Hello

Excuse my bad english

I'm working on a urban model derived from the town planning regulations.
I required to establish differential distances between the boundary of parcel and the limit of each side of the building
I tested with the offset command but applies the same distance from all faces, but I need to differentiate between the face and apply a distance

What command should I use, or what is the proper rule?
There is some learning resource CityEngine in Spanish, or any forum in this language?

I appreciate any help. Thanks.

You can use the setback operation, in a recursive manner.

I think any solution depends on some more details of your problem...
The solution I provide bellow does not seem very elegant, nor it works in every situation... but it might get you going for now... :)

version "2011.2"

attr buildingHeight = 10

attr buildingColor = "#4A708B"

attr leftColor = "#FF0000"
attr rightColor = "#0000FF"
attr backColor = "#FFA500"
attr frontColor = "#800080"

attr frontSetback = 2
attr leftSetback = 8
attr rightSetback = 4
attr backSetback = 10

@StartRule
LotInner -->
    NIL.
   
@StartRule
LotCorner -->
    NIL.


@StartRule
Lot -->
    setback(frontSetback){
        front: color(frontColor) FrontPart.|
        remainder: MinusFront
    }

MinusFront -->
    setback(leftSetback){
        left: color(leftColor) LeftPart.|
        remainder: MinusFrontAndLeft
    }
MinusFrontAndLeft -->
    setback(rightSetback){
        right: color(rightColor) RightPart.|
        remainder: MinusFrontLeftAndRight
    }
   
MinusFrontLeftAndRight -->
    setback(backSetback){
        back: color(backColor) BackPart.|
        remainder: MinusFrontLeftRightAndBack
    }

MinusFrontLeftRightAndBack -->
    Mass

Mass -->
    alignScopeToAxes(y)
    extrude(world.y, buildingHeight)
    color(buildingColor)
    Mass.


I don't know any documentation in spanish though :S
I normally use the application help menu window, and this forum :)

Hope it helps!!
