What Do the Catalog's Different Row Types Mean?
The topmost row is the Header row. This row contains hard-coded columnheads. The columnheads enable Compfire to identify and connect item metadata to specific Sketchup components. Do not edit any cell header cell. Doing so will break Compfire's features.
You are free to change the order of the columns.
Each main row represents an individual forged Item. These rows hold the item properties that enable and control Compfire's powerful features. This kind of data, data about data, is often called metadata.
Compfire will read each row's cells, and connect this item metadata to the corresponding Sketchup component.
