What kinds of values can it pull?

Design loads, material grades, member sizes, capacities, and dimensions — whatever is written in the notes and schedules.

Can I export the extracted table?

Yes — schedules export to CSV/Excel, ready for your calculation tools or review register.

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.

The PDFDepth workspace with a drawing sheet open in the browser — The live PDFDepth workspace — markup, measurement, and review on one canvas.

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.
