Learn 3D interior designs: Become Master in 3D design

Download and install Sweet Home 3D, the open source interior design software available for Windows, Mac, and Linux, with online access and free and paid versions.

Explore the four-window user interface of a 3d interior design tool, including 2d plan, 3d view, furniture catalog, and 2d sections, with drag-and-drop and live 2d–3d synchronization.

Open a new home project in the 3d interior design software, configure language, units, and currency, and set catalogs, navigation, and rendering preferences for accurate wall, floor, and pattern details.

Import a background image, align it to the plan by selecting the matching line, set the scale and origin, and finalize the imported plan.

Draw walls from the blueprint using the wall icon, starting at a corner and dragging to the opposite end. Adjust wall dimensions and outline interior walls to match the plan.

Learn to create a curved wall as a separate wall, set its center point, and adjust the angle to shape a custom interior feature in 3d design.

Edit walls by selecting them, modify starting and end points, adjust wall height and thickness, and apply colors or textures from the palette for 2D and 3D plans.

Drag doors and windows from the furniture catalog and windows palette into the plan, resize and adjust height, then customize color, texture, and materials in the 3D view.

Learn to add furniture in 3D interior design, placing living room, dining, bedroom, and kitchen items with drag-and-drop, rotation, scale, and elevation adjustments for realistic layouts.

Learn to draw rooms in a 3d interior design plan using the add room tool, create bedrooms, living and dining areas, and customize floors and textures.

Add and manage levels in a 3d interior design project by creating ground and first-floor levels, adjusting height and floor thickness, and placing spiral stairs between levels.

Master navigating and editing the 3D interior view, switching between aerial and top views, adjusting camera height and angles, and refining textures, lighting, transparency, and background blueprints.

Learn to draw the diamond dimensions in 3d interior design using the diamond icon from the pool palette, clicking corners to add and extend dimension chains in a CAD-like workflow.

Add and configure text on 3d plants using the add text tool, then adjust alignment, font, size, color, and visibility in 2d and 3d views, including elevation.
