A right mouse-click on any assembly in the Cimatron browser will offer an option to Rename Assembly Components. This is a mass rename tool that uses Excel, and it entails a two-step process. First, select the option to Edit component names. This opens an Excel spreadsheet with a row for each part. You will see many columns that can be edited, but of most importance are the ‘Old Name’ and ‘New Name’ columns. With some general knowledge of Excel, you can take advantage of the ability to replace or concatenate the new names. For example, you can add the job number to all parts. When done, save the Excel document. Going back to the Cimatron browser, choose the Rename Assembly Components a second time, and select the button to apply the new names to the project.
