CAD data identity determination component - Logical smart

Abstract

In the CAD drawing standard of the Ministry of Land. Infrastructure and Transport, it is clearly written that the CAD drawing's exchange format will conform to the international standard ISOl0303-202 (STEP/A P202). On the other hand, at the Japan Construction Information Center's (JACIC) CAD Data Exchange Standard Development Consortium (SCADEC: Standard CAD data exchange format in Japanese Construction field), exchange format (SXF:SCADEC eXchange Format) based on STEP/AP202 was developed. In the future, for the electronic delivery of CAD data related to construction, SXF will be adopted. In addition, in Osaka Prefecture, securing CAD data related to construction is raised as an issue for electronic delivery system/information sharing system. However, in the current situation, system that can distinguish identity of 2 distinct CAD data does not exist. For this reason, in this research, a system, specifically called Logical Smart, that determines the identity of CAD data by using SXF is developed.
