18. Engineering Connection Between Solid Components Engineering connection feature for components in the product structure on the physical (P) level of model Can be defined: On one component Between two or three components. Component: Shape Part Product Defined by: a set of components, an orientation or not, a set constraints László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/ Methodology of engineering connection is considered as it is included in V6 PLM system. This is representative and can be well experienced during laboratory exercises. Engineering connection is applied on model during PLM update. Consequently, not correct engineering connection will be detected in error during the PLM update.

19. Parameters Type Constraint Type Mode Value Support Lock/unlock Orientation Connection property Engineering connection type Analytical (e.g. prismatic, revolute, cylindrical) Defined by curves and surfaces (e.g. point on curve, point on surface, slide curve, roll curve.) Combined (e.g. screw, gear) Constraint Type Positional (coincidence, contact, offset) Angle (Angle, parallelism, perpendicularity, hinge) Coupling (e. g. fix (relative together, together, fix, symmetry) Curve (curvilinear distance, roll, slide curvilinear) László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/ Engineering Connection Between Solid Components
