Course Situation and Event Driven Models for Multilevel Abstraction Based Virtual Engineering Spaces Óbuda University John von Neumann Faculty of Informatics Institute of Applied Mathematics Lecture and laboratory 1. Abstraction in product definition László Horváth university professor
A prezentációban megjelent képernyő-felvételek a CATIA V5 PLM rendszernek, az Óbudai Egyetem Intelligens Mérnöki Rendszerek Laboratóriumában telepített installációján készültek, valóságos működő modellekről, a rendszer saját eszközeivel. Ez a prezentáció szellemi tulajdon. Hallgatóim számára rendelkezésre áll. Minden más felhasználása és másolása nem megengedett! CATIA V5 PLM rendszer a Dassult Systémes Inc. é s a CAD-Terv Kft segítségével üzemel laboratóriumunkban László Horváth UÓ-JNFI-IAM
