A system, method, and computer program for modifying a solid model representation that is manipulated in a computer having software instructions for design, comprising: a computer system, wherein the computer system includes a memory, a processor, a user input device, and a display device; a computer generated geometric model stored in the memory in the memory of the computer system; and wherein the computer system accesses at least one data file having a plurality of geometric model definitions; converts the geometric model definitions into a visual representation of a geometric model; identifies an edit feature for modification on a body of the geometric model; calculates a modified geometric model with the modified edit, wherein the computer system removes the edit feature from an original body of the geometric model; creates a mapping for a plurality of faces from the edit feature to a new edit feature; applies the new edit feature to the original body, wherein the new edit feature is remapped to a new body and the new body is modified; and integrates the new feature with the modified geometric model; and appropriate means and computer-readable instructions.

703001000

A method for use in CAD modeling software to define product structure based on virtual components created independent from geometry and without the need to create files on disk. With the additional capability of assigning geometry to the virtual components of the product structure that sets and orients the virtual components and manages multiple occurrences of like components. Further, the virtual component are published into real components with automatic 3D file creation completed.

A system, method, and computer readable medium. A method includes receiving a model tree that defines a three-dimensional (3D) model. The model tree includes a history-free parent node that defines a complex 3D model and a plurality of history-based child nodes that define additional features that modify the complex 3D model. The method includes computing the 3D model, where the computed 3D model combines the parent node and the child nodes. The method includes displaying the computed 3D model as the complex 3D model modified by the additional features defined by the child nodes.

Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving a CAD model in the data processing system, the CAD model including at least a first blend that has an axis, a radius measured from the axis, and a plurality of unders. The method includes receiving a change to the radius of the first blend and selectively designating either the axis as fixed or the unders as fixed according to a property of the blend. The method includes modifying the CAD model by changing the radius according to the received change and the designated fixed axis or designated fixed unders, and storing the modified CAD model.
