Live Home 3D for Mac is a powerful and easy-to-use interior design and home planning software. It allows users to create detailed floor plans in 2D and 3D modes, perform interior decoration, and generate realistic visualizations. Whether professional designers are presenting concepts or ordinary users are planning home renovations, it provides an intuitive and efficient workflow.

I. Detailed Explanation of the Core Interface and Workspace

After launching the software, the main interface is divided into multiple functional areas that work together to complete design tasks.

Menu Bar and Toolbar: Located at the top of the window. It contains standard menus such as File operations, Edit, View, Object, and Tools. The toolbar below provides shortcut icons for commonly used tools, such as Select, Wall, Door, Window, Furniture, etc.
Project Browser (Left Panel): Usually located on the left side of the window. It contains two key tabs:
- “Project” Tab: Lists all floors, rooms, and all placed objects (walls, doors and windows, furniture, etc.) in the project in a tree structure, and is the core for managing and selecting elements.
- “Library” Panel: A built-in 3D model and material library with a massive amount of furniture, appliances, decor, building materials, and more, which can be dragged directly into your design.
2D Plan View (Main Workspace): The main area in the center of the window. By default, it displays the 2D floor plan of the current level, where you perform precise wall drawing, room division, and object layout. The view scale can be zoomed.
3D Real-Time View (Floating or Docked): It can exist as a floating window or docked alongside the 2D view. It renders the 3D scene in real time and supports navigation (walk, orbit, and fly modes). Any modification made in the 2D view is instantly reflected in the 3D view.
Inspector Panel (Right Sidebar): Located on the right side of the window. Its content changes dynamically based on the type of the currently selected object, and it is used to adjust precise parameters of the selected object, such as dimensions, position, rotation angle, material, color, and more.
Status Bar and View Controls: The bottom of the window displays information such as cursor coordinates and zoom ratio. The view control buttons in the corner allow you to quickly switch view layouts (e.g., 2D only, 2D and 3D side by side, 3D only).

II. Complete Workflow: From Project Creation to Export

1. Create or Open a Project

Create a New Project: After launching the software, click the menu bar File → New (shortcut Command + N). In the template selection window that pops up, you can choose “Blank Project” or start from a preset household template.

Open an existing project: Click the menu bar File → Open (shortcut Command + O), navigate to your project file (.livehome3d format) and open it.

2. Draw the building shell and interior walls

Steps:

Click the “Wall” tool in the toolbar (the icon is a section of wall).
In the 2D plan view, click to set the starting point, move the mouse and click again to draw a straight wall segment. You can draw continuously, and when closed it forms a room. Press the Esc key to finish drawing.
In the inspector panel, you can adjust the thickness, height, baseline and other properties of the selected wall.
Use the “Room” tool to quickly draw a rectangular room, and the software will automatically generate four walls.

Tips: While drawing, pay attention to the length and angle prompts in the status bar. Hold the Shift key to lock to horizontal, vertical, or 45-degree directions.

3. Add doors and windows

Steps:

Select the “Door” or “Window” tool in the toolbar.
In the “Library” tab on the left, expand the “Door” or “Window” category and choose your preferred style.
Drag the selected door or window model onto a wall in the 2D view. When the cursor approaches the wall and a highlight appears, release it, and the software will automatically embed it into the wall.
Select a placed door or window, and in the Inspector panel on the right, you can precisely adjust its width, height, elevation above the floor, position on the wall, and opening direction.

4. Furnishing and Decorating

Steps:

In the “Library” tab on the left, browse or search for furniture categories (such as living room, bedroom, kitchen, etc.).
Drag the item you like directly to the appropriate position in the 2D or 3D view.
In the 2D view, use the Selection tool (shortcut V) to select an object, then:
- Move: drag the object itself.
- Rotate: drag the rotation handle on the object, or hold down the Command key and drag. Enter an angle value in the Inspector for greater precision.
- Scale: drag the corner handles, or adjust the dimensions in the Inspector. Hold down the Shift key to scale proportionally.

5. Applying Materials and Colors

Steps:

In the 2D or 3D view, double-click the surface of the object you want to modify (such as the floor, wall, or furniture panel).
The Inspector panel on the right will display the “Material” option. Click the material preview box to bring up the material library.
Select materials such as flooring, paint, tile, wood, etc. from the library and click to apply. You can adjust the scale and orientation of the material.
For simple colors, you can select the “Color” category in the material library, or use the color picker directly.

6. Navigation and Viewing 3D Effects

In the 3D view:

Orbit: Hold the left mouse button (or one finger on the trackpad) and drag.
Pan: Hold the right mouse button (or two fingers on the trackpad) and drag.
Zoom: Use the mouse scroll wheel, or pinch with two fingers on the trackpad.
Walk mode: Click the “Walk” icon (a small figure) on the 3D view toolbar to freely move through the scene using the W, A, S, D keys or the arrow keys, just like in a first-person game.

7. Exporting and Sharing Results

Steps:

Click the menu bar File → Export.
Choose the export format:
- Image: Export a high-resolution rendered image of the current view (PNG, JPEG).
- Video: Create a 3D walkthrough video (MP4, MOV); you need to record the walkthrough path in the 3D view first.
- PDF: Export a 2D floor plan with dimension annotations.
- 3D Model: Export to universal 3D formats such as OBJ and FBX for use in other software.
In the export settings dialog, adjust parameters such as resolution and quality, then click “Export” and choose a save location.

III. Advanced Tips for Common Features

Create multi-story buildings: At the bottom of the “Project” panel on the left, click the “+” sign to add a new floor. You can duplicate floor layouts and connect floors with the “Stairs” tool.
Precise dimension input: When drawing or moving objects, after a mouse operation, directly enter a numerical value via the keyboard (e.g., “3000” means 3000 mm), then press the Enter key to confirm, achieving precise positioning.
Object alignment and snapping: In the menu bar Live Home 3D → Preferences → Editing, enable “Smart Guides” and “Object Snapping.” When moving objects, they will automatically align to the edges or centers of other objects.
Custom materials: At the bottom of the material library, click the “+” sign to import your own images (such as wood grain or fabric patterns) from your computer as custom materials.
Create section views: In the 3D view toolbar, click the “Section” tool (scissors icon) to drag the section plane and view the interior cross-sectional structure of the house in real time.

IV. Common Problems and Solutions

Problem	Possible Cause	Solution
Unable to place doors or windows on walls	The drop position is not precisely aligned with the wall; the wall thickness may be 0.	Make sure the wall is highlighted when dropping. Check whether the thickness in the wall properties is a valid value (e.g., 120 mm).
3D view stutters or renders slowly	The scene is too complex (too many model polygons); high-quality rendering effects are enabled.	In the “Render Quality” drop-down menu of the 3D view, select “Standard” or “Draft.” Simplify the scene and temporarily hide unnecessary furniture.
Objects cannot be selected or moved	The object is on a locked layer or within a group; the current tool is not the selection tool.	Press the `V` key to switch to the selection tool. In the “Project” panel, check whether the object is locked (lock icon) or inside a group; you need to unlock or ungroup it.
Dimension annotations do not display or are incorrect	The annotation feature is not enabled; annotations are obscured by other objects.	In the menu bar `View → Show Plan Settings`, make sure the “Dimensions” option is checked. In the 2D view, adjust the position of dimension lines so they are clearly visible.
Imported materials appear too bright or too dark	The reflectivity or brightness parameters of the custom material do not match.	After applying the material, in the “Materials” section of the inspector panel, adjust the “Glossiness” and “Brightness” sliders until you achieve the desired effect in the 3D view.
