Any drawing.
A real Revit family.
PDF, DWG, DXF, image or spec in — a fully parametric .rfa out. No Revit license. No manual modelling. No waiting days.
Three stages,
one round trip.
Upload a design file. Watch the AI read it. Download a real parametric Revit family. Every step lives in the browser.
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.
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,

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.
