Physical Materials

Access

This is the tab available for a 3D view configuration – accessed from within the View Configurations dialog. Access to this dialog depends on the current Editor:

• PCB Editor – use the Design»Board Layers & Colors command, or keyboard shortcut L.

• PCB Library Editor – use the Tools»Layers & Colors command.

Options/Controls

General

• Workspace Color – reflects the color used for the 3D background workspace. Click the color swatch to change the color as required through the Choose Color dialog.
   
  • Gradient – controls the color transition and direction of the 3D background workspace color. Placing the slide control in the center will stop any color transition and leave the background an even color.
     
• Board Thickness – controls the vertical scale of the 3D view to make it easier to differentiate layers when viewing the PCB internally. Drag the slider to the right to select between 1 and 100 times the vertical scaling. The number displayed on the right of the slide control represents the current scale being used. For example, a value of 10.0x would show the board ten times its actual height.

• Show Origin Marker – enable to display an origin marker when in 3D display mode. This marker represents the 0,0,0 position for the X, Y and Z-axes.

• Show Rooms – enable to show any room definitions in the 3D workspace. Rooms are shown as semi-transparent 'blocks' with a predetermined height.

• Show Board Cutouts – enable to show any board cutouts in the 3D workspace.

• Show Route Tool Path – enable to show the route tool path in the 3D workspace.

• Projection – determine the projection of the 3D view. Choose from:
   
  • Perspective – choose this option for a more realistic 3D view of the PCB.
  • Orthographic – choose this option to see the exact position of objects and text on the PCB without being obscured by surrounding objects.

Colors and Visibility

Choose the source for coloring of the various enabled (visible) layers – and objects thereon – for a 3D board:

• Realistic Colors – renders objects using more realistic, real-world coloring. A default set of colors will be loaded, presented to the right of each layer/object in the tab. With this option enabled, you are free to change the colors as required (see Layer Color below).
• Color By Layer Using Current System Colors – renders objects using the default 2D layer colors. The set of colors will be loaded, presented to the right of each layer/object in the tab. You cannot change these colors.

Copper is always visible for a board viewed in 3D. Choose which of the additional layers to make visible:

• Core – enable to show the PCB core as part of the 3D model. The core represents the physical dielectric and prepreg layers of the PCB wafer.
• Top Silkscreen – enable to show the top silkscreen as part of the 3D view of the board. The silkscreens show printed information on the top and bottom of the PCB wafer, such as manufacturing information, component designators and outlines.
• Bottom Silkscreen – enable to show the bottom silkscreen as part of the 3D view of the board.
• Top Solder Mask – enable to show the top solder mask as part of the 3D view of the board. The solder masks represent photo or silkscreen areas on the board that have no copper, i.e. areas that are not used for electrically connecting components to the PCB.
• Bottom Solder Mask – enable to show the bottom solder mask as part of the 3D view of the board.

• Layer Color – when using Realistic Colors, you are able to change the colors as required. Simply click on the color swatch to the right of any of the above entries (including Copper) and change the color using the standard Choose Color dialog.

• Opacity – use this slide control, associated to each of the options above (excluding Copper), to alter the opacity of the layer. The greater the opacity, the less 'light' passes through the surface. Move the slide bar to the right for greater opacity.

3D Bodies

• Show Simple 3D Bodies – use this field to determine how extruded (simple) 3D bodies will be displayed. Choose from the following available options:
   
  • Yes – extruded 3D bodies will be displayed.
  • No – extruded 3D bodies will not be displayed.
  • Use System Settings – extruded 3D bodies will be displayed or hidden according to the system setting Show Simple 3D Bodies, on the PCB Editor – Display page of the Preferences dialog.
     
• Show STEP Models – use this field to determine how 3D STEP models will be displayed. Choose from the following available options:
   
  • Yes – STEP models will be displayed.
  • No – STEP models will not be displayed.
  • Use System Settings – STEP models will be displayed or hidden according to the system setting Show STEP Models, on the PCB Editor – Display page of the Preferences dialog.
     
• Jump to system settings – click this link to access the PCB Editor – Display page of the Preferences dialog, from where you can view the current system settings for the display of 3D Bodies.

• Show Snap Point Markers – enable to display STEP model snap point markers. Snap Points are references to specific vertices on a STEP model. With three or more snap points added, you can reposition and orient a STEP model, using one snap point as an absolute reference and two others as alignment and plane references.

Components with both Simple and STEP Bodies

When there are both STEP model and extruded (simple) 3D body objects defined for a component footprint, use the settings here to determine which type to display. Available options are:

• Prefer simple bodies in components – display only the extruded 3D body object, not the STEP 3D body object.

• Prefer STEP in components – display only the STEP 3D body object, not the extruded 3D body object.

• Show both in components – display both extruded and STEP 3D body objects.
