I find that I’m more of a Fusion 360 person then Tinker cad person. Both are good cad programs both are free (well Fusion 360 is only free for non commercial use not sure Tinker cads license). Like Tinker cad, F360 has a lot of you tube videos & tutorials online to get you started. Both Cad apps are great! My suggestion is learn one and stick with it until it no longer meets your need. Better to be great at one then so so with a bunch of them.
