Hi
Lot's of people are suggesting moving to Revit for very good reasons. As a non CAD user, I sat on both the AutoCAD and Revit 3 day training courses and I have to say, I actually found Revit easier. That probably had to do with the fact that I'm not good at reading 2D and working in 3D helped me train. Once you get used to the fact that it is essentially a database with a graphical interface, Revit wins hand down. I've just rented Revi for 3 months and I'm learning my skills through tutorials. I'm going to book onto a family creation course with my local reseller as families are the key to success with Revit.
Hope that helps
