Live Interior 3D Pro is a powerful and intuitive interior design and 3D modeling software built specifically for macOS. It allows users to create detailed floor plans from scratch and, on that basis, build realistic 3D models for virtual walkthroughs and high-quality rendering. This article aims to provide a detailed breakdown of the software interface and an operational workflow guide to help users quickly master its core features.

I. Detailed Overview of the Software’s Core Interface and Workspace

After launching the software, you will see a highly integrated workspace with a clear layout, mainly divided into the following key areas:

• Menu Bar and Toolbar: Located at the top of the window. The menu bar contains all software commands, while the toolbar provides quick-access buttons for the most 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 lists all elements of the project in a tree structure, including floors, rooms, walls, furniture, lights, cameras, etc. You can quickly select, hide, lock, or rename any object here.
• 2D Plan View (Main Workspace): The primary area in the center of the window. By default, it displays the two-dimensional floor plan of the current level and is the core area for drawing walls, placing furniture, and making precise dimensional adjustments. There are tabs at the top of the view for switching between different levels.
• 3D View (Main Workspace): You can switch to the real-time 3D preview window by clicking the “3D” tab above the 2D view or using the shortcut Cmd + 3. Here you can view your design from perspective or orthographic angles and perform real-time virtual walkthroughs.
• Inspector Panel (Right Sidebar): Located on the right side of the window. This is one of the most important interaction areas in the software. Its content changes dynamically based on the currently selected object type (such as walls, furniture, materials, lighting) and is used to adjust all properties of the object, including dimensions, position, rotation, material, color, and more.
• Library Browser (Bottom or Side Panel): Usually docked at the bottom or can be called up. It contains a massive library of preset models, such as furniture, appliances, decorations, door and window styles, material textures, etc., and supports categorized browsing and search. It is the resource center for enriching your design content.
• Status Bar and Information Prompts: Located at the bottom of the window, displaying current operation prompts, cursor coordinates, zoom ratio, and other information.

II. Complete Workflow from Creation to Export

1. Create or Open a Project

Step 1: Launch the software. A project wizard will automatically pop up. You can choose:

• Create a New Project: Start from a blank project, or use “Start from Template” to quickly select predefined room layouts (such as apartments, villas, etc.).
• Open an Existing Project: Via the menu bar “File” > “Open” or the shortcut Cmd + O, open a saved .live3d project file.

2. Draw the Building Structure

Step 2: Draw walls in the 2D plan view.

1. Click the “Wall” tool in the toolbar, or press the shortcut W.
2. Click in the 2D view to set the starting point, move the mouse, and click again to set the endpoint. While drawing, pay attention to the length and angle indicators in the status bar.
3. Draw a closed area to form a room. The software will automatically detect the enclosed space and fill in the room area.
4. Select any wall and precisely modify its length, thickness, height, and other parameters in the Inspector panel on the right.

Step 3: Add doors and windows.

1. Click the “Door” or “Window” tool in the toolbar, or use the shortcut D (door) / G (window).
2. From the Library Browser at the bottom, select your preferred door/window style and drag it directly onto a wall in the 2D view. The software will automatically create an opening in the wall.
3. Select the door or window and adjust its precise position (distance from the wall corner), dimensions, and opening direction in the Inspector panel.

3. Furnishing the Interior

Step 4: Add furniture and decorations.

1. Open the Library Browser at the bottom and browse or search by category (e.g., living room furniture, kitchen appliances, lighting, etc.).
2. Drag and drop the selected model directly to the desired position in the 2D floor plan or 3D view.
3. Select a placed object in the 2D or 3D view and use:
   • Move: Drag the object, or press the V key and use the mouse. Enter coordinates in the Inspector for precise positioning.
   • Rotate: Drag the object’s rotation handle, or press the R key and use the mouse. Enter an angle in the Inspector.
   • Scale: Drag the scale handle, or enter a ratio in the Inspector. Note that some models may only support uniform scaling.

4. Apply Materials and Lighting

Step 5: Beautify surfaces.

1. In the 2D or 3D view, click on the surface you want to modify (e.g., floor, wall, furniture surface).
2. In the Inspector panel on the right, locate the “Material” or “Appearance” tab.
3. Choose from the built-in material library (such as wood flooring, ceramic tiles, paint colors), or click the “+” button to import custom texture images and adjust their scale (UV mapping).

Step 6: Set up lighting.

1. From the “Lights” category in the Library Browser, drag light source models such as pendant lights and table lamps into the scene.
2. Add ambient light: In the menu bar, select “Edit” > “Add Object” > “Light” to add point lights, spotlights, or directional lights.
3. Select any light source and adjust its brightness, color, falloff range, and shadow properties in the Inspector panel.

5. 3D Preview and Walkthrough

Step 7: Switch to the 3D view for the experience. Click the “3D” tab above the 2D view or press Cmd + 3.

• Navigation controls:
  • Hold the right mouse button (or two fingers on the trackpad) and drag: rotate the view.
  • Hold the middle mouse button (or Option + left mouse button) and drag: pan the view.
  • Scroll the mouse wheel (or slide two fingers on the trackpad): zoom the view.
• Virtual walkthrough mode: Click the “Walk” or “Fly” mode button in the upper-left corner of the 3D view to freely move through the scene using the keyboard (W/A/S/D or arrow keys), just like a first-person experience in a game.

6. Render and Export the Final Result

Step 8: Create high-quality still images.

1. Adjust the ideal composition angle in the 3D view.
2. From the menu bar, select “Document” > “Render”, or click the Render button in the toolbar.
3. In the render settings window, choose the output quality (such as Preview, Standard, High), resolution, and whether to include shadows and reflections.
4. Click the “Render” button to start generating the image. Once complete, you can save it as PNG, JPEG, or TIFF format.

Step 9: Export an interactive presentation or a flat drawing.

• Export a 3D interactive presentation: Use “File” > “Export” > “Export as 3D Viewer Project” to generate a standalone file that can be viewed in a dedicated viewer.
• Export a 2D drawing: In the 2D view, use “File” > “Export” > “Export as PDF/Image” to output a flat layout drawing with dimension annotations.
• Save the project: Use Cmd + S at any time to save your .live3d source file for future edits.

III. Advanced Tips for Common Features

• Quickly duplicate objects: After selecting an object, hold the Option key and drag to quickly create a copy.
• Alignment and snapping: When drawing or moving, hold the Shift key to enable forced horizontal/vertical or angle snapping. In the “View” menu, you can enable “Smart Guides” to assist with alignment.
• Multi-story building design: In the Project Browser, right-click “Stories” and select “Add New Story.” You can connect different stories using stair objects and switch between them for editing in the tabs of the 2D view.
• Custom material library: Drag commonly used JPEG or PNG texture images directly into the material preview area of the Inspector to create and save custom materials for easy reuse.
• Camera view pinning: After adjusting to a specific angle in the 3D view, you can save that view via “Edit” > “Add Object” > “Camera,” and later switch back to this camera view at any time in the Project Browser.
