> ## Adding Parts

> To add a part, click the Add Part button or select File, Add CAD File.

> NOTE: If these options are disabled, the job is not editable. See Why Can't I Make Changes in the Preview Window?

> The system displays a file browser dialog box which you can use to select one or more parts.

> After you select the parts, the system adds them to the print job and automatically places them.

> #### Verification Strip (for InVision HR Printers Only)

> The InVision Client software automatically adds and places a "verification strip" part on InVision HR printer platform. The verification strip is required to ensure accurate high-resolution printing on the InVision HR.

> You can select the verification strip part in Preview and view its properties, however, you cannot change its size, position, or rotation angle-and you cannot delete it.
