Light Weight Roof - Documentation for Tender Stage - Part 3/3

documenting the pieces for the tender stage:

each rib is projected on the xy-plane and labeled, due to a prevciuosly ellaborated labelling system

the most tricky part: since up to 8 ridges meet in one node it was crucial to label the nodes uniquely

missing:
documentation of the triangular panels
documentation of the border pieces
and some other stuff

hope to complete it soon
