Intended Use of Seams
Intersection Seams
Created in the Molded Forms task at the intersection of two parts, such as where a deck and a bulkhead intersect. Intersection seams are automatically created by the Execute Split command in Molded Forms.
Design Seams
Created in the Molded Forms task using a seam command. A design seam is used where a design property of a system is changing, such as where the thickness of a plate changes. Leaf systems under a single parent system are created.
Planning Seams
Create in the Planning task using Manage Block Intersections or in the Molded Forms task using a seam command. A planning seam designates the limits of blocks (large segments of a ship assembled in a single location) or smaller assemblies when the limits do not coincide with design seams.
Straking Seams
Created in the Structural Detailing task to designate separate physical plates, usually due to restrictions in plate sizes that can be ordered from the mill. Plate parts under a single leaf system are created.
