Abstract: Systems and methods for efficient duplication of objects in a CAD model. A method includes receiving a CAD model including a plurality of objects in a model space. The method includes receiving a selection of a first object of the plurality of objects. The method includes receiving a selection of at least one target in the model space. The method includes deriving a transformation matrix corresponding to the model space. The method includes deriving a relative transform according to the transformation matrix and the first object. The method includes deriving a target transformation matrix for each of the targets. The method includes creating, for each target transformation matrix, a duplicate object located in the model space such that the transform between the corresponding target transformation matrix and the duplicate object is equal to the relative transform. The method includes storing the CAD model including the duplicate objects.

Abstract: A system and method for improving user feedback during graphical edits by dynamically propagating each incremental edit through the dependency tree and displaying real-time updates to the graphic representation as the updates are being made. By updating the image through the entire dependency tree at the earliest possible time, without waiting for the user to complete his edit or to perform an action which manually indicates an update, the user is given improved feedback during the editing process.

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.
