I use AutoCAD Architecture (ACA) at the office, but I'm a throwback to AutoCAD with Archt Addon for projects from the home office. I envy those who have switched to Revit. I identified Revit has the program for my future long before Autodesk bought Revit. AutoCAD Architecture was forced on me when I quit my sole proprietorship and went to work for a developer. After 5 years of ACA, I still insist on using Archt for projects from the home office. I am much faster with Archt. Economically, it hasn't made sense to crossgrade to Revit, but I'm getting to a point in my career where I still would like to, but the idea of learning new software is intimidating. In the late '80s and early '90s, I was probably the most technical minded person at firms I worked for prior to AutoCAD adoption.
My first CAD program was a program for the original Amiga 1000. I dabbled with it from home, but never used it on a project. I had no way of printing. My first computer rendering was also with the Amiga. That rendering was pretty crude by today's standards, but it impressed my employer enough that they shared it with the client. It was done at home on my own time just for the fun of it. Unfortunately, I don't find time to do things for the fun of it anymore.
