Good free technical drawing software for PC?

[RealKerbal3x]

I find it quite fun to do technical drawings of my KSP craft, but since I'm not that good with a pencil, the drawings never seem to come out quite as nice as I'd like. Does anyone have any suggestions for free technical drawing software for PCs?

I know that there's at least one available for mobile devices, but I don't think it would be very fun to draw on my tiny phone screen

I've heard good things about LibreCAD, but I don't use it myself.

If you're a student you could probably get AutoCAD on a student license for free for 3 years. Pretty fully featured cad program.

I used FreeCAD for a short while. It's actually quite decent for the cost (free as the name might imply), however, I returned to SolidWorks (which is, of course not intended to be free), but is a beast and just works for everything I threw at it. I don't remember if anything particular was wrong with FreeCAD, it's just that SW is so much better.

FreeCAD uses pretty much the same design philosophy as SolidWorks, which I find extremely intuitive. In contrast SketchUp (also free) is something I can't wrap my head around and find unusable. That being said, I've seen people making some impressive stuff in SketchUp.

All three of these are actually 3D, but they have no issues with 2D.
