Compare two PCB designs

This example shows you how to compare two PCB designs using interactive tables and the 2D viewer.

Before following these steps, you need to log in to the web application.

  1. Click Compare to open the comparison functionality.
    If you are not logged in, nothing happens when you click the command.
  2. On the top-left corner of the Compare loading page, click or drag and drop the file that contains the first PCB design revision.
    You can also choose two PCB design revisions from the database table.
  3. On the top-right corner of the Compare loading page, repeat step 2 to upload a second PCB design revision.
  4. Click Compare to start comparing the two models.
    The main Compare page opens with comparison information for the designs and their entities on their respective tabs.
  5. On the Information tab, in the table, explore the number of PCB assembly changes for each entity type.
  6. (Optional) To visualize the chart in different formats, in the Entities and Count columns, select all the entities and their counts, right-click, and select your preferred chart format, for example, Chart Range→Column→Stacked.
  7. Click the PCB tab and compare the thickness, sizes, areas, and layers of the two PCB boards.
    When you select a layer in the PCB table, it is highlighted in the corresponding board thickness viewer.
  8. On the Components tab, explore the component comparison table.
    The Status column indicates whether the component is unchanged, modified, added or deleted.
  9. For modified components, click to display more information about the changes.
  10. On the Holes tab, explore the holes table.
    The Status column indicates if the component was unchanged, modified, added, or deleted.
  11. For modified holes, click to display more information about the changes.
  12. Click the Viewer tab and inspect the graphical display of the changes between the two revisions.
    The application displays the added, modified, and deleted components. It also highlights the modified holes using the color code defined in the settings.
  13. In the graphics window, click rewind to display the first PCB design revision.
  14. Click play to animate the modification.
  15. On the viewer command ribbon, click Overlays Toolbox to open the Overlays toolbox.
    In the Comparison Results group, in the Components Changes sub-group, you can display or hide the comparison results of the components mounted on the top, bottom or other layers of the PCB.
    You can also display or hide any hole and area changes from their respective sub-groups.
  16. On the viewer command ribbon, click Overlays Toolbox to close the Overlays toolbox.
  17. In the graphics window, click forward to display the second PCB design revision.
    You can use the viewer functionality to explore the design changes in detail.
