Yeah I have recieved models from art departments that were created in
Sketchup and is a total nightmare to clean. On top of what Andy said
regarding the arbitrary normal direction of polys, none of the polygons
are welded. This wouldn't be such a bad thing if the solution was just
to select your edges and perform a weld boundary edges operation,
however another interesting caveat is that you'll find is duplicates of
polygons stacked on each other. One instance I had about 10 polygons
sharing the same space. I've also had n-gon polys that had multiple
verticies stacked in the same space. And even one point and two point
polygons (at least that what it looked like). Needless to say all of
this made cleaning models for production use an absolute PITA.
my two cents,
Greg
