This best practice illustrates how to model interior openings as sketched boundaries and include the decks that define the base of the openings in the bulkhead boundary list, allowing the transverse bulkhead to be modeled as one plate system.

You want to create a transverse bulkhead as one plate system, which is split by the decks and longitudinal bulkheads, and contains large openings outboard of longitudinal bulkheads. The challenge in modeling the transverse bulkhead is how to model the openings. If you create an opening, the base of the opening is coincident with the intersection seam, which sometimes causes detailing to fail.

Instead of using Place Opening to model the openings, model the interior openings as sketched boundaries and include the decks that define the base of the openings in the bulkhead boundary list. The transverse bulkhead to be modeled as one plate system.

The following example uses sketched boundaries to create interior openings that are coincident with intersection seam:

1. Import the hull using Imported Plate System .

2. Assuming grid planes that are 1 meter apart, create decks D3, D21, D30, and D35, bounded by the hull and reference frames x = 40 and 60M, using Planar Plate System .

3. Create longitudinal bulkheads L10 and L-10, bounded by the hull and the D35 deck system, also using the Planar Plate System command.

4. Using Planar Plate System , create a transverse bulkhead at F50:

1. Set Continuity to Intercostal.

2. As the boundaries, select the hull, D21, D30, and D35, and then click Sketch Boundary Curve .

4. Draw the opening boundaries as shown.

5. Click Finish.

The software starts the Ambiguity Solver. Three cells are presented (between hull and D21, between D21 and D30 and between D30 and D35).

6. Select all three cells, and then click Finish again.

The bulkhead is created as shown.

5. Run Execute Split .

The software creates the 12 leaf systems and all the logical connections.

At this point you can detail the parts, create the manufacturing parts, add design seams to the bulkhead, and place edge reinforcement on the free edges of the sketched boundaries. You can also modify the sketched boundaries to have round corners:
