THREE-DIMENSIONAL CAD MODEL PART SEARCH METHOD AND THREE-DIMENSIONAL CAD MODEL SEARCH METHOD

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional CAD model similarity search method capable of performing search for every component configuring complicate three-dimensional CAD data, and performing various types of search such as accessing the three-dimensional CAD data as a finished product from the components.;SOLUTION: A three-dimensional CAD model part search method includes: an arrangement step for three-dimensionally arranging three-dimensional CAD data; a disassembly step for disassembling the three-dimensional model for every component of the CAD data to obtain element data; sinogramming step for processing the element data to obtain a sinogram; an association step for associating the sinogram with the original three-dimensional CAD data; and an extraction step for performing search for each three-dimensional data with the sinogram as a mark to extract matching components by performing collation for every component data, or to extract the three-dimensional CAD data associated with the components.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
