Creating a Deck

This task explains creation of a deck.  
In most cases one entire deck or bulkhead will consist of one plate. However, in some instances you may want a deck or bulkhead to consist of more than one plate.



1. Create an SFD system under the Primary Systems product (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 Detail Object Design.  The image below shows the specifications tree structure and the completed deck.



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 Deck 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 an appropriate support for the deck -  once you select a support the deck is placed. Usually the support is one of the planes (grid), though you can select a surface also. Your selection displays in the Support field. NOTE: For a deck, the slope should not be more than 45 degrees. You will get an error message if you exceed these limits. You will also note that the plate exceeds the outlines of the hull. This 'excess' is defined by the bounding box created by your administrator. You will need to 'trim' it, as explained in Step 7 below.

You can also select a support by displaying the Plane Systems dialog box. Right click on the Support field to display the Plane Systems dialog box. Select a system or sub-system by clicking on the arrow, and then select a plane, or you can key in the plane in the Key in Planes field.

You can select which side of the support you want the plate thickness applied. The default will be as decided by your administrator. If you want to override the convention then click on the arrow that is displayed. The plate will be placed differently from the default and the arrow will turn red. You can click again to toggle it back.

Click the button next to the Support field to display the Elements List. You can use the list to delete or replace supports that you have added. To replace, select the support, click the Replace button, then select the new support.

  6. OFFSET: Enter a value in the Offset field if you need it. This is the value by which the deck will be offset from the support you selected. The value is expressed in the units selected in your workbench. Enter a negative (-) sign in front of the value to offset it in the opposite direction.
  7. LIMITS: This function trims the excess plate. You should select the shells to indicate a limit for your plate.

To limit the plate, click under Limits, and select the object you want to use to indicate the limit. The plate is trimmed, and the selected object displays under Object.

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. In the images below the user is clicking the Switch Sides button to toggle limited plates. You can also switch sides by selecting the same limit again.

  8. Click OK when you have finished.
