Well, we got us a cell door this time, so you aren't trapped in there forever. You can get out for some dayroom, yard or chow... or maybe your prison job!
I think it'd be cool to get into making an isometric prison cell drawing, for more details... but I'm having fun reminiscing with a 2d drawing.
Benefits of making blueprints
Keeps me disciplined, even though last drawing was 2 months ago almost exactly.
Fun hobby
keeps me sharp
helps me learn more libreCAD (which can be a bit different in some ways from the softwares its inspired/derived from), as I prefer not to use bloatware
