Usually, some construction or decoration companies will require skilled CAD when recruiting. How proficient is it?

It seems that it is not common for architectural decoration companies to use CAD to make three-dimensional.

Familiarity means mastering all kinds of commands, and don't look for a command to turn over the menu for a long time; Which commands can be used for the fastest modeling of different components? You know, don't take the picture apart bit by bit in the most stupid way; I suggest that you master the commonly used shortcut keys (such as line, offset, label, ranging, padding and attributes ...), which will make the recruiter shine, and it is also the best explanation of "mastery", O(∩_∩)O~
