I have a handful of tutorials on AutoCAD 3D PDFs. The latest version I have is 2007. I have Googled a lot. Would someone know where I can find a 'good' tutorial on 3D, on a more recent version of AutoCAD as possible. Yes, I know nothing has really changed much with respect to the process, but am sure the newer versions of AutoCAD might have shortcuts to functions. A fairly comprehensive PDF would be great to have and practice with.

I am currently using AutoCAD 2018, Civil3D 2018 and Revit 2018.
