I've use to be in the engineering field, so design, parametric modeling is no biggy. I like to see/hold what I create so 3d printing is amazing. No 2d only BS. Started with Autocad 13 then upgraded to solidworks, solidedge, UG, ect. Fusion 360 is amazing. I also dabble in woodworking.
I love how I create create stuff I can actually use.
