First time to ask questions here.
I am currently considering how to connect the parameters in "Object Attributes" with attributes that pre-defined in CGA rule files. I imitate the lines in "Building_From_OpenStreetMap.cga" which could use the parameter in "object attributes" in terms of "Levels".

PS: two shortcuts were made manually which will be time-consuming when it comes to tremendous parameters need to be connected.
attr NBayNumbers = _getNBayNumbers
attr building__Nbay__x = -1
attr estimatedNBayNumbers =defaultNBayNumbers
const defaultNBayNumbers= 8
hasNBayNumbers = building__Nbay__x != -1
case hasNBayNumbers :
