I think the best way is to try. It is nothing complicated in creating attributes. For making an first example, do this:

1) In the <Tools> menu, chooser < Define attribute>. Here you can create an attribute

2) If you want to modify the attribute, use <Modify> <Properties>

3) Create a block, containing attribute(s) and, if you want so, other entities (lines,..)

4) Insert the new block, on the comand line you will be prompted to enter de value for the attribute

5) Use <Tools> <Edit Block Atributes> to edit the attribute


You will see that it is very easy, hope yo will enjoy attributes.
