I have begun working through the Autodesk Revit BIM Lectures and Student Workbook. Thus far, the readings and exercises have been very helpful in understanding the differences between CAD and Revit along with explaining some of the basic commands found in Revit. I just completed Unit 1 where I created a small one-story house (see screenshot below). So far, using Revit has been a lot of fun and I enjoy how easily all of the elements come together. Definitely a breath of fresh air from CAD!
