Can I capture BIM-style element data on a PDF plan?
Reviewed for technical accuracy by licensed professional engineers.
Short answer
The BIM Capture tool drops typed element pins on the sheet — door, wall, supplier, or fire rating — each opening a form of parametric fields (dimensions, materials, ratings, manufacturer) plus notes and photos; uploading a photo of the element AI-fills the fields, and the captured set exports as structured JSON.
What a BIM pin carries
Each pin is typed, and the type decides the form. A door pin asks for type, width, height, material, fire rating, and manufacturer. A wall pin asks for wall type, thickness, height, material, insulation, and fire rating. Supplier pins hold name, contact, and category; fire-rating pins hold the rating value, assembly type, and tested-assembly reference. Every pin also takes free notes and a photo set — the field record sits exactly where the element is drawn, not in a detached schedule.
AI prefill from a photo
Attach a photo — a door schedule row, a nameplate, a tag on the wall — and the BIM analyser reads it, filling the matching fields automatically: a door photo proposes the door type, dimensions, material, rating, and manufacturer. You verify and adjust before saving; the image stays on the pin as backup.
Pins that behave like annotations
BIM pins are annotations on the sheet: they render on the page, travel with the document, open for editing on click, flatten into exported PDFs, and sync to collaborators when the set is shared. Deleting or moving them works exactly like any other markup.
Getting the data out
Import & Export → Export BIM Data as JSON downloads a structured file — every pin with its type, page, position on the sheet, full field data, and timestamps. That is the handoff: a typed element inventory keyed to drawing locations, ready for a schedule, a spreadsheet, or a model-build pass elsewhere.
What it is — and is not
BIM Capture is element data capture on the drawing, not a parametric model: the pins hold the attributes a BIM object would carry, positioned where it sits on the sheet, but they do not become an IFC file. For the other direction — having the software classify walls, rooms, and devices for you — Identify Elements (BIM) produces a detected inventory; the two pair well: AI proposes, you pin the ones that matter with full data.

Key takeaways
- BIM Capture drops typed pins — door, wall, supplier, fire rating — with parametric fields, notes, and photos.
- A photo of the element AI-fills the pin’s fields; you verify before saving.
- Pins are annotations: they render, sync, edit, and flatten like any markup.
- Export BIM Data as JSON produces a typed, sheet-positioned element inventory — capture, not an IFC model.

No — it captures typed element data positioned on the sheet and exports it as structured JSON. The fields mirror what BIM objects carry, but the output is an inventory, not a parametric model.
