I took an architectural design course that required the "Essentials" book, but that book was frustrating because of the gaps in its step-by-step instruction. After a couple discouraging weeks, I bought this book by Daniel Stine and actually started learning how to really manipulate Revit. The project in this book is much easier to understand, and the included videos show exactly what's expected. I've had over a decade of 2D experience, but 3D was completely new to me. Now I know how easy it can be. I highly recommend this book & DVD.
