The red lines are feature lines that connect
like points on each assembly insertion.
understanding the Corridor Surface
As you view the assembly insertions along the 3D chain previously shown in
Figure 9.3, imagine this as the structural framework of a ship or an airplane. With
the framework in place, now imagine the hull or fuselage being installed on the
vessel. This is a great way to envision the role of a
corridor surface
(see Figure 9.5).

A corridor along with its corridor surface,
shown in 3D view
Although they appear in Prospector like other surfaces,
corridor surfaces
are
built directly from the corridor and maintain a link to the corridor. They can be
displayed as contours, used to create surface profiles, and perform every other
function normally associated with surfaces.
Creating an Assembly
As mentioned previously, an assembly consists of smaller components called
subassemblies
. To create an assembly, you begin by creating an assembly base-
line, which is represented by a simple vertical line in your drawing with a single
