AutoCAD 2D Design for engineers

Hello everyone,
My name is Yarin and I'm a civil engineer.
several years ago when I just started to work I needed to learn many of the principles and commands of AutoCAD by myself,
because there were no friendly guides over the internet, and nowdays new workers expirience the same thing.
so I'm here to offer my help and knowledge.

NOTE: i have no expirience in progreming, only design.
Best regards and good luck
