Pascal Editor

Install and use the 3D building editor on Windows or Mac with Bun and a local browser session. Pascal Editor is a web app, not a desktop installer. You install Bun, clone the repository, install dependencies, start the local dev server, and open the app in your browser at http://localhost:3000.

What You Need

Windows: Windows 10 version 1809 or later for Bun. Mac: macOS 13 or later for Bun. Both: Git, a terminal, and a browser. Recommended: Bun 1.3 or newer, because that is the setup documented in the repo.

Install Bun on Mac

STEP 1

Open Terminal and run the official install script.

curl -fsSL https://bun.com/install | bash

bun –version

git clone https://github.com/pascalorg/editor.git
cd editor

Install Bun on Windows

STEP 1

How To Use It

Core tools Select for choosing and moving objects. Wall for drawing walls. Zone for creating zones. Item for placing furniture and fixtures. Slab for creating floor slabs.

STEP 6

Build a simple scene

1. Pick a level or create one.
2. Use the wall tool to draw the room shape.
3. Add slabs, zones, and items.
4. Switch to Select mode to inspect or move objects.

STEP 7

Use undo and saved state The editor uses local state with undo and redo support. If you make a bad change, undo it from the app rather than rebuilding the scene.

STEP 8

Optional environment file

You do not need environment variables for the editor to work. Copy .env.example to .env only if you want address search. cp .env.example .env
