Tunnel Viewports

The Viewport draws the tunnel with added features to allow you to review the design. You have various options to adjust the view in the Viewport.

• Home returns the view axis orientation and zooms back to the default position while trying to ensure all tunnel features are visible and the largest possible size in the viewport
• Magnifying Glass creates a small, zoomed-in window that can be moved using the mouse
• Zoom Window allows you to zoom into a specific region of the model that is drawn using the mouse by left-clicking, dragging and releasing
• Zoom allows you to zoom into a specific point of the model that is drawn using the mouse by left-clicking, dragging and releasing
• Pan allows you to move the view without rotating the model
• Rotate allows you to change the view angle of the model
• Zoom Fit adjusts the view to ensure all tunnel features are visible and the largest possible size in the viewport
• View Cube has options for easier adjustment of the model view

These options can be hide / show or repositioned in the Display – Toolbar section in the Toolbar located at the right side of the viewport.

There are various View options to change the Viewport layout:

• 2D View focuses on the profile which is the tunnel cross-section

• 3D View shows the entire tunnel to illustrate the location of all features
• Split View shows the 2D view at the top and 3D view at the bottom of the viewport
