Sweet Home 3D
Sweet Home 3D is a home interior planning tool for drawing floor plans, placing furniture and previewing spaces in two or three dimensions. This page covers project units, imports, furniture libraries and export checks.
What Sweet Home 3D provides
Sweet Home 3D helps turn a measured floor plan into a simple interior layout, with walls, doors, windows, furniture and a 3D preview. It is a planning aid rather than a structural engineering tool; dimensions, load-bearing changes, electrical work and construction decisions need qualified review.
Units and project assets
Set the project unit before drawing, keep a clean scale reference and label rooms consistently. Add furniture libraries in small batches and save the project with its library dependencies so a later move to another computer does not leave placeholder objects.

Sweet Home 3D floor plan and furniture guide
Measure a small room, set units, draw the boundary, place a few objects and compare the 3D preview before building a larger project.
Before you start
- Prepare reliable room measurements, door and window positions and a simple furniture list.
- Decide whether the project uses metric or imperial units and keep that choice consistent.
- Create a project folder that includes the design file and any custom library assets.
Installation steps
- 01
Install and set project units
Install the package, create a new project and set the unit system before entering dimensions or importing a plan.
- 02
Draw the measured boundary
Add walls, doors and windows from one reference measurement, then check room dimensions and alignment before placing furniture.
- 03
Place objects and preview
Add a small furniture set, adjust height and orientation, switch between plan and 3D views and save a named project version.
Quick start
- 01
Keep a scale reference
Add one known-length wall or object and compare it against the measured room before refining the layout.
- 02
Organize furniture libraries
Install only the libraries needed for the project, record their source and keep custom models in a separate assets folder.
- 03
Export a review image
Render a simple preview, check labels and dimensions, and export a copy for discussion without treating it as a construction drawing.
Usage tips
- A visually pleasing preview does not validate structural, electrical or fire-safety decisions.
- Save versioned project files before large imports or unit conversions.
- Use neutral filenames for shared images when the plan contains a private address or household information.
Troubleshooting and uninstall
Why does an imported plan have the wrong scale?
Compare a known measurement, confirm the import unit and resize or redraw against a single reference before placing furniture.
Why are custom furniture objects missing after moving the project?
Check the library path and package the project assets together, then reopen the file and replace only the objects that remain unresolved.
- Archive the project and assetsSave versioned project files, exported previews and custom furniture libraries in a separate backup location.
- Remove the applicationUninstall Sweet Home 3D through the operating system and clear application settings only after confirming that the project archive opens elsewhere.
Frequently asked questions
Is Sweet Home 3D a construction engineering tool?
It is intended for home layout and visualization. Structural, electrical, plumbing and code decisions require qualified review and separate documentation.
How can project scale be checked?
Keep one measured reference length in the project and compare imported plans or furniture dimensions against it before refining the layout.
Does the download require an extraction code?
The Quark entry does not require one; the four-character code for the Baidu entry is shown beside its download entry.
