Abstract: An interactive design system includes a design application that creates and models a geometry of an object. A programming language application defines engineering rules that may be associated with the object. The programming language application associates the geometry of the object with the engineering rules such that any change made to the geometry is automatically reflected in the engineering rules and any change made to the engineering rules is reflected in the geometry. The programming language application may also generate one or more knowledge features that can be used to verify that associated parameter constraints have not been violated as a result of a geometry or engineering rule change before applying the desired changes.

Abstract: According to one embodiment of the invention, a method for modeling a feature associated with a deformed material is provided. The method includes generating a first mesh having a model of a feature and a second mesh. A normal distance between a point on the model of the feature and the surface of the first mesh is measured. A location of the surface point of the first mesh that is used to measure the normal distance is determined. The determined location is used to locate the same surface point on the second mesh. A new location for a new point corresponding to the point on the model of the feature associated with the first mesh is determined. The new location is located at the distance as the determined normal distance, but along a normal vector that intersects the same surface point on the second mesh.

Abstract: A system, method, and computer program product for performing edits on related curves by automatically defining an associative entity that is upstream of either curve being connected. The connecting entity is called an ‘intermediary’. When creating a connection between curves, irrespective of where they appear in the associative tree, their geometry is made dependent on a common intermediary that is placed upstream of both curves in the tree. With this structure, both curves are related to the intermediary but retain all the properties of being connected to each other. Any edit performed to either curve is redirected through the intermediary such that both curves are simultaneously modified, providing the user with bi-directional propagation of edits. The user does not need to keep track of the order that the curves were related.

Abstract: A system, method, and computer program product which allows more versatile manual and automatic edits by embedding behaviors in the curve elements. These imbedded behaviors allow intelligent shape preservation during a curve edit. Each curve carries a behavior property that describes how it should react when edited. This means that the curve and graphics system have full knowledge of the right edit type to make, even when triggered by an outside source, such as a re-compute of an object at a higher level in the feature tree.
