Anthony,
As others have posted Draftsight is okay but not, dare I say, as good as Autodesk. I use it just to check out files that I have exported or intend to reference into VW Landmark. If you do decide to sign up for service select with VW there support staff is always on top of things and they are very helpful. Heck I even try to stump them and can’t.
I’ve assisted other firms with training and migration from Autodesk to VW, so if you do decide to move on from the old and into the new let me know. Best of all you will save money as you will not need to maintain sketchup or Rhino as with 2016 you can everything those packages do and in some cases better.
Good luck with the practice!
