9. Communication with modeling procedures
Viewport
Provides sight into the model space.
Serves communication with model generation procedures.
No drawing, no editing, this is definition by control of model generation procedures.
Shape model
Mathematical representation constructed by control of mathematical procedures.
It includes a set of contextual surface represenattion in topological structure.

10. Object modeling of contextual features
General information schema
Model information schema
Object
Class (in taxonomy)
Paramaters
Relationships (contexts)
Procedures
Feature
Properties
Type with parameters
Representation. In case of shape feature, topology structured geometry.
Contextual chain for propagation of parameter changes.
Contextual connection
Parameter
Parameter
Feature driven model: feature acts on previously defined features though contextual connections of its parameters.
Model must be contextually consistent.
Real-time monitoring and simulation prevent the creation of erroneous results.
László Horváth UÓ-JNFI-IAM

11. Object modeling of contextual features
Theories and methods which are understood in the course of definition of model and experiments using active model.
Cartesian coordinate system and transformations.
Relating model space and plane in it.
Definition of shape using dynamic navigator.
Object and its parameters.
Feature, its attributes and parameters.
Context and contextual chain.
Active and passive parameter.
Constraint as context.
Offset of a surface.
Boundary representation at model definition.
Function of the space pilot device at the definition of model.
László Horváth UÓ-JNFI-IAM

12. Object modeling of contextual features
Work in a preselected plane. Dynamic navigator recorded so many important constraints

22. Object modeling of contextual features
László Horváth UÓ-JNFI-IAM

23. Object modeling of contextual features
Constraint active
László Horváth UÓ-JNFI-IAM

24. Object modeling of contextual features
Shape change is possible but real time simulation reject this modification.
Constraint inactive (changed parameter value)
László Horváth UÓ-JNFI-IAM

25. Object modeling of contextual features
Parameter „activity” changed back to true. The active constraint enforced the original shape using contextual chain.

Work in laboratory
Only actual task related activities are allowed on workstations.
Thematic laboratory tasks are mandatory.
Specially composed laboratory tasks do not require special skill in advance because teacher instruct actually.
This is a contextual system in which model is active in accordance with modeled contexts. Unwanted contexts active: do not use unnecessary objects and procedures at laboratory work.
Course program supposes continuous disciplined work.
