This video shows you how to create attributes and add them to a block in AutoCAD. Please refer to Tutorial 2-4 for more information.
As you learn more about them, you will find that attributes are a very powerful tool. Done properly, they will allow to extract useful information from your drawing and easily allow other non-CAD users to have access to the data in your drawing.
This is a great tool to master and make yourself more valuable as an employee.
