Open source CAD software is basically useless. As someone who has tried every few years to use open source alternatives for personal projects, I always end up paying for an AutoCAD or Fusion 360 license.

My professional background has always been higher end software like Siemens NX, Solidworks, Inventor, & AutoCAD.

LibreCAD is the closest I ever got to something that seemed useful for 2D. I hate FreeCAD, QCAD, BRL-CAD, etc. Many open source projects waste so much time to do simple tasks and buck standard methodologies for their own spin on how they think you should design.
