Building Noise Map

The facade points of the building noise map can be accessed via the following syntax:

for o in cna.tables.building:all() do
    for f in o.fac_points:all() do
        cna.print(f.LP1)
    end
end

Note: The identifier for buildings (building) and not for building evaluations (bld_eval or building_evaluation) must be used, see first line.

The iterator returns the facade points floor by floor. For each floor, it iterates over all associated facade points. The first facade point is the one generated near the first polygon point in polygon order. To show the enumeration, you can select Number at Print in Symbols.

Available attributes can be seen in the Object-Scan, after selecting Object Type: Facade Point and clicking on . This list includes attributes of the building evaluation (for example ID, BEZ or ART) and facade point (for example TOT_EINW, FAC_EINW or STW).

The attributes DIR, HIRI and HIRI2 must be accessed with the prefix MEMO_. For example, the access to attribute DIR is f.MEMO_DIR (instead of f.DIR). Using MEMO_FLOOR returns the string representation of the floor as defined at Miscellaneous, for example "EG" instead of 0.
