1. Viewing a Model

You can navigate the exterior and interior of a model using either of two modes.

3D Overview Mode

When a model is opened, its 3D Overview is active and the View menu is open on the left.

  • To navigate using a mouse, use the scroll wheel to pan and zoom, and click and drag to rotate around the model.
  • Standard trackpad gestures can be used to zoom in and out as well as pan and rotate around the model.
  • To reset the initial Overview camera position, click or tap the Restore icon.

Room View Mode with Chief Architect® Sojourn®

Click or tap the Room View icon to enable additional options for navigating the model's interior using  Chief Architect® Sojourn®.

High Definition/Low Definition

3D Viewer has two Render Quality modes: High and Low Definition. Low Definition is the default mode and represents materials on object surfaces using solid colors. High Definition mode displays photo-realistic textures such as wood grain on object surfaces as well as image objects like plants, but requires more resources on your device.

You can switch between High and Low Definition in the View menu. Depending on the size of the model and the available memory on your device, the app may need to switch back to Low Definition mode automatically.

For added realism, Shadows can be toggled on in both LD and HD quality modes in Settings , under View.

The Anti-Aliasing option improves the appearance of angled edge lines, but can be toggled off to improve 3D Viewer's performance in Settings , under View.
