Individual Areas in Complex Group Structures
When the corresponding detail is a complex group structure (such as e.g. an assembly), individual dimensioning is not exclusively limited to production dimensions of single parts. Within an assembly, the contained component part groups can be dimensioned individually as well as it is the case with standard component part groups (see ‘Nested Dimensioning’).
In this case, several independent types of individual areas exist which can be managed separately. Each of these areas would correspond to the global area of the corresponding substructure if you displayed them as separate detail.
Assignment
It depends on the kind of 3D-modeling whether a component part can be reliably assigned to a local area. Most of the ProSteel functions create logical links between the involved component parts. By means of these links it is possible to determine which component part has been connected to another component part and by means of which connecting component parts this connection was realized (e.g. web angle). Thus, the assignment connected part and reference part is clearly defined.
When you cut however for example two shapes by means of a cutting line so that they match with each other, no logical link will be created there. In this case, you can force a relation of the component parts by the manual link.
The manual link should also be used when the automatically created link of a connection can - for whatever reasons - not be evaluated for determining the relations.
When the assignment cannot be determined and you selected a local reference of the component part, the component parts in question will be assigned to the global area.
