Sketchup model > Collada > THREE js = no edges

Question

I exported a very simple Sketchup model into a Collada dae file. When imported back into Sketchup edges are the original black; imported into THREE editor edges are white; in simple THREE project edges don't appear at all but everything else seems OK. Any ideas about this?

I found your problem just yesterday because i had the same problem and was searching the web for a solution. Nothing... but i solved it.

First of all make sure that when you export Collada from Sketchup, in options button Export Edges is checked.

If the edges are white and you want them to be black or any color you must edit one line in three.js

search for

    function LineBasicMaterial( parameters ) {

    Material.call( this );

    this.type = 'LineBasicMaterial';

    this.color = new Color( 0xffffff );

    this.linewidth = 1;
    this.linecap = 'round';
    this.linejoin = 'round';

    this.lights = false;

    this.setValues( parameters );

}

and change this line

this.color = new Color( 0xffffff );

to this

this.color = new Color( 0x000000 );

I hope this solves your problem
