Hi William,
How long have you actually used AC? If it's only a few months, then you'll have to give it some time. I came to AC after many years in the 2D world and, just prior to the switch, was using Skethup for 3D and vanilla AutoCAD for general draughting. For quite a while, I was so slow with AC that I was often tempted to switch back for urgent drawings. Resist that temptation and soon you'll be happier for it.
Working as a one-man-show with nobody to do my draughting, I find that I can complete my drawing work much faster and (more importantly) with greater accuracy. This, in turn, helps me take on more projects than I would otherwise have been able to handle.
This is not to say that I've completely abandoned 2d work - or sketchup either. But I've hardly touched either of them in quite a while.
Hope this helps.
