Aligning a facade index to a cardinal direction

[LR]

Hi.

I'm creating a few generic buildings with the same rule — it splits a four-sided block into front, sides and back and textures them. However, as can be seen below, that doesn't always work as the index seems to start randomly(?) on any side.. my current solution are four copies of the script that roate through the four sides, but it's pretty annoying. Is it possible to assign the facade index 0 to, say, north?

Hi,

an index can not be set to north or so.

don't use an index for this .. familiarize yourself with the 'first edge' (see help files / manual) and just use the component selectors.

Thanks.

Not sure if I correctly applied it, but this is what  I came up with - might as well post it.

version "2014.0"


attr direction = "N" # N, E, S, W
attr roofindex = 0 # 1, 2


Lot -->
  case direction == "N": NorthBuilding
  case direction == "E": EastBuilding
  case direction == "S": SouthBuilding
  case direction == "W": WestBuilding
  else: NorthBuilding



NorthBuilding -->
  cleanupGeometry(all, 0.5)
  extrude (4)
  comp(f){
  world.north: front | 
  world.west: right | 
  world.east: left | 
  world.south: back | 
  top: top
  }

Here is one that might help you. Use whichEdge to rotate the "front" to any edge. -Chris

version "2014.0"  


@Range(0,10) # Range loops modulo style if more than edge count.
attr whichEdge = 0


Lot -->
  # Flatten shape to world xz plane: 
  alignScopeToAxes(y)
  s('1,0,'1)
  # Align scope to edge specified by whichEdge attribute.
  alignScopeToGeometry(yUp, 0, whichEdge) 
  Building 


Building -->  
  extrude(4)  
  comp(f){front: Front | right: Right | left: Left | back: Back | top: Top }
  
Front --> color(1,0,0)
Right --> color(0,1,0)
Left --> color(0,0,1)
Back --> color(1,1,0)
Top --> color(1,0,1)

Thanks - I ended up using my rule because it allowed bulk alignment and used your suggestion for the roofs since they didn't accept world.*.

However now I'm looking for a way to do that - fixing wrong roof(s) is pretty time-consuming in large areas.. any idea how to align the roof to cardinal directions? This is how it usually looks like when I generate a row of buildings:
