Not directy, but in
..samples\scripts\Logic there are some BOM script examples
eg Bill of Materials to Excel.bas
You can modify that to be sheet-conditional, and generate your BOM that way.
To speed this, you can use the PADS Logic Script Wizard.bas to create a sheet-scan example,
You will get a script that reads like this, showing the semantics of sheet scan and naming.
For Each aSheet in ActiveDocument.Sheets
Print #1, "Sheet: "; aSheet.Name
I'm not sure if this is what you are after, but if you only want the BOM for page 4-5 you can delete pages 1-3 and 6-8 and then run a BOM report.
