2. Locating a left shape
The presentation of this example evolves according to four points: declaration of tolerancing, integration of nominal and real geometry, declaration of tolerance zone membership, implementation. To take account of real part geometry (figure 12 ), it must first be declared in the data model. The points used in the declarations presented here are nominal points (since they are part of the declaration).
to make the text lighter, nominal and nominative terms are not systematically repeated.
This set of declarations can be carried out "out of cycle" by the metrologist. When the actual part is machined, it can be inspected directly. During the extraction process, the sensors "target" the declared...
