title: Import 3D model in SceneKit - Swift
body: <p>I'm creating a game where the player can control a cube.</p>
  
  <p>He could buy new cubes.</p>
  
  <p>I created the basic cube like that :</p>
  
  <pre><code>// MAIN CUBE
  
  mainCubeGeometry = SCNBox(width: 0.2, height: 0.2, length: 0.2, chamferRadius: 0.0)
  mainCubeGeometry.firstMaterial?.diffuse.contents = UIColor.redColor()
  mainCubeNode = SCNNode(geometry: mainCubeGeometry)
  mainCubeNode.position = SCNVector3(x: 0.0, y: 0.0, z: 0.0)
  scene.rootNode.addChildNode(mainCubeNode)
  </code></pre>
  
  <p>I would like to know how use 3D models (dae) of cubes created on any software (SketchUp per exemple). I don't really understand how to load the 3D file when the scene is created (<code>scene = SCNScene(named: "3d.scnassets/cube.dae")</code>) because it is a scene, so it import a scene into my original scene, while I just want to import a 3D model in a node to use it like my basic cube.</p>
  
  <p>Thanks for your help !</p>
