3D CAD DATA CONVERSION METHOD, DEVICE, AND PROGRAM

摘要

A 3D CAD data conversion method converts 3D CAD data into an intermediate file of the standard format by a data conversion process. The method automatically detects a portion of a non-manifold body from the 3D CAD data and adds an arbitrary numeric value satisfying the relationship (tolerance value (mm)) < (arbitrary numeric value (mm)) = (value greater than the tolerance value) as internal data to a portion of the non-manifold body in linear contact or point contact before performing the data conversion process.
