On the Navigation tab there are tools for navigation, using them you can view the current layout in 3D.

 

Using the 3D interface, you can consider in detail the features of placing cameras, "visit" in the premises of the 3D model-building, "walk" on the floors, etc.

Functions of mouse buttons

 

On the left mouse button the Orbit  is assigned - moving  the mouse cursor with the left button pressed rotates the 3D model in the space (or rotates the virtual viewer around the 3D model);

 

Function of the left button can be changed.

You can lock the rotation in vertical planes , leaving only the horizontal rotation , by checking the Lock>Vert. orbit checkbox .

 

On the middle mouse button the Move is assigned - moving 3D model in the field of view plane;

 

On the rotation of the mouse wheel the Zoom tool is assigned - wheel rotation zooms in or out the point in the 3D space, where the mouse cursor is.

 

Pressed Ctrl reduces step of zooming;

Step and direction of zooming by turning the mouse wheel can be changed widely using Navigation>Scale factor in the Options box .

 

On the right mouse button the Look around Look around  is assigned  - rotates the sight direction standing the virtual viewer stationary.

 

Layout size

 

Sizes of the whole layout on the screen in the format X:Y:Height.

 

3D navigation buttons

 

By these buttons you can change function of the left mouse button.

 

Orbit - moving  the mouse cursor with the left button pressed rotates the 3D model in the space (or rotates the virtual viewer around the 3D model).

This is default function of the left mouse button.

You can lock the rotation in vertical planes , leaving only the horizontal rotation , by checking the Lock>Vert. orbit checkbox

 

Move - moving 3D model in the field of view plane.

This is default function of the left middle mouse button. The middle mouse button works like in the Graphics window.

 

Zoom - moving the mouse cursor along vertical zooms in or out the point in the 3D space at the center of the display area. By double clicking in the display area you can specify a new center point.

Wheel rotation zooms in or out the point in the 3D space, where the mouse cursor is. The Zoom tool works like in the Graphics window.

 

Pressed Ctrl reduces step of zooming;

Step and direction of zooming by turning the mouse wheel can be changed widely using Navigation>Scale factor in the Options box .

 

Look around -  rotates the sight direction standing the virtual viewer stationary.

This is default function of the right mouse button.

 

Walk - controls movement of the virtual viewer in virtual horizontal plane. Pressing the left mouse button fixes the starting point, moving the cursor from the starting point with left mouse button pressed sets the direction and speed of movement.

 

Zoom frame . Pressing the left mouse button specifies the first point of the zoom frame,  moving the cursor with left mouse button pressed and releasing the left mouse button generates the ZOOM frame. After releasing the mouse button the virtual viewer will approach to content of the frame.

 

This tool works like the function of the right mouse button in the Graphics window.

 

Fixed views buttons

 

Allow to quick look at the model from any of 6 sides:Front view,Left view,Right view,Back view,Top view,Bottom view.

 

Lock panel

 

On the panel there are checkboxes, which can fix some of parameters that can be useful when navigating in the 3D space.

 

Height of viewer - fix the height above the ground of the virtual viewer;

Viewer tilt - fix tilt of the sight direction of the virtual viewer;

Vert. orbit - disable rotation in vertical planes by the Orbit , leaving only the horizontal rotation.

 

Step backward and Step forward buttons

 

Allows to move on the chain of previous views backward and forward.

 

Sight direction of the virtual viewer

 

Sight direction of the virtual viewer in vertical and horizontal planes and its view angle are represented as a camera. The blue digits display the height of the virtual viewer above the ground.

 

View angle of virtual viewer slider

 

The slider allows to change view angles of the virtual viewer. Vertical angle value is displayed on the caption of the window.
