Use an assembly offset to associate a point on a subassembly with a secondary alignment. This is especially useful in a corridor region such as a knuckle or lane widening.
Figure 4: Assembly with offset
Figure 4 shows an assembly with an offset on the curb subassembly on one side of the roadway. This offset can be associated with an alignment that defines the outside road edge as it widens to accommodate a turn lane or off-ramp.
