In the CAD system which creates two-dimensional drawing from

摘要

PROBLEM TO BE SOLVED: To provide a technique expressing the details of a hole machining section when creating a two-dimensional drawing from three-dimensional CAD data including the hole machining section.;SOLUTION: A hole information intermediate file including a hole ID code specifying a hole format and hole dimension data is generated from the three-dimensional CAD data. A hole cross section template where the hole ID code is adapted as a retrieval key is extracted from a template storage section. Hole cross section drawing data are generated based on the hole dimension data and the hole cross section template. A two-dimensional drawing is output, where the hole cross section based on the hole cross section drawing data is built into a projection chart based on the projection drawing data.;COPYRIGHT: (C)2008,JPO&INPIT
