5. Compound specified entities
5.1 Specified entity made up of several surfaces
A functional or linking entity can be made up of several adjacent or separate, identical or similar elementary surfaces.
In this case, the indication UF for "United Feature" must be placed above the tolerance frame.
The entity specified with UF is considered as a single surface and therefore with a single tolerance zone.
