I am pretty new at this so please be patient. It looks to me like I am to blame but I need to get past it. I do the pressure plate tutorial. Near the end we duplicate and rotate the one boss. That is great. My project involves the 4x4 steel tubing. In effect I have a set of legs at the end of a bench. I want to have 4 sets of legs (linear pattern) when I am done.... linked to the first sketch of course.... I can't get the "Features to Pattern" window to accept any part of the tree, not sketches, not individual structural members , and not groups of members like the leg assembly. End conditions would ultimateley be different between the outer and inner legs but I cant get to that foreseeable problem. Now what?
