Creating a Bulkhead

This task explains creation of a bulkhead. In the example below a transversal bulkhead will be created. The process is the same for creating a longitudinal bulkhead.

1. Create an SFD system under the tertiary system (see Organizing Your Document), rename it if necessary. Select the CATPart that is created under the system in the specifications tree and go Start - Equipment & Systems - Structure Discipline - Structure Functional Object Design.  The image below shows finished transversal bulkheads, along with the specifications tree structure.



Click the Plate button to display the Plate dialog box. The entries are explained below:

  3. CATEGORY: Click on the down arrow to display the entries - they will include the last 10 entries that you selected. If Transverse Bulkhead is not displayed then select More to display the Class Browser and make your selection from that list.
  4. NAME: The application can assign a name to the object you are creating using the object naming function if you check the Automatic checkbox. If you want to assign your own name then uncheck the box and enter a name.
  5. SUPPORT: Select a cross as the location for the bulkhead -  once you select a cross the bulkhead is placed (in preview mode). Your selection displays in the Support field. The image below shows the bulkhead in preview.

  6. LIMITS: This function trims the excess plate.

To do this, select under Limits, and select the objects you want to use to limit the bulkhead. (In this example, shell, upper and lower deck, and a longitudinal bulkhead.)

The plate is trimmed, and the Object field displays the objects you selected.

The image below shows the trimmed bulkhead.

Under Offset, you can define the offset value of each plate limit. A positive value adds material. A negative value removes material. Additionally, limit tags display in your 3-D session to assist with plate limit management.

The Remove button allows you to delete a limit.

The Switch Side button lets you toggle between limited sides. You can also switch sides by selecting the same limit again.

  7. To place more than one bulkhead, select the Support field again and select your supports, in this case the planes. The bulkheads will be defined with the same limits used in placing the first bulkhead.

  8. Click OK when you have finished.
