Sweet Home 7.5.7 on Mac

People who sketch floor plans for fun, or who need to rearrange a flat before moving furniture, tend to find Sweet Home 3D quickly. It is an interior design app that starts with 2D walls and rooms, then gives you a live 3D view from above or at eye level. You can edit every piece of furniture's size, orientation, height, colour and texture, and even record a video walkthrough of the result.

Before installing, a few things help. The app runs on macOS, Windows, Linux, iOS and Android, so it travels with you. On a Mac it needs OS X 10.9 or later, and it works on both ARM and 64-bit Intel machines. Exports go to PDF, PNG, JPEG, SVG and OBJ, which covers printing, sharing and further editing. The interface itself is available in twenty languages, including Russian, English, Spanish, German and French.

One thing people often ask about is the crack version. The official app is free for basic use, so a crack is rarely necessary. The main difference with the paid Pro version is extra features, but the standard build already handles multi-level plans and 3D video. If you are on a Mac, the install process is straightforward and the app runs without extra system tweaks.

Exports OBJ models to Blender, SketchUp, and Keynote

Sweet Home 3D plays nicely with the rest of your Mac. The OBJ export is the main bridge: you can bring a finished plan into Blender or SketchUp for more detailed rendering, or drop it into a Keynote presentation as a 3D object. The SVG export works well for diagrams you want to annotate in Affinity Designer or Illustrator before printing.

On the import side, the app accepts 3D models you have downloaded from sites like SketchUp's 3D Warehouse or made yourself in other tools. That matters when the built-in catalogue of 1,400 objects does not have the exact sofa or lamp you have in mind. Drag a model into the furniture library and it behaves like any other item.

macOS features like Quick Look work if you save the plan as a Sweet Home file. You can also use the standard Share menu to send a PDF or PNG straight to Mail, Messages or AirDrop. For larger projects, keeping the plan in iCloud Drive or Dropbox means you can open it on another machine without manual copying.

More approachable than Live Home 3D for casual projects

There are a few other interior design tools for macOS, and each has a different feel.

Live Home 3D is probably the closest competitor. It has a similar 2D-to-3D workflow and a large object catalogue. The main difference is that Live Home 3D puts more emphasis on photorealistic rendering out of the box, while Sweet Home 3D keeps the interface simpler and lighter on system resources. If you are on an older Mac or just want to sketch layouts quickly, Sweet Home 3D feels faster to get into.

Floorplanner runs mostly in a browser, though there is a macOS companion app. It is good for quick online sharing, but the offline capabilities are limited. Sweet Home 3D works fully offline once installed, which matters if you are working in a space without reliable internet.

SketchUp Free (the web version) is a different kind of tool. It is a general 3D modeller, not a dedicated home planner. You can build a house in it, but you have to place every wall and window manually from scratch. Sweet Home 3D gives you a specialised wall-drawing tool and a catalogue of ready-to-place doors, windows and furniture. For interior design specifically, it saves time.

Fixes walls that won't snap with grid snap enabled

Most issues people hit are easy to solve once you know where to look.

Walls not snapping together. If walls do not join properly at corners, check that you are using the wall creation tool with the grid snap enabled. Holding the Shift key while drawing forces straight lines at 45-degree increments, which helps align rooms neatly.

Furniture appears floating or sunk. This usually happens when a model's elevation is set wrong. Select the item and adjust the elevation value in the furniture table. Negative numbers lower it into the floor; positive numbers lift it above. For items placed on a different floor level, make sure you are editing the right level in the plan view.

3D view looks wrong or empty. The separate 3D view window sometimes desynchronises from the plan. Version 7.5 fixed this, but if it happens, close the 3D window and reopen it from the menu. The view should refresh to match the current plan state.

Can't find a specific object in the catalogue. Use the search field at the top of the furniture panel. The catalogue is organised by category, but search is faster. If the object still is not there, you can import a 3D model instead.
