Attributes rule

LukeCzar

Hi Matthias,


Quick question, we use the gdb file with attributes already inside each room,  for instance, one floor has lower walls the other upper - in attributes, so we would like to create a new rule that would extrude lower walls 2feet and upper 4 feet, how do we use python to make the program read from the attributes that are already in gdb ?

Hi

Do you know the heights of the building, or the number of floors of the building?

If it's heights you'd want something like

 attr height = 0  #this looks at the height attribute in your building parcel (note the same should be exactly the same as that in the object attributes
attr floor_height = 3.8 #value here should be the height each floor is

Lot-->extrude(height) Building

Building-->comp(f){side : Facade | top : Roof}
Facade-->split(y){{floor_height : Floor }*| ~1 : Wall} # what this does is split the building up so that based on the building height it creates the floors 

If you have the number of floors it's similar to the heights but:

attr number_floor = 0 #again same name as what's in your object attribute
attr floor_height = 3.8 #use what ever average floor height you want here
attr building_height = number_floor*floor_height #this determines the building height based on the other factors

Lot--> extrude(building_height)
etc.

hope that helps 🙂
