I recently used Fusion 360 to prepare a 3D model for the CNC. The CAM section in Fusion 360 allows you to export a .tap file that contains g-code (commands) for the router. Here is a tutorial that I followed.
However, for purely 2D projects Fusion 360 is an overkill I think, especially if you’ve never used it. I would draw what I need in Inkscape and import the vector graphic into VCarve, which will produce the g-code.
