thanks stockman for the reply, but the problem are not the open paths, witch you can detect with a plugin for illustrator....
the problem is more that on vectorstock they are selling lot of traced silhouettes. the more control points a path has the higher the quality...
but I m drawing my silhouettes out of fotos and of course they dont have as many control-points as an auto traced silhouette..
so the question is whats the criteria of an inspector and how do they evaluate a silhouette shape...is there maybe a plugin for illustrator too that can do do that???
(...sorry for my bad english...i hope this time i explained my question better)
