Thomas Sebastian, you do not need to dissolve the polygons if you are only interested in placing the random points within the layer bounds as Andrea says. If you have a non-rectangular dataset then your layer bounds could result in points being placed outside the polygons in your dataset; you should do the dissolve and place the points within the dissolved polygon. If like me you live in a rectangular / map-sheet-ish world then by all means work in the layer bounds. -- Chris Hermansen · clhermansen "at" gmail "dot" com C'est ma façon de parler.
