How do I edit a local OSM map at 1:20000 scale and size 15x15 miles?

system · March 4, 2023, 2:00am

I am trying to create a paper map of about 4’ x 4’ of a 15x15 mile area centered on Winston-Salem, NC. I have downloaded both planet.osm and north-carolina-latest.osm, and tried to open the osm file with JOSM, Merkaator, Potlatch, Inkscape and one other editor I don’t recall. All of them process for varying lengths of time (usually several hours) and then die.
Once I have the desired area open in the editor I’d like to either (1) edit it by adding places of interest, etc., or exporting it to a vector format that I can import into Corel Draw.
I am not trying to edit the online version(s) of the files. I just want a local file so I can print tiles and assemble the map “old school” with scissors and glue.
I’d be happy with an interim step that further restricts the size of the OSM file, but can’t figure out how to “snip” a 15-mile square out of the OSM file.
I’m running in a Windows environment with 32GB of RAM and 250GB free space on my hard drive. I would load up a Unix box if there were a unix-only tool.
Thanks in advance for any help.
