I'm new on sketchup and seem to not understand this plugin. I did a toposurface and modeled all the constructions on a big area. Now im trying to drop the components (i'm guessing it's going to be a lot of work but I'm fine with that) and I can't seem to be able to drop them into the terrain... They keep floating.. want to try raytracing but i dont understand that function.
Could you help me? Thanks a lot.
