Hello,

Thank you for your reply.  
I would say that creating a setup for procedural street grid + city parcels or plot divisions (since in the city those are all connected) is the end goal here.  
I’m currently researching different ways to create procedural city and street layouts and I’ve read about L-Systems recently as a way of doing that so I wanted to test it.

In addition I wanted to learn more advanced things from geometry nodes system in Blender.

I did other experiments in “Works in progress” topic I created some time ago if you are interested:

> Hello, Recently I’ve been learning geometry nodes with the goal to create some tools for myself that would aid me in my work (environment design and concept art mostly). So I decided to put into practice what I learned so far and share the journey in hopes of learning something new and maybe helping other people by sharing the process with some insights that I have. So, I will describe the main idea and plan below. Here are my experiments with the city generator built from scratch in geometry …

I hope that answers your question. Thank you for your time.
