A computer-aided design (CAD) system may support anti-constraint configuration and enforcement for CAD models that represent physical objects. Anti-constraints may specify given constraints not to be applied for components of the CAD model, and the CAD system may update components of the CAD model without applying the constraints specified in anti-constraints applicable to the CAD model components.

Anti-constraint configuration and enforcement for computer-aided design (CAD) models

Methods for modifying geometric models and corresponding systems and computer-readable mediums. A method includes receiving a geometric model, the geometric model including a plurality of curves. The method includes receiving a selection of one or more curves of the plurality of curves, finding at least one other curve of the plurality of curves that is related to the selected curve, and finding relationships between the selected curve and the other curve(s), including adding the selected curve, the other curve(s), and the relationships to a selected curve set. The method includes pre-processing the selected curve set, including de-activating a set of constraints for the geometric model. The method includes receiving a modification of the selected curve and modifying the selected curve set to produce a modified geometric model and modified selected curve set. The method includes post-processing the modified selected curve set, including re-activating and applying constraints for the geometric model.

Modifying constrained and unconstrained curve networks

A system and method is provided that facilitates the selection of individually selectable three dimensional objects displayed through a display device. The system may include at least one processor that is configured to determine at least one path that traverses the objects based on at least one motion input received through an input device. The processor may also cause at least two of the objects to be selected in a group while at least one of the objects remains unselected based on an amount of a surface area of each object that was traversed by the at least one path. In addition, the processor may cause at least one operation to be carried out on the group of at least two objects that are selected and not on the at least one object that remains unselected based on whether the objects are selected, responsive to at least one operation input received through the input device.

Object selection system and method

Methods for constraining a geometric model and corresponding systems and computer-readable mediums. A method includes creating a rigid sketch group that includes some or all of the plurality of curves and receiving a user selection of first option rules or second option rules. The method includes editing the rigid sketch group according to the selected first option rules or second option rules. The method includes displaying the geometric model by the data processing system, including displaying the edited rigid sketch group.

Rule-based constraint interaction in geometric models

A method for editing a position of a selected design element in a constraint network. The method includes receiving the selected design element in a geometric model from a user, searching a database for a positioning group related to the selected design element, and adding the selected design element and the positioning group related to the selected design element into a work collection. The method then includes searching the database a second time for reference positioning groups and reference design elements referenced by constraints of the positioning group and design elements in the work collection and adding the reference positioning groups and the reference design elements discovered by the second searching into a context collection. The method then further includes loading all the constraints for the positioning groups and the design elements which were added to the work collection.
