What Space Designer 3D is
Space Designer 3D is browser-based software for drawing 2D floor plans, furnishing spaces, and viewing designs in real-time 3D. As you draw, room areas, wall lengths, and total floor surface update live. A library contains thousands of furniture items, fixtures, and decor, while a material editor lets you adjust finishes in real time. The service says it can generate HD and 8K photorealistic images from 2D floor plans. Drawing plans and modeling in 3D are always free, but renders and AI-enhanced images consume credits. Starter includes one project, a limited catalog, PNG, JPG, and PDF exports, and 10 rendering credits at no cost. Premium costs $25.00 per month; Ultimate costs $45.00 per month. Business plans and Enterprise add seats, accounts, integrations, APIs, custom catalogs, and infrastructure options. Exports listed include DXF, IFC, GLTF, PDF, and PNG. The product runs without installation.
