Adjust attribute dimensions based on split part

jabrett — Sun, 04 Aug 2024 06:58:53 GMT

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!

version "2023.1"

//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

shapeO(frontSetback,sideSetback1,rearSetback,sideSetback1) { shape: Border | remainder: Footprint }

split(z){ ~23 : Part("Front") | ~40 : Part("Rear")}

Part(name) -->

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

case name == "Rear" : setDimensions(6)

else: Nil

setDimensions(newWidth) -->

s(newWidth,'1,'1)

color("#FF0000")

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.
