The data extract command in AutoCAD (and AViCAD as well) makes it possible to create a BOM table from block attributes in your drawing using the DATAEXTRACTION command,

With this step-by-step tutorial, we’ll learn how to add and edit a bill of materials in CAD software. Understanding how to manage a bill of materials is important for CAD projects in industries like Piping, Ducting, and others that need to itemize their drawings.

The advantages of using data extraction include:

1. Speed advantage: The data extraction command allows quick extraction, significantly reducing the time and effort required.
2. Simplicity: The data extraction command offers a straightforward way to export to Excel, making the process much less complex than other methods.
3. Customization: You can choose and filter specific objects, properties, and attributes, resulting in tailored data output.
4. Integration: The exact method of extraction applies to AutoCAD. Also works directly with Excel
5. Flexibility: It allows you to use table styles and also link the table to Excel (DATALINK), offering even more versatility in how you can use your data.
