Systems, methods, and computer readable mediums. A method includes receiving a geometric model including at least one removal feature having at least one face, the removal feature being a feature that is removed prior to variational solving and recreated after a variational solution has been applied into the geometric model. The method includes designating at least one face of the removal feature as a remain variational face that will not be removed during a variational edit. The method includes adding a constraint to the remain variational face of the removal feature and performing the variational edit on the model to produce an edited model, including applying the constraint. The method includes storing the edited model.

Variational modeling with removal features

A method for a CAD system, a CAD system, and instructions for a CAD system. A method includes receiving an object model including a plurality of features. The method includes creating a blend as part of the object model, using at least one of the features, and removing the used features. The method includes creating a construction body corresponding to the object model, and storing the removed features in the construction body. The method includes performing a CAD operation on the object model using the features stored in the construction body.

Notch re-blend in an object model

A CAD system, method, and computer readable medium. A method for modeling a topological structure includes receiving a definition of a topological structure. The method also includes receiving a definition of a construction element and receiving a geometrical relationship between the construction element and an element of the topological structure. The method further includes receiving a change to the topological structure and, in response to the change, changing the first construction element according to the geometrical relationship.

Data processing system with construction geometry

Systems, methods, and computer readable mediums. A method includes receiving a geometric model including at least one removal feature having at least one face and designating at least one face as a remove variational face. The method includes adding a constraint that refers to the designated face. The method includes creating a second object corresponding to the removal feature and modifying the constraint to refer to the second object instead of the removal feature. The method includes removing the removal feature and performing a variational edit and solve on the model using the second object in place of the removal feature. The method includes recreating the model according to the variational edit. The recreated model can include the removal feature placed according to an updated location of the second object.

A method for controlling a data processing system, a data processing system executing a similar method, and a computer readable medium with instructions for a similar method. The method includes receiving, by an operating system executing on a data processing system, an execution request from an application, the execution request including at least one resource-defining attribute corresponding to an execution thread of the application. The method also includes allocating processor resources to the execution thread by the operating system according to the at least one resource-defining attribute, and allowing execution of the execution thread on the data processing system according to the allocated processor resources.
