Abstract: A method of modifying a CAD system model performed on a data processing system includes receiving a dataset of co-ordinates representing an article in 2d, or in 3d and receiving 2d or 3d constraints respectively, to be applied to any changes to the dataset of co-ordinates for the article. A modification to be applied to the dataset is received and combined with the relevant 2d and 3d constraints to produce a constrained modification for each of the article and associated article. The constrained modification is solved in 2d and in 3d to determine whether a solution exists in which all constraints are met. If the solve is successful, the constrained modification is applied to each dataset simultaneously and, updated datasets are stored. If the solve fails, the constraints may be reduced and the solve step repeated, or the process is terminated.

Abstract: A method of automatically identifying a network of geometries is performed on a data processing system. The method includes receiving one or more geometries having all or part of a network of geometries; recognizing adjacent tangencies to automatically identify another geometry in the network, or to determine that each geometry is connected to its neighbor through adjacent tangencies; repeating the recognition step until all geometries forming the network of geometries have been determined; and labelling the identified network as a slotdog.
