CAD DATA CONVERTING APPARATUS, 3D CAD MODELING SYSTEM USING THE SAME, AND DESIGN METHOD OF 3D PIPE USING THE SAME

摘要

PURPOSE: A CAD data converter, a three-dimensional CAD modeling system using the same, and a three-dimensional pipe designing method using the same are provided to detect interference of a peripheral structure by automatically generating a shrink deformation 3D CAD model. CONSTITUTION: A result file input unit receives a result file of a stress analysis program. A CAD(Computer Aided Design) data generating unit generates a shrink deformation file which uses a three-dimensional CAD program by recognizing a file structure(240). The shrink deformation file is generated based on an initial coordinate of a pipe and fitting information from a result file of the stress analysis program.
