Creating geometry for the location of connectors is an easy way to manage
notonlyconnectorlocationsbutalsoconnectorsizes.Thesizeofaconnector
can be associated with the size of its geometry host face. This allows for
accurate modeling of connection points of different family types within a
family.
Geometry used for connection points may be more easily dimensioned than
connectors themselves because youcandimension totheedgesofgeometry,
whereas connectors can be dimensioned only to their center points. For
example, if you have a rectangular duct connection that varies in size yet
needs to maintain a certain distance from the edge of the unit, you can
model geometry that is constrained to the dimensional requirements and
then host the connector to that face. Figure 19.9 shows an example of an
extrusion used in this manner. The 0′-6″ (150 mm) and 0′-4″ (100 mm)
dimensions are locked to hold the extrusion in place when the Unit Height
and Unit Width parameters are changed and when the SupplyHeight and
SupplyWidth parameters change.

Using extrusions for connection points can make it easier to identify where
to connect pipes, duct, or conduit to your equipment when working with the
family in a project. More information on connector geometry is provided
in the section “Adding Connectors to Equipment Families,” later in this
chapter.
