Hey! I also think this is a very important one but I'd explain it in a slightly different way.
I think we need a new "structural profile tool" something that can avoid the geometric limitations of beam/column and that can access saved complex profiles. Just a 3d polyline (if could be nurbs would be amazing) that is the rail for a swept profile.
In the new architecture sometimes columns become beams and vice-versa. This problem is specially relevant when working with the Grasshopper Connection.
