Hi Maziar, I am still not quite sure what exactly you want to achieve. I found your script rather obtuse, so I made another script from scratch. First I tried using the setback operation, as it allows to respond to real world orientation (north, south, etc.), using the world.north, world.south, etc. selectors, as this was part of your script, without having any relation to the actual corners of the world. However, it lead to problems on irregular blocks (start shapes), similar to the ones you describe (I couldn't reproduce them from your script, as I didn't have your shapes).
Long story short, I used a much simpler approach with simple splits, as you can see in the script below. Basically it allows you to
- Mirror the lots along the two long edges or not
- Rotate the split direction to possibly fit better with irregular blocks
- Align buildings along or across the direction of the street
- Position the buildings left/back, center, or right/front on the lots
- Keep a uniform height for all buildings or vary the heights within a min and max height
Check out the visuals below.
Rather than working from a ground cover ratio for buildings (which I think you do), I simply used a uniform building width, which can be set. I also used the InnerRectangle operation to make buildings rectangular, even on irregular lots.
Maybe that's not what you want/need, but I couldn't easily analyse your script 🙂. Nonetheless, I'm sure that you can draw inspiration from my script (below) and/or edit it to suit your needs. You may also wish to add some padding around the buildings, to avoid that they develop back-to-back.
