Field notes
- The Master Modeling Technique
A top-down, multi-body SolidWorks method — build every part in one master file so geometry and drawings update automatically through push/pull operations, and mates never break.
- Constitution of the United States — Renewed
A rewrite of the U.S. Constitution for the problems the founders couldn't have imagined — rights, representation and accountability, written from scratch.
