You add a reference to a balcony rule in the same bit that references the window generation and use a case to control its generation, like this:
attr BalconyEnabled = true Lot --> Window Balcony Window --> ... Balcony --> case BalconyEnabled == true: RuleForBalconyCreation else: NIL RuleForBalconyCreation --> ...
Thank you, for the balcony the switch works fine but fot the details such as the red top ornament it wont. it just disapeared with this rule..
attr OrnamentTopEnabled = true
case OrnamentTopEnabled == true: WindowOrnamentTop
s('1.2, 0.4, 0.3) center(x)
