I want to play with CNC and don't yet have any experience with CAD software (nor the licence for the expensive ones) other than perhaps some Blender, so I decided to try to use the super ugly route with metapost -> svg -> dxf -> g-code for the first time.
For simple shapes I'd choose Inkscape SVG editor, which can export to DXF directly. In settings you can customize the coords precision to reduce those fractions. For more sophisticated designing I'd skip simple 2D CADs and use parametric tools instead (allowing to use equations instead of fixed values which simplifies future refactoring). I'd recommend Autodesk Fusion, which is even free for enthusiasts: https://knowledge.autodesk.com/support/fusion-360/troubleshooting/caas/sfdca... https://www.youtube.com/watch?v=VzqXo0d0W8s Jan
