Three steps, no account. Below: the file types it reads, what comes out, and — just as important — what it does not do.
Three steps
1. Say what you want. On the tool page, the right-hand panel is a list of Excel columns. Edit the names, and under each one write a sentence telling the AI where to find it: the unit, which corner of the title block, an example value.
2. Drop the drawing in. One file or a whole batch (up to 30 at a time). Extraction starts immediately and every step is shown while it runs.
3. Check the red cells, then export. Anything the checks could not confirm is filled in and flagged red with a plain-English reason. Fix it in the table, hit export, and you get a real .xlsx — red cells stay red in Excel, with comments.
What it reads
2D drawings: PDF, PNG, JPG, TIFF, BMP, WEBP. Multi-page PDFs are read page by page, up to 10 pages per file — past that the extra pages are not read.
3D models: STEP / STP. Bounding box, face count and solid count are computed straight from the geometry, so those numbers are arithmetic, not a guess. The file and its geometry never leave our server; only your column names are sent to a language model, so that it can match them onto the quantities we computed. It never sees a value and never supplies one.
Parts lists: when a drawing carries a bill-of-materials table, each row of that table comes out as a row in the Excel file.
What it does not do
No native CAD files. DWG and DXF are not read. Export to PDF from your CAD program first — that works well.
No GD&T extraction. Feature control frames, datums and geometric tolerances are not parsed. If you need those, this is not your tool today.
No part volume from STEP. A bounding box is not a volume. The tool says so on the cell instead of quietly giving you a number that is wrong.
No weight from a 3D model. A STEP file carries no material density, so the weight column is left blank and marked, not estimated.
Why the red cells matter more than the accuracy number
A wrong value that is the right order of magnitude is the dangerous one — nobody re-checks a plausible number. So every value that fails a deterministic check (unit mismatch, a number that is not a number, a value that contradicts the text the model quoted) is filled in and turned red with the reason attached. The flag travels into the exported Excel too.
