Performing Product Model Compare

You can use CAM Compare to compare two versions of an ODB++ product model. The comparison process consists of reading in the reference data, matching copper layers (if required), and comparing.

Note:

In many cases, comparison stages are performed automatically.

Tip

You can click the Show Next Result tool at any time to perform the remaining stages of the comparison process.

Procedure

Open CAM Compare as appropriate for the application you are running.
The comparison pane of the CAM Compare window lists the layers of the current product model in the ODB++ Layer List column.

Tip
If you have previously imported data, and you want to read in different data instead, click the Clear CAM Layers tool .
Import the reference ODB++ product model:
1. Click the Open Reference ODB++ job tool and select the product model.
  The Job list dialog box opens.
2. Select the product model and click OK.
  The Step list dialog box opens.
3. Select the step and click OK.
  The layers of the reference product model are matched with the layers of the original product model, based on their position in the product model matrix, and on their type and context. They are listed in the CAM Data column.
  
  The Match column indicates the status.
If necessary, drag layers into the correct position.
Click the Compare tool to compare the reference layers to the original layers.
