well to be honest, no offence to you Oskar, but why would shapeways need a filter for that?
how could the upload system see if that's correct or incorrect?
if you mean by: there are more objects overlapping each other,, i would say this:
Most of the things i upload are models that are build from over 20objects (like the shapewaysbike i created, it has about 50objects that will form the bike)
So that means i will get al sorts of errors from shapeways cause of overlapping objects
I think it's just somehting you have to look out for yourself!
if i'm totally wrong,, then your totally right
and again Oskar, niets persoonlijks hoor (nothing personall)
