Three-dimensional geometry processing system and method for CAD apparatus restricted in surface representations to import solid data

摘要

A three-dimensional geometry processing system and method for converting boundary representations solid data in a first format into output solid data in a second format which includes a surface conversion and division mechanism configured to convert surface information in the boundary representations solid data into geometry data, and divide a surface which needs to be divided according to restriction of the second format to generate topology information of the divided surfaces, a topology information addition mechanism configured to map topology information of the boundary representations solid data to the topology information of the divided surfaces, and a surface join mechanism configured to join the divided surfaces based on the mapped topology information to generate the output solid data in the second format.
