Conduits and T-Bars
There are two additional special types of object: T-bars and Conduits. (Note: Conduits are not supported in the current release of Blueprint)
Conduits
Where ordinary connections can be bundles from one object to another (see Dimension above) Conduits are bundles of connections between several objects. Conduits must use named endpoints to define which connection ends are paired.
Conduits behave similarly to connections in that they can be routed around objects by dragging their line segments and end points, but they are connected to as if they were objects.
TBars
T-Bars are extensions of an object's connection face when that face only has space for one connection. This allows multiple connections to be made on an otherwise limited face. Since all connections to a T-Bar connect to a specific face of a specific object no special naming is required.
