Definitions

  • the system wherein the computer system further saves a modified geometric representation of the modified geometric model into the at least one data file.
  • the system, wherein the computer system further removes the set of constraints from the geometric model.
  • the system, wherein the at least one data file is one of a geometric modeler transmit file, a modeling toolkit information file, and a solid model part file.
  • the system, wherein the geometric representation is in a boundary representation format.
  • the system, wherein the geometric model is a solid model.
  • the system, wherein the plurality of geometric conditions are calculated in a recursive manner to at least one level of recognition.
  • Figures 4a-4b illustrate a general concept of a software programming code embodied in a software application
  • FIG. 6 illustrates an exemplary solid model modification system.
  • the user using the software application 400 executes the necessary commands for the software application 400 to access the storage device 355 that is preferably a hard disk drive 600 having data related to a virtual representation of a solid model stored in the solid model data files 225 that are preferably accessible by the software application 400, the variational modeling toolkit 405, the 3D geometric modeler 410 and the component libraries 415.
  • the initialization of the interaction begins when the solid modeling application 605 creates an interaction object 625 and ends when the interaction object 625 is destroyed.
  • the solid modeling application 605 preferably populates the interaction object 625 in a model state with part instances, existing constraints and dimensions that are not available directly from the part, e.g., intra-part, and also specifies which dimensions are hard intent dimensions - those that can be floated and those that can be broken as defined by the user of the solid modeling application 605.
