Dude, that is totally badass an all. But now import into blender or milkshape. Poly count turns into a rocket.
Prove it. Or no, perhaps I should just prove you wrong.
For the first model.
Edges in SketchUp before exporting: 1302
Edges in Blender after exporting to .3ds: 1804
Edges in Blender after converting triangles to Quads: 1288
For the second model.
Edges in SketchUp before exporting: 766
Edges in Blender after exporting to .3ds: 922
Edges in Blender after converting triangles to Quads: 652
The amount increase is very small and only occurs in the first place because SketchUp can create a face with any number of verticies and the .3ds format has to export geometry as triangles(In other words, more edges have to be created because each face can only be made up of 3 verticies).
And actually, its not really CREATING any more edges; SketchUp uses the same 3D geometry rules as all computers/programs and simply hides any and all coplanar edges that the user didnt specify themselves and pretends like they dont even exist while modeling, for the user's convenience. These hidden edges thusly do not show up on the model statistics window, where I get the edge counts from.
Plus, by converting triangles to quads in Blender you can reduce the polycount even further in blender than you can in sketchup.
Say goodbye to your credibility, moron.
