Flying in a Model
You can view the model both internally and externally by flying
in the model. Select Projection > Fly from the menu
bar.
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. The 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 button, the middle button and the
right 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 down, you will move
farther from the model. 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 up or down. The model will
orbit around you.
- Right mouse button - Move the mouse up, down, 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 - Restores the original position.
- Backspace - Restores the viewing direction to horizontal and
the height position to default.
- F5 - Step forward at constant height.
- F6 - Step back at constant height.
- F7 - Step left at constant height.
- F8 - Step right at constant height.
- Arrow up - Step forward in the viewing direction.
- Arrow down - Step back in the viewing direction.
- Arrow left - Step left.
- Arrow right - Step right.
- Page Up - Step in the +z axis direction.
- Page Down - Step in the -z axis direction.
- Shift + Arrow up - Viewing direction up.
- Shift + Arrow down - Viewing direction down.
- Shift + Arrow left - Viewing direction left.
- Shift + Arrow right - Viewing direction right.
- Ctrl + Arrow up - Increases the viewing angle by one
degree.
- Ctrl + Arrow down - Decreases the viewing angle 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 turning step: 0.2, 0.5, 1.0,
2.0, 4.0, 8.0, 16.0 degrees.
- G - Sets the gravitation on/off. When the gravitation is on,
the eye point tries to remain at a constant height (1500 mm) from
the below surface.
- B - Sets moving the background image on/off.
- Esc - Stops flying.
Note
- Stop the navigation by pressing the Esc key.
- If the model disappears from the work window in the middle of
