Read the source
Keep drawing version, title block, location, and packet context attached before a row is treated as usable.
HEAD TO HEAD / 08 / CHECK BEFORE ISSUE
Excel vs AI BOM for drawing-to-BOM work
Compare spreadsheet takeoff with repeatable extraction across row entry, source linkage, validation, and handoff.
THE CHECK EACH ROW AGAINST THE DRAWING
A drawing is the starting point. A qualified reviewer must decide whether the row is complete, which source supports it, and whether it is ready for handoff.
Validate the row
Make missing parts, conflicting specifications, quantities, and reviewer ownership visible before export.
Handoff the BOM
Shape the output for procurement or fabrication while preserving the source and the decision behind every correction.

ILLUSTRATIVE VALIDATION PROTOCOL
Validate every extracted BOM row against the drawing
This worked example shows the review format. It is synthetic test data, not a customer result or a claim about product accuracy.
| Field | Expected source | Illustrative extraction | Reviewer action |
|---|---|---|---|
| Drawing reference | ISO-EXAMPLE-01 | ISO-EXAMPLE-01 | Accepted |
| Item description | 90° LR elbow | 90 degree elbow | Normalize wording |
| Specification | ASTM A234 WPB | A234 WPB | Verify against source |
| Size | DN100 | DN100 | Accepted |
| Quantity | 4 | 3 | Correct to 4 |
| Source location | BOM row 12 | Not captured | Add source location |
Method: define the expected row from a controlled source, compare field by field, record every correction, and report row acceptance separately from field acceptance.
