Welcome to the Autodesk Forums!

Hi,

Sorry, but it is naerly impossible to describe all equivalent buttons on Mac compared to Windows, because there are a lot of them. At the same time all commands and their options (if you are using them from the command line) are absolutely identical.

About your other questions:

>>>He pulled up something called design center

- there is no Design Center in AutoCAD for Mac, so uou cannot use it.

>>>> He typed on his L@12' and could choose an angle for his line, but I had to drag mine.

- in AutoCAD for Mac you enter point coordinates the same way as in AutoCAD for PC - there is no difference. For example if you start LINE command and pick first point, than you can type @12'<40 to draw line with 12' length at 40 degree.
