So I've written the cga rules up to the point were I have the basic facade the way I want it.  I did a split (x) on the floors to lay out the three sides of the bay window set up, but I don't know how to angle each side of the split so that it can actually look like a bay window.  Any advise would be appreciated. Thanks.

Hi Matt,
Here are images of the typical bldg types I am trying to model.

Hi, here's some code to get you started .. It shows how I would begin, when trying different things.
It's not the final thing you'd want to use, just shows you some strategies, ok ?

A screenshot :
[ATTACH=CONFIG]13838[/ATTACH]


attr Number_Floors   = 3
attr Floor_Height   = 2.8
attr Tile_Width   = 3.5
attr Relative_Bay_Height  = 0.5
attr Bay_Angle    = 60
attr Bay_Border_Thickness = 0.1
attr Bay_Border_Depth  = 0.12
attr Bay_Window_LowerHeight     = 0.8


Lot -->
 extrude(world.y, Number_Floors * Floor_Height )
 comp(f) {side : Facade | top : Roof. }


Facade -->
 split(y) {~Floor_Height : Floor }*

Floor -->
 split(x) {~Tile_Width : Tile }*

Tile -->
 30%:
  roofGable(Bay_Angle,0,0,false,0) # Reorient Roof vertically !
  split(y) { ' Relative_Bay_Height : alignScopeToAxes(y) BayWindowVolume(scope.sy) | ~1 : NIL }
 else :
  Facade.

BayWindowVolume(yDim) -->
 comp(f) {back : NIL | side : BayWindowSide | all : Rest. }

BayWindowSide -->
 alignScopeToAxes(y)
 split(y) {Bay_Border_Thickness : BayBorder | ~1 : BayWindow | Bay_Border_Thickness : BayBorder}

BayBorder -->
 s('1.10,'1,Bay_Border_Depth)
 center(x)
 i("builtin:cube")
 trim()


BayWindow -->
 split(y){Bay_Window_LowerHeight : Wall. | ~1 : BayWindowFrame}
 
BayWindowFrame -->
 offset(-.1)
 comp(f){border : Frame | inside : Glass.}

Frame -->
 extrude(.05)

Hey Matt! Thanks so much for posting the code.  I'm gonna play around with it and then post what I come up with.  As an aside, I was really happy to realize I actually understood about 90% of your script at the start!

hey !

great to hear !


let me know the specific technical questions first, we then can tackle the task of 'generalizing' the rules to create more variety in the actual building volumes. that's usually the more complex task when learning CE.

Is it possible to create a single roof that can cover the initial mass and the bay windows on the top floor?
