OSM Website
Now we are gonna visit OSM map website
It should look like this
Locate search bar in top left corner and for the tutorial purposes you can type Skoda M18 (Škoda production buildings in Czech Republic)
Your window should look like this
In the center of the screen is our desired building but we wanna surroundings too, not just the main building
Zoom out and position view so the main building will be roughly in center
Now we gonna define desired area and export map so click on Export button in top right settings
Than we wanna click on manual area selection instead of automatic one
You should see new brightened square pop up on map
Now we can define desired area to be exported. See image bellow how to Scale and Transform area

Blender part

Click on folder icon and locate generated map.osm
Now we need to uncheck things we don’t want to import
...
Select all Curves, press F3 and search for convert to mesh
After converting please join all roads, footways, railways and similar paths into the one single object
After that you should have 2 objects - Buildings and Roads
Rename it if you like
Delete all OSM Materials and create one for roads and one for buildings
Now we optimize little bit. Select all buildings in Edit - Face mode and Merge close vertices by 0.1
Next thing to do is splitting buildings via separate by loose parts function
Last thing to do is cleanup. You can delete associated curves in way_profiles folder since we don’t need them anymore
