PROGRAMME
Purpose and principle of functional dimensioning.
Functional study of a whole.
Identification of static links
Identification of dynamic links

(For further definition of geometric specifications)
Inventory of functional areas and assignment of functional specifications (type ES, ED)
(For later definition of specific surface finishes)
Materialization of condition dimensions
(For a later definition of the tolerance of linear and angular dimensions)
Reminder on odds chains
