From SAT + IES to a verified Revit family.

BIMMER turns your luminaire’s CAD solid and IES photometry into a ready-to-place Revit lighting-fixture family — light source positioned to the millimetre, aimed correctly, and carrying the manufacturer’s real photometric data. No Revit licence needed.

No card, no Autodesk account, no CAD add-in to install — everything runs on BIMMER's own cloud. Convert real fixtures and keep the files.

How it works

No Revit seat, no CAD add-in to install, no family-editor expertise, no manual typing of photometric data.

Upload

Drop two files: the SAT model and the IES photometry. Add rows to convert a whole range at once.

Convert & verify

A cloud Revit engine builds the family and four gates verify it before delivery.

Download .rfa

Load it straight into your project — light source, photometry and datasheet already set up. Nothing to do in Revit.

Your Bim Library

Every conversion is saved with its source files. Re-download or re-issue an updated version any time.

From your CAD tool, into Revit

SolidWorks, Inventor, Fusion and Rhino document ACIS .sat export routes; other systems can use a neutral-format intermediary. BIMMER does not upload native CAD or STEP directly. No BIMMER add-in is required in your CAD software: simplify the model, export SAT 7.0/4.0, pair it with IES and Generate.

Product names identify source-file preparation routes only. BIMMER is independent and is not affiliated with or endorsed by these CAD vendors.

Four rules for the CAD file

BIMMER reads what you already have — but how you export it decides whether the family comes back right. Each rule takes a minute, and together they are the whole of the preparation.

Export at ACIS version 7.0 or 4.0

Revit only reads older ACIS — a modern SAT (SolidWorks' default) won't import at all. In SolidWorks: Tools → Options → Export → ACIS, version 7.0 or 4.0, output Solid, units mm.

Model the light-emitting body first

Build the part that emits light before any other body, so it sits at the top of the model tree — that is the body BIMMER binds your IES to. Already modelled? In SolidWorks you can simply drag it to the top. Orientation is handled for you.

Keep the model simple

Ideally, remodel the fixture as a simple, compact version. Or use your product model and delete the small internal parts — screws, springs, wiring — it doesn't need. A heavily detailed model can arrive in Revit with broken geometry.

Keep the parts as separate bodies

When exporting, leave "write multi body part into a single ACIS body" unticked, so each part stays its own body. The family then keeps the heatsink, bezel and light individually selectable in Revit — your existing geometry tree, part by part. A merged model still converts — as one single part.

SolidWorks ACIS export options: version 7.0, Solid output, millimetres, single-body box unticked

Rule 1 — SolidWorks Tools → Options → Export → ACIS: version 7.0 (or 4.0), Solid, Millimeters, and the single-body box left unticked ACIS export settingsfigure coming soon

The light-emitting body sitting at the top of the CAD model tree

Rules 2–4 — the light-emitting body at the top of the tree, a simple compact model, and Solid Bodies(3): the parts kept separate, not merged Model-tree diagramfigure coming soon

Worried you'll have to remodel your whole catalogue? You probably won't. Keep your existing CAD models — simplify them as Rule 3 describes, and they will still convert. Not sure? Send one file to jiq@bimmer.lighting and we'll tell you exactly what to change.

Stop paying for BIM files

Lighting manufacturers: your clients and lighting designers ask for Revit families. You already have everything they need — the CAD model and the photometric report.

No BIM agency

Agencies charge per family and take weeks. Convert your own catalogue in minutes, whenever a product changes.

No Revit licence

A Revit seat costs thousands a year — a Family Editor expert costs more. BIMMER runs Revit in the cloud for you.

Verified, not guessed

Anyone can generate a family. Four checks measure every one: size, aim, placement, and the real lumens, CCT and watts.

A whole range at once

One row per product, every model paired with every IES. Forty families come back as a single .zip.

Schedule-ready data

Product code, CRI, beam angle, IP rating, cut-out, finish — shared parameters that schedule and tag like Revit's own.

Part-separated output

Every part is kept separate, each with its own material.
