Geometry for Connection Points
MEP discipline equipment families can include connectors for ducts, pipes,
conduit, and even cable tray if necessary. These connectors are added to
define the function of the equipment from an engineering standpoint.
Connectors are added by one of two methods: either by placing them on a
face of the solid geometry or by associating them with a workplane within
the family. When you associate a connector with a workplane, it can be
located anywhere in that plane. Connectors placed with the Face option on
the Placement panel of the contextual tab will automatically attach to the
center of the face.
Using the Face option is useful when you know that the connection point is
always at the center of the geometry—because if the geometry changes size,
the location of the connector will adjust, or if the geometry changes location
within the family, the connector will move with it. This method requires less
constraint within the family for the location of the connector, but it may be
necessary to model extra geometry to provide a correctly located face for a
connector.
