On the View menu, point to Camera, and then select from these settings.
Zoom to Fit
This option zooms in or out to allow all walls to appear within the view. It can also be actioned by double-clicking the middle mouse wheel, or by clicking "Fit All" on the View toolbar. This option can be used on 2D and 3D views.
Zoom to Area
First of all, select the option on the View menu, click a point on a 2D plan view and then draw out a rectangular selection box; hold down the left mouse button and drag the cursor to a second point on the screen and release the mouse button. The software then zooms in on the enclosed area. Similarly, zoom-to-area can be used on 3D views; click on the view to generate a rectangular area which is used to determine the zoom region. Drag the mouse cursor to resize the rectangular area.
Zoom to Selection
Use the Select tools to select a wall, window, shade, or space on a 2D plan view and then click "Zoom to Selection" to zoom in on the selected building component or construction type.
Zoom In
Zoom closer to the building - also available using the mouse wheel. This function alters the viewing location by moving it closer to the building, whilst the target position remains fixed.
Zoom Out
Zoom out from the building - also available using the mouse wheel. This function alters the viewing location by moving it further away from the building, whilst the target position remains fixed.
Tip: to move both the viewing location and target position, use the arrow keys on the keyboard. The arrow keys are used to simulate walking around the inside of the building. Tap the right-Shift key on your keyboard to increase movement but avoid holding down the button, as each tap of the key increases speed. And each tap of the Backspace key decreases it.
Pan
Moves the camera parallel to the current view plane in the horizontal and vertical direction; the camera is moved perpendicular to the direction in which it is pointed, where the direction itself is fixed. This option is available in 2D and 3D views and can be actioned also by holding down the mouse wheel.
Orbit
Moves the camera position around the building by rotating about the target point, allowing viewing from various vantage points. This option is enabled only for 3D views and disabled for 2D plan views. The orbiting tool is accessible also by moving the mouse while pressing the mouse wheel and holding down the Shift key.
Rotate Camera
Rotates the camera direction about its axis. This option is enabled only for 3D views and disabled for 2D plan views.
Setup view
Opens the "3D View Setup" dialog allowing you to enter an eye and target position.
Enable the "Enter Point" radio-button for the "Eye Position" on the dialog. Input the eye position in metres and then click Apply. Now enable the radio button for the "Target Position" and enter the height at which the target point should be fixed and click Apply. If the eye and target heights are the same then you are looking directly ahead, but if the target height is set higher or lower than the eye position then you are looking up or down, respectively.
Relocate the viewing location by selecting the Eye Position radio button and then clicking a point on the 2D floor plan using the left mouse button. Or click the "From sun direction" button to set the viewing location from the sun.
Enable the Target Position radio button and click a point on the 2D floor plan defining the direction in which the viewer is looking and the distance from viewing location.
Faster Interactive
Moving the camera around the building using the "Orbit" tool on the View toolbar or using the "Rotate camera" tool to point the camera in different directions can be sometimes slow if the geometry is particularly complex. This is true also when using the Pan tool. Enabling "Faster Interactive" quickens the process by seemingly removing windows and shades from the view and disabling the grid as the model or camera is rotated, repatriating them with the building after the mouse button is released.
