Switch Projection Modes in the Viewer

Projection modes determine how 3D space is interpreted within the viewer. By switching modes, you can choose the view that best suits your current task—whether you need a realistic sense of depth for navigation or an undistorted view for verifying technical alignments.
Perspective (3D): This is the default mode. It mimics the human eye by making objects further away appear smaller. This provides spatial depth, making it ideal for first-person "fly" walkthroughs and general site orientation.
Orthographic (2D): This mode removes depth distortion. Every object maintains its true scale regardless of its distance from the camera. This is essential for verifying vertical alignments, checking clearances between systems, and producing elevation screenshots.

Example
See these examples to view the difference between projection modes.
Perspective Mode (Default)
Perspective mode mimics the human eye, making objects that are further away appear smaller. This creates a sense of depth that is ideal for "flying" through a site or orienting yourself within the 3D environment.
Orthographic Mode
Orthographic mode removes depth distortion so every object maintains its true scale, regardless of its distance from the camera. This is a helpful tool for checking if systems are vertically aligned or for capturing clear elevation views without the distortion of a vanishing point.
