3D building model automation
FalconTrace turns 2D architectural drawings into clean, zoned 3D models for building performance analysis, energy and daylight. Every value is traced to its source, and what the drawings don't settle is listed as an open question.
Under 2 minutes for most drawings, from DXF or DWG to a model you can open in your own tool.
Who it's for
Built for the firms that model buildings
Turning architects' drawings into model geometry is where much of a modeller's time goes. FalconTrace does that step for any firm, whatever tool it works in.
Energy-modelling consultancies
Zoned geometry for compliance and design models (ASHRAE 90.1, ECBC, LEED, GRIHA projects), checked before it reaches your tool.
Daylighting analysts
Rooms, windows with sill and head heights, skylights and shading devices in 3D, ready for your daylight workflow.
Green-building consultancies
Areas reconciled to the drawings, open questions for the design team, and a record of every assumption for reviewers.
How it works
From drawing to zoned 3D model
It works the way an experienced modeller reads a set of drawings, and shows its working.
-
Drawing in
DXF or DWG (vector PDF too). Layers, blocks and room tags are read; wrong units, frozen layers and missing xrefs are reported, not skipped.
-
Cleaned and zoned
Duplicate lines, gaps and stray blocks are cleaned up, rooms are traced to closed boundaries and grouped into thermal zones, with plenums and perimeter/core splits where they apply.
-
Built in 3D
Floor heights from the section levels, floors stacked, roofs, windows and doors placed, north from the north arrow, shading drawn on the plans included.
-
Checked and traced
A model check for closed zones, matched shared surfaces and floor areas. Every value is traced to its source: the drawing, a cited standard, or your decision.
Open questions, listed
An expert review raises what the drawings don't settle, why it matters and a question for the design team. Your answers are applied to the model, and an RFI register and email draft cover the rest.
Runs on your machine
A Windows desktop app with a command line for batches. Drawings stay on your computer. The optional AI assist runs locally by default and is only sent layer names and room labels, never geometry.
Exports
Into the tools you already use
One model, written for each tool. The geometry checks follow each tool's own rules, and files are read back after they are written.
| Format | For | What it carries |
|---|---|---|
| gbXML 7.03 | IES VE (gbXML import) and other gbXML tools | Spaces and zones, surfaces with matched adjacencies, windows and doors, shading, true north |
| eQUEST .inp | eQUEST (DOE-2.2) | Floors, spaces, walls and windows within DOE-2.2's limits |
| Rhino .3dm | Rhino | A layer per floor and zone, one solid per zone, openings |
| EnergyPlus IDF | EnergyPlus | Zones, surfaces, openings and shading |
| Reports | Your team and reviewers | Thermal zoning plans (PDF), zone schedule and assumptions log (Excel), WWR per floor and orientation |
Also written: the four Appendix G orientations. Import into each tool is being verified version by version; ask us for the current compatibility table.
NextModel inputs (internal loads, schedules, HVAC systems, weather) and running the simulation. Today FalconTrace delivers the zoned 3D model; you complete the inputs in your own tool.
See it on one of your drawings
Send us a typical project (a floor plan and a section) and we'll walk you through the model it produces, the open questions and where each value came from.
