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.
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 ?

ThreeJS 3D: (see the triangles and diagonales)
it looks like you are drawing all points/polygons as single polyline
extracting perimeter line
Bad triangulation
