Navigate

You can view the model both internally and externally by flying in the model. Select View | Projection | Isometric Navigate.

During flying, the model is viewed in a perspective projection. The movement is affected by the movement step turning speed and view angle variables, the values of which are displayed in a prompt in the status bar. You can use keyboard commands to change the values of these variables. You can control the movement either with the mouse or the keyboard.

When you are using the mouse to control the movement, the cursor will indicate the movement direction. The model moves smoothly and accurately, but the speed increases when moving towards the edges of the window. The speed is affected by the movement of the mouse, not the computer's performance. Movement speed is displayed as mm/s and turning speed as deg/s. The three mouse buttons are used when viewing the model: the left, middle and right mouse button. Move the mouse down (towards yourself), up (away from yourself), left or right.

The mouse control functions are:

• Left mouse button - When you move the mouse downwards, the model moves away from you. When you move the mouse up, you will move closer to the model. Other options are moving to left and right.
• Middle mouse button - Move the mouse upwards or downwards. The model will orbit around you.
• Right mouse button - Move the mouse upwards, downwards, left or right. You will orbit around the model.

When you control movement with the keyboard, you must type the variables controlling the navigation. The keyboard control functions are:

• Space - Return to the initial position.
• Backspace - Returns the viewing direction to the horizontal and the height position to the default value.
• F5 - Step forward at default height.
• F6 - Step back at default height.
• F7 - Step left at default height.
• F8 - Step right at default height.
• Up arrow - Step forward in the viewing direction.
• Down arrow - Step back in the viewing direction.
• Left arrow - Step to the left.
• Right arrow - Step to the right.
• Page Up - Step in the direction of the positive Z axis.
• Page Down - Step in the direction of the negative Z axis.
• Shift + Up arrow - Look up.
• Shift + Down arrow - Look down.
• Shift + Left arrow - Look left.
• Shift + Right arrow - Look right.
• Ctrl + Up arrow - Increase the field of vision by one degree.
• Ctrl + Down arrow - Decrease the field of vision by one degree.
• 1 ,2 ,3 ,4 ,5 ,6, 7 ,8 or 9 - Set the movement step: 1, 4, 15, 60, 250, 1000, 4000, 16000, 60000 mm.
• Q, W, E, R, T, Y or U - Set the Rotation step: 0.2, 0.5, 1.0, 2.0, 4.0, 8.0, 16.0 degrees.
• G - Sets gravitation on/off. When gravitation is on, the eye level tries to stay at a default height (1500 mm) from a surface below.
• B - Sets background image movement on/off.
• Esc - Stops flying.
