View Configuration Panel (PCB)

The Layers section of the panel's Layers and Colors tab

• Signal and Plane Layers – click the color button to change that layer's color, as described previously in the Displaying or Hiding a Layer section. Click the visibility icon () to toggle the display of an individual signal or plane layer. Signal and Plane layers are added, named, and removed in the Pad-Via Layer Editor dialog.
• Component Layer Pairs – these layers are paired so that when a component is flipped from the top side to the bottom side of the board (L shortcut as a component is being moved), the software can flip the top side layer contents onto their paired bottom side layers. User-defined component layer pairs can be defined using Mechanical layers.
• Mechanical Layers – these are general purpose drawing layers. These layers can also be paired and when paired, they become a Component Layer Pair. Component Layer Pairs are used for special-purpose roles, for example, glue dots, or 3D component bodies. To rename a mechanical layer, right-click on it to open the Edit Layer dialog from the context menu.
• Other Layers – these are system managed layers, for example, objects placed on the multi-layer automatically appear on all signal layers, and objects placed on the keepout layer act as a keep-clear boundary on all signal layers.
• Layers Sets – use the drop-down to select an existing Layer Set. The following buttons are used to create, save, and delete Layer Sets:
  • – click to create a new Layer Set. The set will appear as My Layers in the drop-down. Each subsequent Layer Set added will be numbered.
  • – click to save when you create a new Layer Set or if you have edited the currently selected Layer Set. The creating and renaming of a Layer Set do not require a save action, as those functions save automatically. Changing the configuration of enabled layers, including your own Layer Set, does require a save action.
  • – click to delete the currently selected Layer Set.
• Active Layers – use the drop-down to view one of the various Active Layers on the PCB individually.
• View From Bottom Side – check this box to view the Layer Sets from the bottom side.

• Import – click to import the desired PCB Layer Set File (*.layerset).
• Export – click to export the desired Layer Set as a PCB Layer Set File (*.layerset).

The System Colors section of the panel's Layers and Colors tab

• System Colors – use these controls to configure the color and visibility of special system display features, such as pad holes, the origin marker and DRC errors.

The General Settings change between 2D and 3D modes; hover the mouse to show the differences.

• Configuration – a configuration is a pre-packed definition of layer color and layer visibility settings. Select an existing configuration from the drop-down or use the buttons to create, save, or delete a configuration. Custom configurations save both of the current/last used 2D and 3D display settings.
  • – click to create a new Custom Configuration then type in a new name and click the button.
  • – click to save when you create a new Custom Configuration or if have edited the currently selected Custom Configuration.
  • – click to delete the currently selected Custom Configuration.
  Custom Configurations that have been created and saved are automatically loaded and available for selection from the Configuration field's drop-down listing.
• 3D – use the buttons to switch between the 2D layout mode and the 3D layout mode. Alternatively, press the 2 or 3 shortcut keys or use the commands in the View menu. Additional options will appear in 3D mode and are described below.
• Single Layer Mode – the design space display can be cycled through the Single Layer Modes at any time by pressing the Shift+S shortcut. This will leave the active or current layer shown in its normal display color and intensity, with all other visible layers grayed out or hidden depending to which Single Layer mode you switch. There are three Single Layer display modes available:
  • Gray – display all other layers in different shades of gray, the shade is based on the layer's current color.
  • Mono – display all other layers in the same shade of gray.
  • Hide – hide all other layers.

  If you are in Single Layer Mode, the current mode is displayed next to the Off/On buttons. In the image above, the current mode is Hide. This text is also a link to quickly access the settings where you can configure the available Single Layer Modes in the PCB Editor – Board Insight Display page of the Preferences dialog.

  Use the Masked Objects slider in the Mask and Dim Settings region of the View Options tab of the panel to control the brightness of other layers in the Gray or the Mono Single Layer modes.

• Show Grid (2D mode only) – the software has two display grids, referred to as the Fine and Coarse grids. The Fine grid is the current snap grid (as shown on the Status bar); the Coarse grid can be set to be equal or any whole number multiple of this grid.
  • Show Grid checkbox – the checkbox gives a quick way to toggle the visibility of both the Fine and Coarse grids on and off.
  • Show Grid color selector – allows the color of both grids to be changed. The color you choose is applied to the Fine grid, with the Coarse grid being automatically set to a lighter shade of the same color.

  The current Snap grid and the configuration of the Display grids are managed in the Grid Editor dialog. Press Ctrl+G to open the dialog or press G to display a quick-select menu of grid settings.

  Refer to the Working with the PCB Grids System page to learn more about grids.

• Projection (3D mode only) – determines the projection of the 3D view. Choose from:
  • Orthographic – choose this option to see the exact position of objects and text on the PCB without being obscured by surrounding objects.
  • Perspective – choose this option for a more realistic 3D view of the PCB.
• Show 3D Bodies (3D mode only) – controls the display of 3D Bodies. Use the Shift + Z shortcut to toggle this option on/off at any time when working in 3D mode. It also is possible to control the display of each model kind (extruded or generic) using an advanced setting. To do this, click the Advanced button on the System – General page of the Preferences dialog. In the Advanced Settings dialog, the Legacy.PCB.3DModelsShowMode preference controls the display of model types, supporting the Value – 0 (both), 1 (Generic only), 2 (Extruded only).

