It is my first time using GN. I am in a draft phase of a project, and I thought to learn GN in this specific project. I believe it will enable me to have a more flexible process.
I want to mock up a small city on a thickened disk; the main goal is to find a modular grid to place my buildings. I am not aiming to build the scene in GN but to find how many blocks I should use, so this is just for me to draft the right proportions, and then I will jump to model everything the "old school" way.
Summing up: I want a flat cylinder (my city land), and I want to create from that cylinder an outer ring to boolean a grid, working as streets, that I can scale up or down.
I started by myself, just searching for nodes and googling a bit:
Above, you can see the ring and node setup. Then I will Join the Center disk to make it visible and use the ring as the boolean of the streets/grid.
I added a subdivision just to check that my mesh is closed, preparing it for the boolean phase. I added a merge to distance, but I can see the subdivision node keeps reading the mesh as two separate entities. I am sure I miss some kind of node before my merge to distance.
Can you help me to figure it out?
Also, I would like to keep this post open to ask coming doubts when I lay my streets on the cylinder. Do I need to create a new post, or can I keep expanding this?
