CAD rookie buys Rhino
My background; My work history was concerned with sophisticated mechanical devices, and I am an electronics/computer hobbiest, but I had zero experience with CAD.
When the need came along to use a CAD program, I asked around knowlegible folks and was pointed towards Rhino. I did the Rhino tutorials and was off and running. With no classroom training in CAD of any kind, I thought it wise to buy as much Rhino reading material as I could. I got books from Amazon, and I bought Rhino Training Manual 1. There are DVDs associated with all these publications which makes self teaching easy.
The Rhino Training manual stands head and shoulders above all the rest, being easy to understand and to the point. With the training manual to the side and my computer screen in front of me, I play with the lessons in the training manual and the Rhino program, it is fun.
I find Rhino very do-able.
