actually by the photo he provided in the meantime I'd say: just map normal steps (2D-projection of the object), don't simplify (much) but try to get the shape. Maybe both the ways have to be layer 0 at that given point, as layers only tell about relative layering order, they do not give any height-information (you could use the ele-tag for those, but don't expect current routers to recognize the distance). A structure with 2 nodes one above the other would be necessary for things like this: http://www.schmickler-metallbau.de/images/ref/WBH/Niederehe_Leiter.jpg cheers, Martin
