Viewing & Sharing Models

3D Viewer models are exported from your Chief Architect or Home Designer desktop software and saved in your Chief Architect cloud account. You can include saved cameras to highlight particular details of the model, from color schemes in the living room to cabinet layout in the kitchen. From your Chief Architect cloud account you can then view, share, or even embed the 3D Viewer model on a web page. For more information about exporting, sharing, and embedding your models, please see our 3D Viewer support articles: for Chief Architect | for Home Designer.

Augmented Reality (AR)

With the Augmented Reality mode, you can place your 3D model in the real world and explore in detail by rotating, zooming or walking around. To view a 3D model in AR, use any horizontal surface such as a table, countertop or floor, then tap to place it when the AR surface grid appears.

Sojourn® 3D Virtual Reality Navigation Controls — Available in the Mobile App

  • Thumbsticks to move (fly) and rotate
  • Gyro camera for free-form viewing
  • Background camera on/off
  • Walk-Thru — allowing you to physically walk through the model
  • Dynamic camera height while in fly mode
  • Manual camera height adjustment

At the bottom of the screen, you will find controls for Overview and Room mode. When you are in the Room mode, the Sojourn® controls are available. There are also controls for High Definition (HD) and Low Definition (LD) mode. The LD mode does not display textures and uses less memory which may help to view home designs with high surface counts or on older mobile devices.

Navigation tools 3D Viewer

Cross-Section Slider

Use the Cross-Section Slider with six different cutting planes to view all angles and aspects of the home design. In the settings panel, there are controls for displaying a mini-map, aiding in the navigation of large models, defining your step length for the Sojourn® Walk-Thru mode, and using a game controller for navigation.
