You can use this function to manipulate the displayed image to achieve the needed view of the model using the display control capabilities of the Model Viewer. You can also filter the contents of the model and to display only those model elements that pass the filters.

The ECAD input file contains a PCB Layout model. This is a 2D model with layering. It may also include a schematic model.

Features

Manipulating ECAD PCB Layout View

The Model Viewer provides the following ways to manipulate the PCB Layout image displayed in the viewport:

  • Pan the image in any direction

    To pan the image, depress the left mouse button (or the left and right mouse buttons), drag the cursor in any direction, and release the mouse buttons. For small incremental horizontal movements, hold down the Left or Right arrow keys.

  • Center and zoom an element

    To center and zoom an element, double-click on the element in the viewport or double-click on the element in the Elements List.

Filtering ECAD PCB Layout View

The Model Viewer provides the following ways to filter the contents of the PCB Layout image displayed in the viewport:

  • Switch ECAD view modes

    To switch to the Schematic View mode, choose the Schematic Sheets icon on the left hand toolbar; double-click on a schematic sheet entry. This will display the selected schematic sheet in the viewport with the label for the currently selected component centered and zoomed. A schematic sheets entry displayed in black contains the currently selected model component. A schematic sheets entry displayed in red does not contain the currently selected model component.

  • Layer control

    To filter the contents of the model image by layers, choose the Layers icon on the left hand toolbar; select a checkbox to turn on the display of the contents of that layer; unselect a checkbox to turn off the display of the contents of that layer.

  • Flip the board

    Flipping the board automatically filters the contents of the model image by turning off the display of the layers currently displayed and turning on only the layers associated with the other side of the board. It also rotates the viewpoint 180 degrees about a horizontal axis along the length of the board and halfway up the height of the board. To flip the board, choose the Flip Board icon. This will flip the board and toggle the state of the icon. When the icon is on, it indicates that the bottom of the board is being displayed. When the icon is off, it indicates that the top of the board is being displayed.

  • Select / unselect element checkbox
