Dear all
I try to wirte a cga rule for underground utilitys, especially pipes. I give the objects following information:
Height: VPKOTE
Radius: Radius
Form: Model of Pipeline
Nutzungsart: Type of use (sewage, fresh water etc) which should be displayed with different colors
I don't understand why CE won't take the values out off the attribute table and colorize it...
This is my rule:
version "2018.0"
// Attributes
attr VPKOTE = 0
attr Radius = 0
attr Form = ("Pipe")
attr Nutzungsart = 0
// Functions
red = "#ffaaaa"
green = "#00ae00"
blue = "#aaaaff"
turquoise = "#ooebeb"
white = "#ffffff"
yellow = "#ffff73"
grey = "#9c9c9c"
// Start !
@StartRule
LOT -->
extrude(world.y, VPKOTE)
extrude(Radius)
color(Nutzungsart)
color -->
case Nutzungsart == 1 : color(red)
case Nutzungsart == 2 : color(green)
else : color (yellow)
PipeAsset =
case Form == "Pipe" :
"assets/pipe.obj"
else: "assets/pipe.obj"
I appreciate any help and tipps!
Thanks in advance

Hello Chistoph
In your code you used "color" as a rule name. Additionally it is also a CGA operation
http://desktopdev.arcgis.com/en/cityengine/latest/cga/cga-color.htm
I advise you to rename the rule to "setColor" and do not hand over the attribute "Nutzungsart". This should do the trick:
version "2018.1"
// Attributes
attr VPKOTE = 0
attr Radius = 0
attr Form = ("Pipe")
attr Nutzungsart = 0
// Functions
red = "#ffaaaa"
green = "#00ae00"
blue = "#aaaaff"
turquoise = "#ooebeb"
white = "#ffffff"
yellow = "#ffff73"
grey = "#9c9c9c"
// Start !
@StartRule
LOT -->
extrude(world.y, VPKOTE)
extrude(Radius)
setColor
setColor -->
case Nutzungsart == 1 : color(red)
case Nutzungsart == 2 : color(green)
else : color (yellow)
PipeAsset =
case Form == "Pipe" :
"assets/pipe.obj"
else: "assets/pipe.obj"
