Wow thanks a lot Olivier - that looks like it will do the trick. The reason I didn't want to use curves is merely that I will get a lot of polygon islands and don't know how to automagically select all border edges for extraction - otherwise curve tangency would be fine. The Get Gg node just before Align Particle to Vector looks like it is the one that provides the edge vector, correct!? But I fail to understand what it is doing though.
