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

A system having a processor is provided that visually manipulates objects on a touch screen responsive to inputs through the touch screen. The processor may receive a selection of a first object while a second object remains unselected. Also the processor may be responsive to first motion inputs representative of the selected first object being moved with a first motion that does not have a predetermined motion characteristic, to maintain a connection between the first and second objects while changing the positions of the first object and at least a first portion of the second object. In addition, the processor may be responsive to second motion inputs representative of the selected first object being moved with a second motion that has the predetermined motion characteristic, to break the connection between the first and second objects.

Object connection breaking system and method

A system having a processor is provided that visually manipulates objects on a touch screen responsive to inputs through the touch screen. Based at least in part on data representative of type and size for a plurality of prior objects displayed through a display device, the processor may determine that at least one input through the input device corresponds to a further object having a determined type corresponding to at least one of the prior objects and having a size within predetermined tolerances of corresponding to the at least one of the prior objects. Also the processor may cause responsive thereto the display device to display a replacement object in place of the further object having a size and shape corresponding to the at least one prior object.

Drawing object inferring 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 CAD system, method, and computer readable medium. A method includes receiving a graphic model and a selection of a symmetric constraint. The method includes receiving a selection of first and second curves of the graphic model, the selections indicating respective points on the first and second curves. The method includes determining a user's intent and applying a symmetric constraint between the first and second curves according to the user's intent. The method includes storing and displaying graphic model.
