A cover sheet is specified. The focus is on a functional defintion of the datum system, the handling of the screw connection (hole pattern) and the specification of a maintenance window.

The question of how to deal with cut or punched contours in practice is clarified. For this purpose, the feature principle (ISO 8015) is adapted by specifying an „Altered Default (ISO 8015).

In a second variant, the functional approach (datum system) is compared with a solution defining a non-functional datum system that is commonly used in practice.

Variants: Yes - 2 Variants

Difficulty Level: Variant 1: Suitability 1-2 | Variant 2: Suitability 1-2

Description of the level of difficulty (suitability for the user):

1 – The user has basic knowledge but has not yet used ISO GPS frequently in practice and takes first steps.

2 – The user has basic knowledge but is not proof about using ISO GPS and would like to gain more general confidence.
More „special“ or complex modifiers (these are usually listed in the example description) are applied selectively.

3 – The user has sufficient knowledge, can already use frequently used ISO GPS tools without difficulty,
and would like to deepen knowledge selectively based on typical functional descriptions,
which is usually also product-specific (e.g., snapping features (latching hooks) on a plastic injection-molded part, special demand hole patterns, i.e. multi-level patterns etc.)
used in the example (i.e., listed in the description) (e.g., direction only or certain combinations of dimensional tolerancing, as well as SIM or similar modifications).

4 – The user has extensive knowledge, has been working with ISO GPS for a long time,
and would like to learn about very specific applications or modification operations, which usually describe more complex functional requirements and products.
This requires, for example, situation features, reference elements, filter information, association modifiers etc.
