3D PDF Tutorial For AutoCAD 2016/17/18

[omorah]

I have been looking for a more current ( AutoCAD 2016/17/18 ) 3D tutorial in PDF. I have a handful of AutoCAD 3d tutorials, but they are for older versions with different functions than the current versions of AutoCAD. Yes, all 3Ds may have same concept but with newer versions of AutoCAD (toolbars), it would be nice to have a more current PDF tutorial. Also, yes, there are tutorial videos, but I would also like to use a PDF to learn/practice 3D drawings.

Thank you!

I found a solution for my request, so, I would like to suspend the original post.
Thanks.
