Depending on what you intent to make you might want to look at freecad stepup (if you want to make complex precise shapes on copper for example to implement antennas, buttons, sensors, …) See Kicad StepUp: The Sketcher for Footprint generation
If your task is to make something artistic and you have your source material as a vector drawing then you might want to take a look at svg2shenzen
