Editor

Pascal Editor is a free, open source 3D building editor that runs in the browser. It lets people sketch or import a building and then work with walls, rooms, levels, roofs and furniture on a single 3D canvas, moving walls, swapping furniture and testing layouts, before presenting the result as a first person walkthrough others can explore. The audience is broad: homeowners planning a renovation, architects, contractors, property developers, game designers, content creators and digital twin companies. Around the editor sit Pascal Capture, an iOS app that scans a real space into 3D using parametric shapes that blend and carve, AI generation that turns strokes sketched onto the model into solid geometry, Pascal Studio for stylised renders with glass, iridescent and procedural materials, and an asset library of ready made objects. A community gallery shows shared projects. For developers, the viewer, editor and scene engine are published as npm packages under the MIT licence, an IFC converter imports existing building models, and an MCP server lets AI agents read and reshape scenes, including rooms, objects, materials and building systems. The editor itself is free to use. AI generation draws on AI credits and offers a choice of frontier models, but the site does not publish a pricing page or credit prices, so the cost of AI features is unpublished. Because the code is developed in the open, teams can embed the viewer or the full editor in their own product rather than relying only on the hosted app.
