This presentation is intellectual property. It is available only for students in my courses.
The screen shots in this presentation were made in the CATIA V5 and the V6 PLM systems as well as the 3DEXPERIENCE platform at the Laboratory of Intelligent Engineering systems, in the course of active modeling process.
The CATIA V5 és V6 PLM systems as well as the 3DEXPERIENCE platform are operated at the above laboratory with the support of Dassult Systémes Inc. and CAD-Terv Ltd.

4. Representation of component connections
Between the child structures of an active structure.
Between a child structure of the active structure and a structure that does not belong to the active structure.
Structures are repositioned according to their parent structure.

5. Multidisciplinary engineering structure
Board form features can be created before or after definition of the board behavior on geometry.
Circuit board behavior
Electrical component behavior

6. Constraints in connection of shapes
Constraint mode
Driving: constraint drives constraints which are contextual with it.
Measured: constraint value comes from its definition and other constraints of the engineering connection.
Controlled: defines the constraint controlled by kinematics relation. The constraint value is defined between bounds.
Controlled constraint

7. Degrees of freedom (DOF)
Simple joints:
Revolute, 1R
Prismatic, 1T
Cylindrical, 1T+R
Screw, 1T+R, constrained
Universal, 2R,
Spherical, 3R.
Curve and surface defined joints
Slide along and roll around curve , 1T+1R
Slide along, roll around és roll, 1T+2R
Planar, 2T+1R
Point on curve, 1T+3R
Point on surface, 3R+2T

8. Constraint set for given type of connection
Set of constraints are defined for placing of solid body with required number of DOFs. In this case, DOF=0
Body which can move
1 translation
Coincidence of two surfaces mapped to faces.
Coincidence of two lines mapped to edges.