The Object Visibility section of the panel's View Options tab

• Object Visibility – as well as controlling the display of objects in the design space by toggling layers on and off, another approach is to control the visibility and transparency of objects based on their object-type.
  • Visibility – control the visibility of specific object-types by clicking the appropriate visibility icon. Click the All Objects visibility icon to toggle the visibility of all objects then enable the visibility of specific object-types.
  • Name – lists all objects that may be adjusted visually.
  • Draft – enable to display that object type as an outline.
  • Transparency – adjust the transparency of that object type using the slider bar or click the value and enter the desired percentage manually between 0 and 100 (0% is fully visible (solid); 100% is fully transparent (invisible)). Setting an object to transparent means you can see when one object covers another object, for example, where the end of a track segment meets a pad.
• Advanced – click to open the Object Visibility dialog, where you can set a common transparency level for a particular object across different layers and set different transparencies for different objects on a specific layer.

The 3D Settings section of the panel's View Options tab

Available only in 3D mode, these options are used to control the presentation of the board in 3D Layout Mode.

• Board thickness (Scale) – controls the vertical scale of the 3D view to make it easier to differentiate the layers, for example, when reviewing the layer-to-layer connections of an internal blind via. Drag the slider to set the vertical scaling between 1 and 100 times the actual board thickness.

• Colors – the default presentation is to render the 3D board using Realistic colors based on the Configuration currently selected in the General Settings section of this panel. Click the By Layer button to display the 3D view using the current 2D layer color assignments.

  Mechanical Layer pairs are included in the 3D View when the 3D Settings are using Colors – By Layer. Mechanical Layer pairs that are visible in 3D View can be configured in the Object Visibility section.
• Layer – click a color swatch to display the color selector. Refer to the Setting the Color section to learn more about using the selector.
• Transparency – use the sliders to control the transparency of each layer.

The Mask and Dim Settings section of the panel's View Options tab

To help manage the display of the large number of objects that can exist even in a simple PCB design, the PCB editor has the ability to fade objects that are not of interest. For example, if you click on a net in the Nets mode of the PCB panel and the panel drop-down is set to Dim or Mask, then all objects that do not belong to that net are faded. This allows you to more easily focus your attention on a specific design element, such as a net or a class of nets, class of components, objects targeted by a certain design rule, and so on.

• Dimmed Objects – objects that are currently dimmed retain their color but are faded. Use this slider to configure how much dimmed objects are faded. Dimmed objects can be edited.
• Highlighted Objects – when you have Dim enabled and click on an object in a panel, for example, a net in the Nets mode of the PCB panel, that net is also highlighted as all other nets are dimmed. Highlighted objects have their color whitened to make them stand out. This slider is used to control the amount of white added to the highlighted objects.
• Masked Objects – objects that are currently masked are displayed in gray and cannot be edited. Use this slider to configure how much masked objects are faded.

The Additional Options section of the panel's View Options tab

• Test Points – enable this option to display additional information on pads and vias that have been configured as testpoints. A Pad or a Via can be configured as a testpoint by enabling the Fabrication and/or Assembly Testpoint options in the relevant mode of the Properties panel. Testpoints are indicated by the addition of the string <Layer> Fab Testpoint or <Layer> Assy Testpoint to the pad/via.
• Status Info – enable this option to have summary information, such as coordinate position and layer, displayed in the Status Bar when hovering over an object in the design space.
• Pad Nets – enable this option to display the associated net name on a pad. Note that net names will only become visible if you are zoomed in close enough.
• Pad Numbers – enable this option to display pad numbers. Note that pad numbers will only become visible if you are zoomed in close enough.
• Via Nets – enable this option to display the relevant net name on a via. Note that net names will only become visible if you are zoomed in close enough.
• Via Span – enable this option to display the length in which the via is allowed to span. The properties of placed vias (diameter, hole size, etc) are then defined either by design rules, or manually. Note that net names will only become visible if you are zoomed in close enough. The layer numbers in the via span can be displayed inside all via types.
• All Connections in Single Layer Mode – enable this option to always display all of the connection lines when in Single Layer Mode. With this option disabled, all connection lines that do not start or end on the current layer are also hidden when switching to Single Layer Mode as it is assumed that they are not relevant.
• Net Color Override – each net can be assigned a color. To configure the color, double-click on that net's name in the Nets mode of the PCB panel; the Edit Net dialog will open. The color is automatically applied to that net's connection lines and also can be applied to the routing by enabling this option. Color is applied to the routing in accordance with the current settings in the PCB Editor – Board Insight Color Overrides page of the Preferences dialog, where you choose a Pattern option to define how the color is applied and choose a Zoom Behavior to define when the color is applied. Press the F5 shortcut to toggle the Net Color Override option on and off.
• Use Layer Colors for Connection Drawing – enable this option to display the connection lines using the colors of the start and end layers that the connection line travels between. The connection lines are displayed in pure layer color at the object they start/end at, morphing between those layer colors along the length of the connection line. This feature is helpful when you are routing a multi-layer board as it indicates the target layer that the connection being routed, must go to. Note that color morphing is only applied to connections that travel from one layer to another, if the connection starts and ends on the same layer it retains the assigned net color.
• Repeated Net Names on Tracks – enable to show repeated net names on tracks.
• Special Strings – when the option is enabled, any placed Strings that are formed from converted Special Strings will be superimposed (labeled) with the unconverted Special String name. Zoom in on a String to see its label overlay.
