Structural setout

The regular approach for structural setout - parallel offset of glass faces to the back – would not yield a useful structural node

Separate intersection points, >2’ apart

For this reason a different approach was used in which 1) an average vector around each node is computed from the normal vector of each face incident on that node

And 2) a bisector for each adjacent face pair is computed
