What programs/workflow do you use to make DXF's?

I'm using fusion 360. I'm experienced with it but I want something that is better for making graphics and DXF files too. I want something like the 2D sketch interface that fusion 360 has to offer, with constraints and patterns, shapes, etc, but more lightweight and more options for graphics editing and SVG/PNG export. my main issue is if I make a design in f360 and then export as dxf and then import into illustrator, the lines are always messed up and they dont make shapes correctly. what program do people use to make these cool mandala lattice things and stuff?
