01Input

Input · your file

PDF, DWG, DXF, image, or text.

Drag any engineering drawing into the browser. No Revit license required, no plug-in to install. The file is converted to an image the LLM can read end-to-end.

02Idle

Extract · LLM → JSON

Our Custom LLM reads the drawing.

A multimodal model pulls out geometry, members, and parameters and emits strict JSON. APS Design Automation then drives a headless Revit to compile the family.

Output · download

Preview, tweak, download.

Rotate the 3D model, edit parameters live, then download as .rfa — or export to IFC, glTF, OBJ, DWG, STEP. It's already in your BIM pipeline.

Parametric by default.

A compiled .rfa comes back in 30–90 seconds, renders in-browser via the APS viewer, and exposes every dimension as a live parameter you can edit before download.

Element take-off,
in a few clicks.

Drop a Japanese structural drawing. Tag the legend and the plans. Get a grouped quantity schedule with per-page counts — and an Excel report you can hand to QS.

Structural take-off

EstimationAI.

A guided five-step flow that reads structural sheets and returns the quantity schedule.

  • Tag legend & plan sheets

    Render every page in the browser. Pick the 符号 list, then the 伏図 plans.

  • Per-floor counts

    Symbols are aggregated with vertical-continuity rules — peak floor wins.

  • Excel take-off

    Summary sheet, per-page schedule, category subtotals, and a grand total.

Whatever you have.
Whatever you need.

The pipeline is format-agnostic by design — anything a drawing lives in on the way in, anything a BIM pipeline consumes on the way out.

Questions,
answered.

The short answers. The long ones live in the docs - which are also free.

No. The .rfa compile runs on headless Revit via Autodesk Platform Services — no seat, no install, no plug-in. You open a browser and upload a file.

Today: PDF, image, and text specification. MVP adds DWG and DXF. The file is converted to an image and the LLM extracts geometry, members, dimensions, and annotations into a strict JSON schema.

Live today: structural. On MVP: structural + architectural. On the roadmap: scaffolding (highest demand), mechanical, electrical, plumbing, and multi-format output (Archicad, SketchUp, AutoCAD).

Accurate enough for parametric family generation — we currently use Qwen 3.5 with fallback models via OpenRouter. Every generation includes a 3D preview so you verify geometry before spending a credit.

Preview is free. You pay per-family only when you download — under $1 for structural, $0.50–$5 for everything else. No seats, no subscriptions. Credit-based, unlimited users in your org.
