisible ( )
var howManyMeshesInScene = scene.meshes.count;
for ( m=0; m < howManyMeshesInScene; m++ )
var myMesh = scene.meshes.getByIndex(m);
console.println("Making mesh " + myMesh.name + " invisible.");
myMesh.visible = false;
function makeMeshVisible ( meshName )
var myMesh = scene.meshes.getByName(meshName);
if ( myMesh )
myMesh.visible = true;
else
console.println("There is no mesh named " + meshName);
[Document JavaScript code, e.g. associated with a button]
// getAnnots3D(pageNum)[annotIdx]
context3D = getAnnots3D(0)[0].context3D;
context3D.makeAllMeshesInvisible();
context3D.makeMeshVisible("nodeName");
Please note that the 3D viewer must be active for the button to work properly...
I hope it works and helps!
