This tab deals with the following categories of options: | ||||||||||||
Selection |
||||||||||||
Preselect in geometry viewActivates preselection highlighting. As you point to objects, different
parts of the objects are highlighted in the geometry area, and the object
name is highlighted in the specification tree. By default, this option is activated. |
||||||||||||
Preselection navigator after ... second(s)Sets the amount of time, in seconds, which elapses before the preselection navigator appears after pointing at an object. Refer to Selecting Using the Preselection Navigator for more information about how to use the preselection navigator. By default, this option is cleared. |
||||||||||||
Highlight faces and edgesControls the way faces and edges are prehighlighted and highlighted. How elements are prehighlighted and highlighted:
The default prehighlight and highlight colors are different, and can be customized using the Visualization tab. By default, faces and edges are highlighted. Depending on the element type, elements may or may not be displayed using the Z-buffer. The following examples use the shading mode. When you are editing an object, a selected face is highlighted like this: |
||||||||||||
... and a selected edge is highlighted like this: | ||||||||||||
If you select the Pad or the PartBody in the specification tree, the whole object is highlighted like this: | ||||||||||||
If you are in
Visualization mode in an assembly, the whole object is highlighted. By default, this option is cleared. |
||||||||||||
Display manipulation bounding boxWhen clicking an object, displays a bounding box around the selected object if it uses manipulators: |
||||||||||||
Objects using manipulators can be manipulated by
the 3D compass. For more information about manipulating objects
using the 3D compass, refer to
Manipulating Objects Using
the Mouse and Compass. By default, this option is cleared. |
||||||||||||
Limit display of manipulators to ... element(s)Sets a limit on the number of elements selected in multi-selection mode (using the selection trap) on which manipulators can be displayed. In case you select more elements than the limit (for example, by
pressing Ctrl to extend the selection), no element can be
manipulated. This option is activated when working in a 2D context (objects with handles such as texts and arrows, for instance) or 3D context. The following scenario takes the Drafting application as an example: |
||||||||||||
1. Enter a value in
the Limit display of manipulators box, 10 for
instance then click OK to validate.Note that setting a high number (greater than 50 )
has an impact on the content of the contextual menu displayed when right-clicking a selected element: the contextual menu is reduced and therefore, do not display all the commands available. 2. In the geometry area, select six elements either using the selection trap or by pressing Ctrl. As you can see below, manipulators are displayed on the selected elements to let you modify them: |
||||||||||||
If you set the
limit to 5 instead of 10 , no manipulator is
displayed since the number of selected elements (i.e. six) exceeds the
limit: |
||||||||||||
Display immersive list for the preselection navigatorDisplays the list of all the elements you can preselect when using the
preselection
navigator. By default, this option is activated. |
||||||||||||
Display auxiliary viewer for preselection navigatorActivates an auxiliary viewer displaying the preselected object when using the preselection navigator. This viewer enables you to perform viewing operations with the mouse such as zoom, rotate or pan. By default, this option is cleared. |
||||||||||||
Prehighlight faces for preselection navigatorActivates the highlight of the faces you preselect using the preselection navigator. By default, this option is cleared. |
||||||||||||
Display immersive viewer for preselection navigatorActivates the display of the immersive viewer when using the preselection navigator. By default, this option is selected. |
||||||||||||
Navigation |
||||||||||||
Gravitational effects during navigationFixes the X, Y or Z axis during navigation. While turning in Fly mode, this creates the impression that the user viewpoint tilts or banks with respect to the fixed axis, as in a real plane. By default, this option is cleared. |
||||||||||||
Follow ground at altitude (in mm)First, select the Gravitational effects during navigation
check box to be able to activate this option. An altitude set to "0" means that the eye level is set at ground level, whereas an altitude higher than "0" will set the eye level above ground level. Note that the Follow ground at altitude check box is automatically cleared when it is not relevant, i.e. when no ground is detected. By default, this option is cleared. |
||||||||||||
Animation during viewpoint modificationSet 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 less steps. In case the visualization takes too much time, there is no viewpoint animation at all. By default, this option is activated. |
||||||||||||
Disable the rotation sphere displayHides the rotation sphere usually displayed when rotating an object. The result is as follows:
|
||||||||||||
By default, this option is cleared. | ||||||||||||
Fly/walk |
||||||||||||
Collision detection enabledSelect this check box to activate the following two options: |
||||||||||||
Point/scene collisionWhen 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 option is activated. |
||||||||||||
Sphere/scene collisionWorks the same way as Point/scene collision but this time, the user is modelized as a sphere whose radius can be defined by entering a value (in millimeters) in the box to the right. 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 that this detection collision mode works with complex geometry
since it is based on visualization triangles. However, bear in mind that there is a price to pay in performance when using large models. By default, this option is cleared. |
||||||||||||
Mouse SensitivitySets the mouse sensitivity when flying and walking: if you set a low value, pointing the cursor produces only slow, minor changes in direction; if you set a high value, pointing the cursor produces rapid, significant changes in direction. |
||||||||||||
Start SpeedWhen you begin to fly, this option lets you choose between two options:
|
||||||||||||
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 value of the angle applied when rotating objects using the keyboard (such as pressing Shift and the up arrow to rotate the object about the X axis). For more information on how to perform rotations using the keyboard, refer to Activating Viewing Tools. | ||||||||||||
The default
angle value used for keyboard rotations is 9 degrees. This means that until
now, if you wanted to perform a rotation of 180 degrees for instance, you
had to press 20 times the corresponding keyboard shortcut.
From V5R17 onwards, you have the ability to choose the angle value
to be applied when performing rotation operations. This lets you perform
smaller or greater rotations by pressing a key combination only once. This
also facilitates the navigation in the model by minimizing the number of
interactions. Below are two examples with Ctrl + Shift + right arrow keyboard shortcut enabling you to rotate about the Y axis: |

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