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.

Modelling method and system

Method and system for multiple views computer-aided-design including propagation of edit operations across views while ensuring constraints consistency

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.

Variational modeling method and system for editing of geometric objects

Methods for identifying geometric clones in a modelling system, or simulating modifications to construction of a multi-part product and corresponding data processing systems and computer readable media. A method includes choosing a template of a geometric form and generating and storing a map of the template, identifying a candidate geometric form in the system and exploring the identified candidate geometric form from a start point until returning to the start point or reaching a branch. The method includes generating a map of the explored candidate geometric form, comparing the map of the explored candidate geometric form with the map of the template and labelling the candidate geometric form as a clone if it matches a predetermined portion of the template.

System and method for identifying clones

Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving a CAD model in the data processing system, the CAD model a plurality of features and constraints, including optional constraints. The method includes receiving a user operation to manipulate a seed feature, and identifying a plurality of optional constraints corresponding to the user operation. The method includes sorting the optional constraints and applying a sorted optional constraint. The method includes performing the user operation according to the applied constraints to produce a modified CAD model and storing the modified CAD model.
