If you are planning 3D designs, Fusion360 takes a bit of getting used to but is extremely powerful.

You can register for a free hobby license for the scaled down version, or a free educational license of the full version. It has good CAD capabilities and on the CAM side can generate g-code for 3D printing and CNC, or else allow you to export STL models direct to a slicer.
