Questions on this?
Reference values, not a design.
Values are the nominal figures of the cited standards, or calculated from them where marked. The governing standard and your drawing always take precedence.
Questions buyers ask.
Which drawings work?
Mechanical and structural drawings that carry a printed parts list, bill of materials or bolt schedule, as PDF or DXF, and parts lists as XLSX or CSV. Up to 5 files and 10 pages per drawing set. The table must be legible: the clearer the print, the better the result.
How accurate is the takeoff?
Printed parts lists, BOM tables and bolt schedules are read reliably, and each row shows the file and page it came from. Counting parts from the views themselves, without a table, is not done yet. The list is generated by AI: check every line against the drawing before you order or quote, and use it as a starting point, not as the governing document.
What happens to my files?
Your files are sent to AI service providers in the USA only to extract the parts list. They are not used to train AI models and are deleted after 30 days. If you unlock the full list, we keep your name and business email with the takeoff so our sales team can follow up. Details are in our privacy policy.
What does it cost?
Nothing. The tool is free for 2 drawing sets a day per visitor, up to 10 pages each. The first 5 rows show straight away; the full list and the Excel file need your name and business email.
What is a bolt schedule?
A table on a structural or mechanical drawing listing each bolt group with its size, length, grade, standard, finish and quantity, often with matching nuts and washers. The takeoff turns it into order lines, for example 200 × M20x80, ISO 4017, 8.8, HDG.
