For those who love diving in deep, CompassCAD is a (cough cough, let me repeat that again) non-parametric, open source 2D CAD software. I purposely placed it on competition against AutoCAD, because competition and rivalry are both fierce. It is heavily based on a custom CAD framework I forked from WebCAD5 (in which the modified framework is released as CompassCAD Core) and Sunset UI (it's a scrapped project but it had the good looking UI I wanted, so basically, it's a bootstrap code for UI essentials for desktop apps I make). The entire framework itself was fully optimized by making heavy use of Electron's API so CompassCAD can fully interact with the system and deliver that same natural experience.
