Transformation Functions

The transformation functions are all subfunctions of two of the nesting functions: NEST and TRANSFORM. Consequently, they cannot be used without actuating one of the two main functions first.

The transformation functions are used in a transformation sequence, when a plate part (or possibly a group of plate parts) is to be positioned. Thus, they are actuated one after the other, until the part is properly positioned.

The transformation functions are of two kinds: dynamic and static. A dynamic function implies that the part is moving on the screen during the transformation (for example, rotating). A static function (for example, mirroring) implies that only the positions before and after the function can be seen by the operator.

There are two dynamic functions: ROTATE DYNAMICALLY and MOVE DYNAMICALLY, of which one is always modal. This is normally the last one used but in the initial phase of a transformation sequence, that means, when a part (or group of parts) has been newly appointed to be transformed, MOVE DYNAMICALLY is the modal one. To switch from one to the other, OPTIONS should be given. To actuate the modal one, however, a position at the part (or group of parts) currently to be transformed shall be given. Depending on which one of the two functions that is modal, the part can then be moved or rotated. The next given position will uncouple the part and allow for a new choice of transformation function (or acceptance of the position). In these dynamic transformations the toggling between envelope and full display is solely controlled by mouse-button2.

The static functions will either be executed immediately after actuation (for example, MIRROR U will immediately cause current plate part to be mirrored) or will prompt the operator to give some additional information to the system (for example, positions, angles).
