I want to create a city model similar to the ones on Maker World like this one: New York City Midtown Manhattan Mini v2 by jarvizar - MakerWorld
I want to make a custom model of my neighborhood, specifying an exact area of buildings and streets. I was able to create an STL of this in Blender using data from Google Maps - you can access it here.
But that model won’t print, because it is full of non manifold edges. I’ve tried several STL repair softwares but none can fix it. I suspect it’s not fixable because the Blender/Google Maps process is not designed for printing and it leaves hundreds or thousands of non manifold issues in the model.
So, I wonder what other methods there are for creating these type of city models for printing, allowing for specific locations.
I appreciate any advice - thanks!
