Graphical object generation and regeneration
A method of propagating changes in a design model identifies a change to a changed element, creates steps to carry out the change, creates additional steps based on the change and on relationships between the changed element and other elements in the design model, and executes the steps to alter the model in a manner that reflects the change. The steps may be created in a manner that depends on other steps that have been created. A system for regenerating a design model comprises a model element, a step propagator, and a step executor. The step propagator receives a first step that represents changes in the model element, and produces a second step that represents other changes in the model element that are dependent on the first step, and the step executor executes the first and second steps.
1. A computer-implemented method of propagating changes made in one data element to a related data element, comprising:
accumulating, by a processor, the changes made in the one data element using a unique element ID;
identifying, by the processor, a predetermined plurality of possible different sets of changes that may be made in the related data element;
selecting, by the processor, a most appropriate set of changes by employing a predetermined selection standard; and
testing, by the processor, the selected set of changes to determine whether it is an appropriate set of changes, wherein testing the selected set of changes comprises verifying the one data element and the related data element for constraint satisfaction.
2. The computer-implemented method of claim 1 , wherein the one data elements includes a plurality of subelements.
3. A computer storage medium storing a software application executable to cause one or more computers to perform operations of propagating changes made in one data element to a related data element, the operations comprising:
accumulating the changes made in the one data element using a unique element ID;
identifying a predetermined plurality of possible different sets of changes that may be made in the related data element;
selecting a most appropriate set of changes by employing a predetermined selection standard; and
testing the selected set of changes to determine whether it is an appropriate set of changes, wherein testing the selected set of changes comprises verifying the one data element and the related data element for constraint satisfaction.
4. The computer storage medium storing the software application of claim 3 , wherein the one data element includes a plurality of subelements.
5. A system comprising:
one or more computers configured to perform operations of propagating changes made in one data element to a related data element, the operations including:
accumulating the changes made in the one data element using a unique element ID;
identifying a predetermined plurality of possible different sets of changes that may be made in the related data element;
selecting a most appropriate set of changes by employing a predetermined selection standard; and
testing the selected set of changes to determine whether it is an appropriate set of changes, wherein testing the selected set of changes comprises verifying the one data element and the related data element for constraint satisfaction.
6. The system of claim 5 , wherein the one data element includes a plurality of subelements.
