Individual parts can be grouped into part families. Using part families can help with the positioning and detailing processes. For example, you can allocate a position number prefix or color to all parts in a family. In addition, components belonging to one family class can have a common detail style for detailing.

Part families are another structuring variant of the construction. The belonging to family classes permits an automatic allocation of position number prefixes as well as a differentiation of the constructive groups by different colors. In addition, components belonging to one family class can have a common detail style for detailing.

Each element can exist only in one family class. This means if it is assigned to another family class, it will be removed from its former family class. New is the possibility to assign certain colors and line types for detailing to the members of a part family.

For example, you can assign another color to the girders of a 2D depiction than that assigned to the supports.
