  • Patent number: 9342070
    Abstract: In a method for designing a sheet-metal-forming process in which a sheet-metal part is formed, a visual representation of the sheet-metal part is computed and displayed. Visual labels are displayed, each label being visually linked to the representation of a feature of the part. The labels indicate one or more processing units of the sheet-metal-forming process that are assigned to the features. The labels can also indicate process operations to which these processing units are assigned.
