You can attach information to blocks and later extract the information to create a bill of materials or other report.
To create an attribute, you first create an attribute definition, which stores the characteristics of the attribute.
If you have attached attributes to blocks, you can then query one or more drawings for this block attribute information and save it to a table or to an external file.
Using an attribute extraction template file, you can extract attribute information from a drawing and create a separate text file for use with database software.
