Custom grow streets in cityengine

Question asked by kru_99 on Dec 27, 2019

Are there CGA rules for the grow streets methods?  I assume I can just make an entirely new CGA or python script to generate a city, but its a little much. I would like to just modify the rules that already exist within the grow streets method, or use it as a template.  For example, I wanted to make a rectangular city and when changing the parameters for long and short streets to be constant, it still would skip some connections.  Or Instead of random angles I want it to follow a specific angle over time, etc.  When I run the grow streets, I only see 4 settings under Layer Attributes and can't find any other scripts.  I am really looking for a template for my own grow streets feature, but just to explain the issue with the rectangles I also attached an image showing the problem.
