Selection

Highlight

Sets the type of highlight applied when selecting objects. The result differs depending on the element you select.

When you select the whole part:

Standard applies a very basic highlight.
Glow applies a halo and a transparency effect. "Halo" is a neon effect that slightly illuminates the highlight.
Polite makes visible and hidden faces clearly visible.
Glow Polite is a mix of Glow and Polite. It applies a halo, a contour, and two transparency effects to make visible and hidden faces clearly visible.


Standard	Glow	Polite	Glow Polite

When you select a face:

Standard does not fully render the hidden face, and only its edges are visible.

Important: The highlight behavior is different in Visu mode and in Edit mode:

In Visu mode, only the face is highlighted.
In Edit mode, the face and its edges are highlighted.

To switch between the two modes, click Switch to Visu Mode or Switch to Edit Mode from the Tools section of the action bar. For more information, see Product Structure Design User's Guide.

Glow renders visible and hidden faces the same way with a halo and a transparency effect.
Polite renders hidden elements with a transparency effect.
Glow Polite renders visible and hidden faces with a halo and two different transparency effects for visible and hidden parts.


Standard	Glow	Polite	Glow Polite

When you select edges:

Standard renders edges with the color specified through the Selected edges option.
Glow renders edges with a halo effect. The Selected edges option has no impact.
Polite renders edges with an increased thickness, and hidden edges are transparent. The Selected edges option has no impact.
Glow Polite renders edges with a halo effect.

Important:

This option uses Multisample antialiasing (MSAA) but some artifacts might appear between edges and selected faces, and colors might be mixed.
Objects that are not in the Z-buffer are occluded.
When a corner's edge is selected, part of this edge might be hidden whereas the rest is visible.
Visualization parameters defined through the View Modes... command are not taken into account.

By default, this option is defined to Glow Polite.

Selected elements: Sets the color of selected elements.
Selected edges: Sets the color of selected edges.

Prehighlight

Specifies the type of prehighlight to apply when preselecting objects. The result differs depending on the element you select.

When you preselect faces and edges:

XOR renders the contour of the preselected face with a stipple pattern. The algorithm uses XOR binary operator to display prehighlighted elements: DisplayColor = (PrehighlightColor XOR CurrentColor).
Glow renders the contour of the preselected face, if visible.

Polite renders hidden edges with a transparency effect. This mode lets you identify more precisely the position of hidden and visible elements you preselect.

Important: The prehighlight behavior is different in Visu mode and in Edit mode:

In Visu mode, only the face is prehighlighted.
In Edit mode, the face and its edges are prehighlighted.

To switch between the two modes, click Switch to Visu Mode or Switch to Edit Mode from the Tools section of the action bar. For more information, see Product Structure Design User's Guide.

Glow Polite is similar to Glow. It renders the contour of the preselected face with an increased thickness.

In the examples below, the prehighlighted faces are those on top of the model and the inner face.

By default, this option is defined to Glow Polite.

command are not taken into account.

Preselected elements: Sets the color of preselected elements.
Preselected element linetype: Sets the linetype used to display preselected elements.

Selection

Preselect in geometry view

Activates preselection highlighting. As you point to objects, different parts of the objects are highlighted in the work area, and the object name is highlighted in the tree. However, deactivating this option impacts all commands using prehighlight, especially the Other Selection... command that does not work anymore.

Note: This option has no effect when a selection filter is applied for a specific type.

By default, this check box is selected.

Preselection navigator after ... second(s)

Sets the amount of time, in seconds, which elapses before the preselection navigator appears when pointing at an object.

By default, this check box is cleared.

Highlight in geometry view

Activates highlighting in the work area.

Note: This option has no effect when a selection filter is applied for a specific type.

Highlight faces and edges

Controls the way faces and edges are prehighlighted and highlighted.

Important: The highlight behavior is different in Visu mode and in Edit mode:

In Visu mode, only the face is highlighted.
In Edit mode, the face and its edges are highlighted.

To switch between the two modes, click Switch to Visu Mode or Switch to Edit Mode from the Tools section of the action bar. For more information, see Product Structure Design User's Guide.

The way elements are prehighlighted and highlighted varies according to the current visualization mode: Shading with Edges, Shading, Wireframe (NHR), Dynamic hidden line removal (HRD). Some minor differences in the way elements are highlighted are noticeable using the HRD mode.

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.

Warning: This option has no impact on bodies without edges: when you highlight the whole body, all its faces are highlighted, even if the Highlight faces and edges option is cleared. This does not apply to bodies whose edges are hidden.

By default, this check box is cleared.

Display manipulation bounding box

When clicking an object (either in the 3D area, or in the tree), displays a bounding box around the selected object if it uses handles.

The bounding box takes into account the assembly constraints of the object.

Objects using handles can be manipulated by the Robot.

By default, this check box is cleared.

Limit display of handles to ... element(s)

Specifies a limit on the number of elements in multiselection mode (using the selection trap) on which handles 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 also optimizes the selection when large amounts of elements are involved. The consequence is that the selection becomes faster but also less accurate. Therefore, when the limit is exceeded, some selected elements may not be highlighted and the handles may not be displayed, even though the number of selected elements is reduced afterward.

This option is selected when working in a 2D context (objects with handles such as texts and arrows, for example) or 3D context.

Important: Setting a high number (greater than 500) has an impact on the context menu that is not displayed anymore. To display the context menu, specify the limit to a higher number. If the number of selected elements is not higher than 500, the context menu is always displayed, even though the limit has been specified to a lower value.

By default, the limit is set to 50 elements.

Display immersive list for preselection navigator

Displays the list of all the elements you can preselect when using the preselection navigator. The immersive list displays all the stacked elements you can preselect.

This information is identical to the one displayed in the status bar.

Important: If Display auxiliary viewer for preselection navigator is cleared, you can use either the keyboard arrows, or the mouse to navigate in the immersive list. Otherwise, you can only use the mouse.

By default, this check box is selected.

Display auxiliary viewer for preselection navigator

Displays a viewer showing 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 navigator

Highlights the faces you preselect using the preselection navigator.

By default, this check box is cleared.

Display immersive viewer for preselection navigator

Displays the immersive viewer when using the preselection navigator. The immersive viewer provides visual feedback on the preselected element and lets you validate your selection.

This circle with an opaque background shows the preselected element and displays the surrounding elements in transparency.

A cross pinpoints the preselected location. Four arrows let you navigate or scroll through the object you point at. These arrows turn black when you reach an extremity.

This viewer keeps the proportions of the current viewer.

By default, this check box is selected.

Activate highlight of hidden objects

Highlights hidden objects you select.

You can select objects from the tree at representation or product level, or from any dialog box requiring a selection as an input.

Important:

This option has no effect if Highlight in geometry view is cleared.
This option has no effect when a selection filter is applied for a specific type.

By default, this check box is cleared.

Activate prehighlight of hidden objects

Highlights hidden objects you preselect.

Objects can be preselected from the tree at representation or product level, or from any dialog box requiring a selection as an input.

Important:

When preselecting at product level, some edges are not visible.
This option has no effect if Preselect in geometry view is cleared.
This option has no effect when a selection filter is applied for a specific type.

By default, this check box is cleared.
