I use shapr3d i can use shapr software for flat drawing for the sheetcam i use shapr3d for flat drawing for my cnc route table for the toolpaths and i use the shapr3d for my 3D printer. Fusion 360 is nice the price is a little high the shapr3d is $300 a year. The sheetcam is Reasonable and the carbide create for router toolpaths is free and cura split software is free for 3d printer. You can try the inkscape software me personally you just don’t have a good modeling in the software but it great for designing.
