+1 for OnShape.  I am still learning it and I have not used it for something like a cabriole leg yet but I found it much easier to learn than Fusion 360.  Their free online tutorials are excellent and when I need to do something a little more complex, I can usually find a tutorial for the feature I need.  One great thing about it is the parametric approach makes changes so much easier than what is required with Sketchup.  You can usually go back to an earlier step, tweak a sketch and have later steps adjust accordingly.    And Free is good.
