Abstract: A method for user interaction in a CAE/CAD system comprises displaying to a user a graphical user interface (2) with a model display region (3) and a control region (5) for controlling operation of the CAE/CAD system, and an accept button (9). The accept button (9) can be in an active state, signifying that the CAE/CAD system is ready to perform operations defined by user input when the accept button (9) is clicked. When the accept button (9) is in the active state, the CAE/CAD system graphically indicates to the user an extended apply region (11) which, when a clicking operation takes place inside it, will cause the CAE/CAD system to perform the same operations as when the accept button (9) is clicked.

Abstract: The invention concerns a method for the creation of addendums (4) of tools for sheet metal formed parts (2).

Abstract: Processing steps are determined and optimized during the production of sheet metal forming parts, for example, using deep drawing/stretch forming processes. During the determination, using a computer-assisted design system, of process operations (PO1-PO6) for the description of forming processes on a forming part, the following steps are carried out: defining geometry models for the computerized description of a geometry of the forming part in a target state; defining several geometry operators (m1-m9, e1-e6), wherein one geometry operator (m1-m9, e1-e6) associates a geometry of an area of a first geometry model with a geometry of an area of a second geometry model, and the geometry operator (m1-m9, e1-e6) describes a transition from one of the two associated geometries to the other one; and defining several groups of respectively at least one geometry operator (m1-m9, e1-e6), wherein each one of the groups is respectively associated with a process operation (PO1-PO6).

Abstract: The invention relates to a method for determining a geometrical object for modeling the geometry of a metal sheet forming stage (1) in a CAD system. According to said method, an operator is defined which links a first geometrical model with a second geometrical model. The link is associated with a method for physically modeling a treating process which transfers a forming stage (1) from a corresponding first state into a second state. When the first geometrical model is modified, the second geometrical model is automatically updated in accordance with the physical modeling concept. The physical modeling concept for forming stages is thereby integrated into the static geometrical model environment of a CAD system. The physical modeling method is a method for calculating a border line (3) of a forming stage in an initial state prior to a forming process from a geometry of the border line (3) in a resulting state after the forming process.
