Gravitational effects during navigation

Fixes the X, Y, or Z axis during navigation. While turning in Fly mode, this creates the impression that your viewpoint tilts or banks with respect to the fixed axis, as in a real plane.

By default, this check box is cleared.

Follow ground at altitude (in mm)

First, select the Gravitational effects during navigation check box to be able to select this option. When flying and walking, this gravitational effect makes you automatically fall if you do not reach the specified altitute (in millimeters). This allows you to follow the ground relief, such as stairs.

An altitude set to 0 means that the eye level is set at ground level, whereas an altitude higher than 0 sets the eye level above ground level.

Note: The Follow ground at altitude check box is automatically cleared when no ground is selected because it is not relevant.

By default, this check box is cleared.

Animation during viewpoint modification

Set this option if you want viewpoint changes in certain contexts to be animated.

To see an example of the effect of this option, click the option, then select a plane and click Sketch. The selected plane is slowly rotated until parallel to the screen just like during an animation. If you do not select this check box, the selected plane is set parallel to the screen immediately without the animation effect.

Note: The visualization time of the product impacts the number of animation steps. The longer the duration, the fewer steps. In case the visualization takes too much time, there is no viewpoint animation at all.

By default, this option is selected.

Disable the rotation sphere display

Hides the rotation sphere usually displayed when rotating an object.

By default, this option is selected.

Fly/Walk

Show navigation icon: Lets you display the Walk or Fly target when navigating.
By default, this check box is selected.

Mouse-free navigation

Lets you fly or walk through objects without using the mouse, only the keyboard.

This is especially useful to select objects using the mouse, or when using Product Finder, for example.

By default, this check box is cleared.

Collision detection enabled

Select this check box to make collision detection options available. Then, activate a collision mode by selecting the appropriate option below.

By default, this check box is cleared.

Point/scene collision

When flying and walking, detects if you collide with an object, so that you bounce off the object instead of going through it. This is the default option.

By default, this check box is selected.

User-defined collision detection distance (in mm)

Similar to Point/scene collision, except that you can decide a distance at which it detects objects for collision, and slides according to navigation direction during walk or fly.

When flying and walking, the option detects if the sphere collides with an object, so that you bounce off the object. As no object can break through the sphere, this provides a more immersive experience.

Note: If you already are in the boundary defined in the Preferences, this option starts detecting collision from that point. For example, if you specify 1000 mm and start walking or flying at 100 mm from the object, collision detection starts at 100 mm from the object. If you move back more that 1000 mm away from the object, then it will consider 1000 mm for collision detection.

By default, this check box is cleared.

Start speed

When you start flying, this option lets you choose between two options:

Automatic: you start flying at the default speed. This means that the speed at which you first approach the object depends on the initial distance from the object, and is calculated automatically.
By default, this check box is selected.
Custom: you use the slider to define by yourself the speed at which you first approach the object.
By default, this check box is cleared.

Mouse Speed

Sets the time interval (from 0 to 100 milliseconds) during which mouse movements are not taken into account for prehighlight purposes. The higher the speed, the fewer elements are prehighlighted.

Angle value for keyboard rotations

Sets the angle value applied when rotating objects using the keyboard (such as pressing Shift and the up arrow to rotate the object about the X axis).

The default angle value used for keyboard rotations is 9 degrees. This means that to perform a rotation of 180 degrees, for example, you press 20 times the corresponding keyboard shortcut.

This option lets you choose the angle value when performing rotation operations. You can perform smaller or greater rotations by pressing a key combination only once. This also facilitates the navigation in the object by minimizing the number of interactions. To set the angle value, click the up or down arrow until you reach the appropriate value, or enter your value directly in the box. Available values range from 0 degrees (no rotation) to 360 degrees (full rotation about one axis).

By default, the angle value is set to 9 degrees.

Tight Reframe

Ensures use of maximum available space when viewing models using the Fit All In command.

This option is useful for large models because it is based on the model visualization, and not on the geometry that considers the bounding sphere.

By default, this check box is cleared.
