THE PROPOSAL OF A SYSTEM FOR DETERMINING THE CHARACTERISTICS OF MODELED SURFACES

The paper describes a methodology for determining the characteristics of the modeled surfaces in CAD systems. These characteristics are of major importance for development of process planning. These main characteristics can include surface dimensions, surface orientation and its type. The main role in determining the characteristics of areas is given to the design of a system for storing the CAD data which describe the surface. The file system format STEP AP214 will serve as input CAD data. The programming language C# 2008 will serve as a tool for CAD data processing using object oriented programming principles. For storing CAD data will be used related database management system MySQL 5.3.Original Abstract: U clanku se opisuje metodologija odredivanja karakteristika modeliranih povrsina u CAD sustavima. Te su karakteristike od bitnog znacenja za razvoj planiranja procesa. Mogu ukljucivati dimenzije povrsine, orijentaciju i tip povrsine. Glavnu ulogu u odredivanju karakteristika povrsina ima projektiranje sustava zapohranu CAD podataka koji opisuju povrsinu. STEP AP214 format sustava datoteke ce posluziti kao ulaz CAD podataka. Programski jezik C# 2008 ce posluziti kao alat za obradu CAD podataka primjenjujuci objektno usmjerene programske principe. Za pohranu CAD podataka koristit ce se sustav upravljanja bazom podataka MySQL 5.3.
