Welcome, I'm a long tine cad user and designer/drafter and find this cad system to be very useable, and the admins are really great about getting your questions taken care of....I just finished my first test project with this and yea, I had to change the way I was used to doing things but as I went along I actually started seeing why they did it the way they did and ended up changing for the better.
