Abstract
A computer-implemented solid modeling system provides a graph-based method that sculpts solids with sheet bodies by performing a selective Boolean operation on a part body and one or more sheet bodies, wherein faces of the sheet bodies separate the part body into regions of space such that the regions are separated from each other by the faces of the sheet bodies. Cells thus formed are selected for inclusion or exclusion in the resulting solid as is specified by an option (“join” or “cut”).
Claims42
A method for sculpting a part body with sheet bodies in a computer-implemented solid modeling system, comprising:
- (a) performing a selective Boolean operation on a part body and one or more sheet bodies, wherein faces of the sheet bodies separate the part body into regions of space such that the regions are separated from each other by the faces of the sheet bodies, wherein the performing step (a) comprises performing a pre-processing phase to create a cellular topology graph of tool and blank bodies created from the part body and the sheet bodies, performing an analysis phase to categorize and convert cells in the cellular topology graph;
- and performing a post-processing phase to integrate results from the analysis phase to create an output part body.
An apparatus for sculpting a part body with sheet bodies, comprising:
- a computer;
- and
- a solid modeling system, executed by the computer, having logic for:
- (a) performing a selective Boolean operation on a part body and a sheet body, wherein faces of the sheet body separate the part body into regions of space such that the regions are separated from each other by the faces from the sheet body, wherein the logic for performing (a) comprises logic for performing a pre-processing phase to create a cellular topology graph of tool and blank bodies created from the part body and the sheet bodies, performing an analysis phase to categorize and convert cells in the cellular topology graph, and performing a post-processing phase to integrate results from the analysis phase to create an output part body.
An article of manufacture embodying logic for sculpting a part body with sheet bodies in a computer-implemented solid modeling system, the logic comprising:
- (a) performing a selective Boolean operation on a part body and a sheet body, wherein faces of the sheet body separate the part body into regions of space such that the regions are separated from each other by the faces from the sheet body, wherein the performing step (a) comprises performing a pre-processing phase to create a cellular topology graph of tool and blank bodies created from the part body and the sheet bodies, performing an analysis phase to categorize and convert cells in the cellular topology graph, and performing a post-processing phase to integrate results from the analysis phase to create an output part body.
