How do I extract specifications, loads, and dimensions from engineering drawings?
Short answer
Run an extraction tool over the text layer of the drawings and specs to pull structured values — design loads, material grades, member sizes, and key dimensions — into a table you can review and export, rather than retyping them from general notes and schedules.
Where the parameters live
Engineering values hide in predictable places: general notes list design loads and criteria, schedules tabulate member sizes and equipment, and title blocks carry project data. The information is all there — the work is pulling it out of narrative text into a structured form.
Automating the extraction
The Engineering Parameters tool in PDFDepth reads the text layer and extracts values into a reviewable table. For schedule-heavy sets, Extract Schedules to CSV/Excel converts schedule tables on the sheets directly into spreadsheet rows. Both approaches beat retyping: fewer transcription errors, and every value can be traced back to its sheet.
Verify before you rely
Extraction reads what is written — if two sheets disagree, you get both values and must resolve the conflict. Always spot-check critical parameters against the source sheet, and prefer extraction outputs that cite where each value came from.
Key takeaways
- Loads, grades, and sizes live in general notes, schedules, and title blocks.
- Extraction turns narrative text into a structured, exportable table.
- Extract Schedules handles the tabular data directly.
- Spot-check critical values against the source sheet.

Not directly — extraction reads the text layer, so scanned sheets need OCR first.
