Adjust attribute dimensions based on split part

[jabrett]

Hi, 

I'm trying to create a T-shape (to ultimately put into a recursive extrude floor function). I'm trying to make the setback adjust according to the respective split part. Does anyone have any suggestions? Apologies I don't have a lot of cga coding experience. Thanks!

//Initial shape with attributes for width or setback

attr frontSetback = 3

attr rearSetback = 3

attr sideSetback1 = 3

attr sideSetback2 = 6

attr LotArea = 0 # used to calc FSR

attr width = 0

case name == "Front" : setDimensions(3)

else: Nil

setDimensions(newWidth) -->

Hello @jabrett 

Thanks for submitting this question. When defining setbacks, it is not necessary to use shapeO(). Please use the setback operation—ArcGIS CityEngine Resources | Documentation instead.

To create the T-shape  you also want to use the t operation—ArcGIS CityEngine Resources | Documentation to translate the scope after adjusting it's size.
