EX3D Studio · architecture in the browser

Draw it. Build it.
Render it.

Plans, a live 3D model, photoreal renders and boards — in your browser, nothing to install.

Example scenes

Open one. It is live.

Walk through, change the sun, render. “Edit a copy” gives you your own version — the original stays as it is.

Or start fresh

Design a building

A plan with the Wall tool ready.

Render a model

Bring a GLB, FBX or DXF.

Make a presentation

A board, export PDF or PNG.

60-second tour

How a project comes together.

Inside

A serious tool, light on its feet.

A real path tracer

Unbiased GPU path tracing checked against physics, AI denoising, a calibrated sun and sky. The light is kept in 32 bits, so you can grade a render again later.

Weather

Clear, hazy, overcast, misty, foggy. Clouds, ground fog and light shafts, the same live and in the final render.

Drafting

Walls, openings, roofs, stairs, zones and schedules. Typed lengths, a tracker, snaps.

Landscape

Thirteen tree species with photographed leaves, lawns with clumps, seed heads, ferns and fallen leaves.

Interiors & furniture

Families for doors, windows, fixtures and classic furniture. Walk through at eye height.

Built for AI

A documented Agent API. The Farnsworth House was modelled through it, one instruction at a time.

Together

Design with your team, and with AI.

Architecture is teamwork. EX3D is built for it: one model, many people, live — and any AI model you choose as one more colleague.

Live collaboration

  • Co-editing, live. Everyone's changes appear as they happen — no "save and reload".
  • Reservations. Nobody drags what a colleague is dragging.
  • See each other. Cursors on plans and sheets, avatars walking the 3D model.
  • Talk. Chat, shared notes, audio and video calls inside the project.
  • Invite anyone. Guest links for clients — only the sheets you pick, no account needed.
  • Roles and history. Viewer, reviewer, editor, admin; named versions you can compare and restore.

AI and MCP

  • Bring your own model. Claude, GPT, Gemini or a local model (Ollama, LM Studio) with your own key — the AI panel works with all of them.
  • Real tools, not chat. The AI draws walls, rooms, roofs and furniture through the same documented Agent API you can script yourself.
  • Agent-ready. Every tool is published as a JSON-schema tool (EX3D.tools, EX3D.call), so a browser agent using MCP can drive EX3D today; a hosted MCP server is on the way.
  • From a sketch. A photo of a hand-drawn plan becomes a model: cleaned, traced, measured.
  • Proven. The Farnsworth House showcase was modelled entirely through the Agent API.

From the maker

I'm Pablo, an architect from Colombia. Taking a design from sketch to final plans meant a messy maze of software & licenses.

I built ex3d.com to fix this: one app for drafting, modelling, & rendering.
