This is an example of Dynamo routine to automate the the Room code defined by a client. The graph must run over each view. Finally all the Room data is exported to an Excel spreadsheet. The code characters mean the following:

​

A-201​

A = Code Building Block

2 = Level

01 = Number of Room

​

Each room in entire project has its own code. The routine was helpful filling the tag rooms and developing the scheduled areas. Also it has a custom Python nodes, on left below the node replace some room names to its readable string and the other find a building code from the view name.
