Pascal Editor

Pascal Editor is an open-source 3D building editor that lets users design, construct, and share home projects in the browser.

Pascal Editor is a free, open-source 3D architectural tool for designing walls, rooms, levels, roofs, furniture, and interior layouts directly in a web browser. Users can scan spaces, sketch new ideas that turn into solid geometry, and organize building projects on a single 3D canvas. The software features parametric SDF and CSG shapes, a library of ready-made 3D objects, and first-person walkthroughs. It is built for designers, developers, and creators who want to build and share interactive architectural projects. The platform includes an MCP server for AI agents, npm packages for embedding, and support for IFC models under an MIT license.
