The graph is quite big for an image so I have attached the DYN file. At the moment it is working on all gridlines but once we get the agreed list on an excel spreadsheet it will use that to determine the sections to be created.
As to the Building coder link I don’t realy have any experience with python or coding so it is a little beyond my skills at the moment
Thanks
Darren
