 Turn OFF the visibility for Deck4Planes
 Go Bulkheads in Tier4
 Press Pick Traces button and start selecting all bulkheads traces in the Deck3 selection
rectangle. Press Enter when done and the trace list will be populated:
 Fill in the Limits:
 Copy all the stiffeners definition from LongBulks.onDk2 and paste them to

17.b Creating the A-deck (Deck5) and the bulkheads underneath:
 In similar fashion as for Deck4Plane1, create the Deck5Plane at 17.2 m, with the same
stiffener and opening definitions as Deck4Plane1, and with the limits as below:
128
 Apply to
Deck5Plane and obtain:
 Create the Bulkheads in the same way as for Tier4, the preparation is not required
anymore, as no bulkhead touches the shell this time. The selected bulkheads from Deck4
rectangle will be:
