From CAD file to 3D venue in seconds

No conversion tools, no plugins. The whole pipeline runs on your machine.

01 Drop in your DXF

Straight from AutoCAD, LibreCAD or QCAD. Layers are parsed right in your browser and the 2D plan appears instantly.

02 Walls are detected & extruded

Wall and glass layers rise into 3D. You choose which layers go up, while doors and stairs stay drawn on the floor.

03 Furnish, measure, annotate

Draw booths to size, drop desks and kakemonos, measure in meters, paint arrows. Everything syncs live with your team.

Everything you need to plan a venue

Built for event teams working on real buildings. Fast, precise and collaborative.

creator's note
01 · the file

I built this app because I could not even open our event venue's floor plan.

The venue sent us their floor plan. My PC could not open it. It needed a special CAD application. Hard to find, harder to learn, and even then I could not put a single note on the map.

02 · the struggle

Planning an event should not require CAD skills.

Decorating, assigning rooms, discussing live with the team, even zooming in on a call. All of it was a fight with the file.

03 · the fix

So I built the tool I wished I had.

Nothing to install, nothing to learn. Drag the venue's real file into your browser and plan together, live.

Now you have Architect3D. A tool for EVERYONE.

Organizers, venue teams, decorators, volunteers. If you can drag a file, you can plan a venue.

Try it with your own building

Your file never leaves the browser. Parsing and rendering happen locally.

Drop your .dxf floor plan and it opens in the app

Exported projects (.arch3d.json) work the same way. You can also click here to pick a file.
