Connectors of a Parametric Part
In the parametric building environment of Content Builder, you can add connectors to a part. Connectors
enable the part to be connected intelligently to other building systems objects in your layout. You can define
one or more connectors for a part.
When you add a new pipe connector to a pipe segment or MvPart, the software automatically assigns
parameter values for CEL (connection engagement length) and AoD (angle of deflection). CEL and AoD are
assigned the following criteria:
■ Connector number associated with the CEL or AoD value; for example: CEL1 or AoD1 designating
connector 1
■ Description
■ Constant parameter type
■ Real number data type
■ Units:
■ For CEL: Drawing length in units (inches or millimeters)
■
For AoD: Degrees
■
Default value: 0.000
You place connectors in a left to right, then top to bottom orientation in the positive X-Y plane layout, as
shown next.
Fitting connector orientation
The Piping domain includes fittings with female connectors. Connection types with female connectors
include hub, bell, and mechanical joint. The female connector on an elbow or a tee is designated as connector
2. The female connector on non-symmetric fittings, such as crosses, is designated as connectors 2 and 4.
When you add a new pipe connector to a pipe segment or MvPart, the software automatically adds CEL and
AoD parameters.

parametric fittings content. See also Connection Types for Pipe and Pipe Fittings on page 266 for fitting types in
the Piping domain.
