Method for generating tightest revolve envelope for b-rep cad model
A recently granted patent (Publication Number: US11972524B2) discloses a method and system for generating the tightest revolve envelope for a Boundary representation (B-rep) Computer-Aided Design (CAD) model. The method involves receiving a 2-dimensional point cloud for each face of the CAD model, determining a concave hull shape for each face, combining these shapes to obtain a tightest revolve profile, and revolving it around the X-axis to create the final envelope. Additionally, the system includes a processor and memory to execute these instructions efficiently.
Furthermore, the method includes realigning the CAD model, generating a 3-dimensional point cloud, identifying void regions, transforming 3D data into 2D, and aligning the envelope back to the original orientation. The concave hull shape is determined by identifying boundary points and estimating the shape based on these points. Open regions in the profile are identified and joined appropriately. The system also allows for the identification of void regions and the transformation of 3D data into 2D for streamlined processing. Overall, the method and system aim to provide an efficient way to generate the tightest revolve envelope for CAD models, enhancing the design process in the field of Computer-Aided Design.
