Description
Sweet Home 3D is an easy to learn interior design application that helps you draw the plan of your house in 2D, arrange furniture on it and visit the results in 3D.
Sweet Home 3D is aimed at people who wants to design their interior quickly, whether they are moving or they just want to redesign their existing home or office.
You may :
• Draw walls and rooms of your home from scratch or upon the image of an existing plan, on one or more levels.
• Change the color or the texture of the walls, the floors and the ceilings, importing images of your own patterns if needed.
• Drag and drop doors, windows and furniture onto the plan from a catalog of 1205 objects organized by categories, in which you can import 3D models created by yourself or downloaded from the web.
• Customize the
size
, the orientation, the elevation, the colors and the textures of each piece of furniture.
• View the changes in the plan simultaneously in a 3D view, in which you can navigate either from an aerial view point, or from a virtual visitor view point.
• Create a photorealistic image of your arrangement depending on the time of the day and the light sources placed in the plan.
• Create a video from a virtual path in the 3D view.
• Annotate the plan with room areas, dimension lines, texts, arrows and a compass rose.
• Print the home plan and the 3D view or export them in files at PDF, PNG, JPEG, SVG, OBJ standard formats, to reuse designed homes in other software.

Editor-checked details
Recommended for homeowners and interior designers checking circulation, furniture scale, level relationships and basic lighting before renovation. Workflow: capture requirements/measured dimensions; import and calibrate the plan; set units, wall thickness and heights; build walls/openings first; place true-size furniture; inspect circulation and sightlines in visitor view; set date, sun and lights; issue a low-resolution review; render final quality after approval; export PDF/SVG/OBJ and schedules; archive .sh3d, assets, manifest and SHA-256. Compare Live Home 3D or Home Designer for richer residential design, and use dedicated BIM software for professional construction workflows.
Pros
- Synchronized 2D planning and 3D viewing make walls, rooms, levels and furniture approachable. It supports calibrated background plans, dimensions, furniture/texture libraries and imported models. Sun, lights, photos and video paths cover basic validation and presentation, while PDF, SVG, OBJ, PNG/JPEG exports aid handoff. It is open source, cross-platform, works on Intel and Apple silicon, and suits rapid comparisons for homes and small offices.
Cons
- It is not BIM, construction documentation or code-checking software: component semantics, clash detection, MEP, engineering calculations and collaborative version control are limited. Areas, clearances and dimensions still need professional review. High-quality lighting renders can be slow, while dense models and large textures consume memory. Third-party models vary in scale, axes, materials and licensing, and OBJ exports may need cleanup. Catalog size depends on the distribution; custom libraries and plug-ins must be archived separately.
Installation steps
- The site build of Sweet Home 3D 7.5.5 requires macOS 10.15 or later and a 64-bit processor, with Intel and Apple silicon support. Before upgrading, duplicate .sh3d homes and archive custom .sh3f furniture libraries, .sh3t textures, .sh3p plug-ins, background plans, models and texture files. Calibrate an imported plan with a known dimension, then confirm units, wall thickness, level heights and magnetism. Use a small two-level test to verify joined walls, door/window cut-outs, underground levels, the detached 3D window and aerial/visitor views. Preview camera, date/time, sun and lights at low quality before recording final render size/quality. Validate scale, materials and coordinates after PDF/SVG/OBJ export.
Uninstallation steps
- Before uninstalling, copy .sh3d homes and every linked asset into an independent archive. Export plan PDF/SVG, furniture CSV, OBJ with MTL/textures and key-view PNG files; keep path settings and the final movie for video work. Create a manifest covering version, units, levels, library dependencies, plug-ins and fonts, then calculate SHA-256 for source and deliverables. Reopen the copy offline and verify furniture, textures, levels and a representative render before removing the app, plug-ins and preferences.
Common errors and fixes
- Recalibrate a background plan from a known dimension rather than trusting scan DPI. Open rooms or wrong areas usually mean unsnapped wall endpoints, inconsistent thickness or incorrect level elevations. If a door/window does not cut a wall, confirm its imported type, elevation and depth. For black, flickering or crashing 3D views, update macOS, reduce antialiasing/render quality, remove the newest high-polygon model and compare with a blank home to separate GPU issues from file damage. Keep OBJ, MTL and textures at stable relative paths. Reduce texture size/polygon count for memory errors. Detached-view synchronisation and underground levels at equal elevations are key 7.5 regression checks.
What changed in this version
- The site release note for 7.5.5 states stability improvements and bug fixes. Verifiable 7.5-series fixes include 3D-view synchronisation in a detached window, rendering underground levels at the same elevation and Thai UI fonts. Wall drawing, furniture catalogs, photorealistic rendering, video paths and multi-format export are established features, not presented as new 7.5.5 additions.
