I have been messing around with this issue as well, in the threex.dilateGeometry.js, I added this to make it work

    geometry.vertices.forEach(function(vertex, idx){

            /* added this if statement to make it work*/
        if(typeof(vertexNormals[idx])!=='undefined') {


            var vertexNormal = vertexNormals[idx];
            vertex.x += vertexNormal.x * length;
            vertex.y += vertexNormal.y * length;
            vertex.z += vertexNormal.z * length;

        }
    });     
};`

I had the same problem, I solved it doing the following

geometry.vertices.forEach(function(vertex, idx){
		var vertexNormal = vertexNormals[idx];
		if (vertexNormal != null){
			vertex.x	+= vertexNormal.x * length;
			vertex.y	+= vertexNormal.y * length;
			vertex.z	+= vertexNormal.z * length;
		}
	});
