A selected building can be given a user name.
Simply select the naming function from the context menu and enter a name.
Please use letters, numbers and only.
Names of AREAL-buildings must be unique. Therefore, if more buildings have the same name, the tool will add a suffix, if needed (so do not worry, if new buildings have same names first...)
This normally happens automatically in the background,
but definitely, when the user starts the calculation.
Building names can also be changed in the standard sketchup entity options, but at the moment sometimes the name entered gets lost (especially, when you enter a name and select a non-sketchup-tool after this). We are looking for a better solution.
You can delete all buildings' names from the AREAL3D pulldown menu. This function will delete all automaticly assigned names and name all those buildings again.
Building names are also important for floorfiles, where heights of buildings can be saved (sort of 'snapshot').
