Pascal Editor

Pascal Editor is a powerful, open-source 3D building editor that runs directly in your web browser. It's designed for architects, facility managers, home services, and anyone who needs to create detailed 3D architectural models.

Built with modern web technologies like React Three Fiber and WebGPU, Pascal Editor provides a professional-grade 3D modeling experience without requiring any software installation. It features advanced visualization modes like exploded views, cut sections, and X-ray views, and integrates with AI agents through the Model Context Protocol (MCP) for enhanced workflows.

Pascal Editor is designed for a wide range of professionals including:

Architects - Create detailed architectural models and presentations
Facility Managers - Manage building systems and infrastructure with 3D documentation
Home Services - Plan and visualize home improvements, renovations, and interior design
Home Builders - Design and plan construction projects with precise 3D modeling
Urban Planners - Design and visualize urban spaces and infrastructure
AI Developers - Integrate AI agents with building design through MCP protocols

Getting started with Pascal Editor is easy:

Visit the web application to start using it directly in your browser
Create an account to save your projects and collaborate with others
Choose a template or start with a blank canvas
Familiarize yourself with the tools in the left panel for drawing walls, placing furniture, and creating zones
Use the visualization tools to explore your design from different perspectives

For a more powerful local experience, you can use the CLI to run Pascal Editor locally on your machine.

Pascal Editor includes a comprehensive set of features for professional 3D architectural design:

Advanced 3D Visualization - Exploded view, cut view, X-ray mode, and immersive walkthrough
Interactive Design Tools - Wall drawing, furniture placement, zone creation, and real-time material changes
AI Agent Integration - MCP protocol support for intelligent design assistance and automation
Professional Rendering - WebGPU accelerated graphics with real-time lighting and material editing
Collaboration Features - Real-time multi-user editing, project sharing, and version history
Data Management - Local-first architecture with automatic cloud backup and project templates

Pascal Editor is currently free to use during its development phase. We are committed to keeping the core editor open-source and accessible. As the platform evolves, we plan to offer tiered subscription plans for professional teams and organizations that need advanced collaboration features, additional storage, and premium AI integrations.

Data security is a top priority for Pascal Editor:

Local-First Architecture - Your projects are primarily stored locally in your browser, giving you control over your data
Secure Cloud Sync - When you choose to save projects to the cloud, all data is encrypted in transit and at rest
No Unnecessary Collection - We only collect the minimum data required to provide the service
Privacy-Focused - We don't use your design data to train AI models without your explicit permission
Regular Security Audits - Our systems undergo regular security reviews to protect user data

The CLI version stores data locally on your machine by default, with optional cloud backup available.

Model Context Protocol (MCP) is a standardized way for AI agents to interact with external tools and data sources. Pascal Editor provides MCP tools that allow AI agents to:

Read and modify building designs
Analyze spatial relationships and constraints
Generate design suggestions and documentation
Perform automated compliance checks

This integration enables powerful AI-assisted workflows where AI agents can understand your architectural context and provide intelligent assistance directly within the editor.

We offer several support options to help you get the most out of Pascal Editor:

Documentation - Comprehensive guides and tutorials available on our website
Community Forum - Connect with other users and share tips and tricks
Email Support - Reach out to our team for direct assistance
Video Tutorials - Visual guides for key features and workflows

Regular Updates - We continuously improve the editor based on user feedback

As an open-source project, we also welcome contributions and bug reports from the community.

The web-based version of Pascal Editor requires an internet connection to function. However, we offer a CLI version that can be run locally on your machine for offline use:

Install the CLI using Node.js 22.13 or newer: npm install --global @pascal-app/cli

Start the local editor: npx @pascal-app/editor

The editor will run locally in your browser without requiring internet access

The CLI version provides a persistent local installation and can also be used to connect AI agents through MCP for enhanced offline workflows.

Pascal Editor is designed to work with common architectural and 3D file formats:

Native Format - Projects are saved in Pascal's native format for maximum compatibility with editor features

IFC (Industry Foundation Classes) - Import and export BIM models in IFC format

3D Formats - Export models in OBJ, GLTF, and GLB formats for use in other 3D applications

Image Formats - Export 2D views and renderings as PNG or JPEG images

PDF - Generate PDF documentation and presentations of your designs

We continue to expand our format support based on user needs and industry standards.
