Creating a U or L shape on another shape

DavidKenley

Hello,

I have the following code for creating a U shape, I'm attempting to essentially extrude a cube, and add a uShape on top using comp(f).

I have attached two images, if I use my start rule as "RoofTier" it creates a ushape no problem. If I use my start rule as Lot, it will extrude my lower part of the building, but the u shape is incorrect. This also happens to L shapes. Note I'm just using the "Null" rule in this case to make my floor/ceiling planes.

Does anyone have any insight? I know from images I've seen this is very possible.

Thanks!

David

version "2012.1"

attr myFrontDepth = 5
attr myRightWidth = 5
attr myLeftWidth = 5


Lot -->
    extrude(20)
 comp(f) { top : Roof | all : Null}
  
Roof -->
 Null
 RoofTier

RoofTier -->
     shapeU(myFrontDepth,myRightWidth,myLeftWidth) { shape : Footprint | remainder: NIL }
     
Footprint -->
    extrude(20)

Thank you! Just ran into this problem trying to make a typical "five over two" podium building.
