Color by Land Use

Hi Guys

I´m newbie in CGA.

I tried apply Color in (2D) Shapes based on Land Use atribute. I use 3DCIM_Parcel_Zoning Envelopes.cga as a sample, but this CGA change my geometry (Angles)

I need a simple CGA sample for apply a Color based on attribute, without geometry operations, just change colors.

This is a simple rule example. One attribute determines color. That color is shown in the other attribute, YourColor, and that color attribute can be overridden by the color picker on that attribute.

Chris

version "2014.1"

@Range("Go", "Caution", "Stop")
attr DeterminesColor = "Go"

@Color
attr YourColor = theFunctionThatGivesColorPerAttribute

@StartRule
ColorMeMine -->
  color(theFunctionThatGivesColorPerAttribute)

theFunctionThatGivesColorPerAttribute =
  case DeterminesColor == "Go": "#00FF00" #Green
  case DeterminesColor == "Caution": "#FFAA00" #Orange
  case DeterminesColor == "Stop": "#FF0000" # Red
  else: "#000000" #Error! Picker value unknown. Use black.
