title: How to remove wireframe diagonals?
body: <p>I wrote a custom exporter for CAD software to export geometry data to ThreeJS editor. Now, of course in ThreeJS I wrote a correct loader which is loading all the geometry correctly.</p>
  
  <p>There is just one problem; In wireframe view in ThreeJS I have triangles from each vertex. With what technique can I remove the triangulation and diagonals ? How can I show wireframe without diagonals ?</p>
