3D Viewer Preferences

1 min read

With the 3D Viewer Preferences dialog, an end user can configure the following preferences for viewing:

  • Projection: a 3D model projection mode.
  • Zoom to: an alignment points for zooming with a wheel mouse button.

These configurations are persistent for a given Viewer and logged-in user. An end user can have different configurations for the Monolithic and Dynamic/Streaming Viewers.

The Preferences button on the Standard Viewing toolbar provides access to the 3D Viewer Preferences dialog.

Projection Preferences

The Projection preference in the 3D Viewer Preferences dialog offers the following options for projecting a 3D model on a scene:

Orthographic: to show all objects on a 3D scene at the same scale regardless of their distance to a user. The farthest and nearest objects have the same size. This setting is default and reflects the legacy orthographic view projection behavior.

Perspective to show the following:

  • To show all objects on a 3D scene at different scales correspondingly to their distance to a user. The farther objects have smaller sizes than the nearer ones.

  • To zoom through a model. A user can view the model from the inside.

Zoom Preferences

The Zoom preference in the 3D Viewer Preferences dialog offers the following options for zooming with a wheel mouse button:

  • Viewport Center: to zoom in and out along the 3D scene viewpoint center regardless of the current cursor position. This setting is the default and reflects the legacy zooming behavior.
  • Cursor Position: to zoom in and out along the current cursor position.

These settings do not change the behavior of the Zoom Up and Zoom Down buttons on the Basic Viewing and Standard Viewing toolbars to zoom in and out along the 3D scene viewpoint center.
