+1 for Fusion 360.
The learning curve wasn't too bad, what I learned can be used for 3D printing and CNC cutting, it is free, runs on macs, has easy online sharing and backup, designs are available on the phone with A360, it is parametric which allows for changing imensions by simply changing parameters, etc, etc.
I learned Skethup before I found Fusion and they are in different leagues.
Didn't know about this....pretty cool. Basically if you're "non-Pro" it's perennially free.
