1. A computer implemented method for designing a web (4) linking parts (3) to a carrier (2) in a sheet metal strip (1) that is processed in a progressive die process, the parts and the carrier being sheet metal sections of the sheet metal strip, the web comprising links that link the parts to the carrier, and the method comprising the steps of
processing input actions from a user, the input actions specifying parameters of web primitive elements, the web primitive elements comprising at least connections (5), each connection (5) representing a link between sheet metal sections;
the user input actions specifying, for each connection (5), a first connection point (13), at which the connection (5) is joined to a first sheet metal section, and a second connection point (13), at which the connection (5) is joined to a second sheet metal section;
the user input actions specifying a deformability parameter associated with a connection (5), for modifying a spring constant of the connection (5) in a direction between the first and second connection points (13), the spring constant relating forces acting at the first and second connection points in the direction between the first and second connection points to relative displacements of the first and second connection points in the direction between the first and second connection points.
