I spend a lot of time on the internet, also, but its researching new builds / what people are doing / etc, so 'fun' stuff hahaha
I wish I did autocad though, I loved doing that shit in college, and was so relaxing. I designed an entire neighborhood from scratch, with sidewalk lines, etc etc
You gotta know your market.
I took autocad classes in college for fun. My degree typically doesn't require it. I ended up getting a job doing autocad stuff, and not what I went to school for lol.
I use autocad 14 and 2000. Not 2014 revision, but revision 14, i.e. pre-2000 lol.
Also have a newer program I haven't fully set up yet as its not fully compatible with our drill room yet. Still transfer data back to the old autocad for our custom add ons.
