Is it possible to get the poly and vertex cout for a Mesh or ObjectContainer3D?  I didn’t see it in the documentation, but figured I must just be missing something.

Thanks!

var mesh:Mes; // your mesh!
// extract vertices data
var rawVerts:Vector.<Number> = mesh.geometry.subGeometries[0].vertexData;
   var verts:Vector.<Vector3D> = new Vector.<Vector3D>();
   var v:Vector3D;
   for (var i:int = 0; i < rawVerts.length; i+=3) {
    v = new Vector3D(rawVerts[i], rawVerts[i + 1], rawVerts[i + 2]);
    verts.push(v);
   }
   // extract faces data
   var rawFaces:Vector.<uint> = mesh.geometry.subGeometries[0].indexData;
   var faces:Vector.<Vector3D> = new Vector.<Vector3D>(); // x, y, z are vertices: 1, 2, 3
   for (i = 0; i < rawFaces.length; i+=3) {
    v = new Vector3D(rawFaces[i], rawFaces[i + 1], rawFaces[i + 2]);
    faces.push(v);
   } 

Lengths of “verts” and “faces” are total number of vertices and faces respectively.

Cool!  Thanks for the quick response!
