The commands in the seams category provide the methods to place one or more design or planning seams in the model. By using seams, you can split plate systems or profile systems at changes in mechanical properties. When a seam is split, the logical connections between the associated plate systems or profile systems are created. A seam object splits a system into separate leaf subsystems and is always associated with one or more systems.

  • Minimum height or distances are maintained by the software for objects that use Sketch 2D, such as seams by projection. For more information, see Minimum Distance.

  • When you create or edit a seam by projection, the dialog box title displays the plate system name using the format Plate System: <name of the plate system>:

  • You can change the default colors of seams, profile systems, reference curves, and knuckle curves to enhance visibility. For more information, see Modify Seam Display Colors.

Execute Split - Automatically creates intersection seams and splits systems by intersection and design seams. The split creates new subsystems. For more information, see Execute Split.

Manual Split - Places one or more intersection seams. For more information, see Manual Split.

Place Split - Divides a member system into multiple member parts while maintaining the design intent of the original member system. For more information, see Place Splits.

Split Seam - Splits a seam by intersecting seams. For more information, see Split Seam.

Split Root System - Splits a top-level (or root) plate or profile system into multiple root systems. For more information, see Split Root System.

Seam by Intersection - Creates a design or planning seam on the selected plate system by defining the landing curve of the seam as the intersection of the selected plate system and a grid plane. For more information, see Seam by Intersection.

Seam by Offset - Creates a design or planning seam on the selected plate system by defining the landing curve as being offset from an existing curve (such as another seam, plate boundary, profile system, or grid plane). For more information, see Seam by Offset.

Seam by Projection - Creates a design or planning seam on the selected plate system by projecting a 2D or 3D landing curve that you have sketched onto the plate system. For more information, see Seam by Projection.

Seam by Table - Creates a design or planning seam on the selected plate system by defining the landing curve as coordinates in a table. For more information, see Seam by Table.

Profile Seam - Creates a design or planning seam on a profile or on all profiles that belong to a plate system. For more information, see Profile Seam.

Profile Knuckle - Creates a manual knuckle on the selected profile system. For more information, see Profile Knuckle.

Un-Split - Merges plates into a single plate while leaving the splitting seam. Available on the Tools menu. For more information, see Un-Split.

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.
