  1. Óbuda University John von Neumann Faculty of Informatics Institute of Applied Mathematics CourseSituation and Event Driven Models for Multilevel Abstraction Based Virtual Engineering Spaces Lecture and laboratory 1.

  2. Ez a prezentáció szellemi tulajdon. Hallgatóim számára rendelkezésre áll. Minden más felhasználása és másolása nem megengedett! 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. CATIA V5 PLM rendszer a Dassult Systémes Inc. és a CAD-Terv Kft segítségével üzemel laboratóriumunkban LászlóHorváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/

  3. Principle and modeling by features 1990-2000 Information loss free information exchange IPIM, product model (ISO 13303), AP Engineering task specific model objects Form feature driven product definition Demand Solution Feature Modifies model by a definite manner through contextual connections with previously defined features. Feature driven modeling Construction of product model by a series of features. LászlóHorváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/

  4. Three leveled modeling of form features Form Feature Information Model (FFIM) Level 1: Application feature Application specific attributes Level 2: Form feature The form feature itself Level 3: Form feature representation Boundary representation László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/

  5. Groups of form features These groups are defined according to modification principle and method. In practice, these groups are divided to subgroups according to the purpose of the modification.
