|This task explains creation of a face plate stiffener.|
"free edge'' is the end of a plate that is not limited by another object.
This could be a deck that does not run the entire length of the ship, in
which case the edge that is not limited by the hull is considered free
edge. Or it could be openings in the deck, the edges of the openings being
free edges. Web girders also have free edges. Stiffeners are often placed
on these free edges to strengthen them. The image below shows a face plate
stiffener placed on a web girder.
document open click the Stiffener on Free Edge button
to open the
Stiffener on Free Edge dialog box.
If you select the plate on which you want to place the stiffener before you open the dialog box it will be pre-selected. You can change the selection by clicking in the Plate field and selecting a plate in the specifications tree, or in the viewer. As soon as a plate is selected the free edges in it highlight and can be selected. When you move your mouse pointer over an edge it changes color to green. The image below shows the free edge of a web girder after a mouse pointer has moved over it.
|2.||CATEGORY: Select a category by clicking the down arrow in the Category field, in this case face plate.|
|3.||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.|
field displays the free edges that have been selected. You can select more
than one edge, and view them in this field.
The Entire Limit checkbox allows you to place stiffeners along all joined free edges, if they were defined with a sketch.
In the web girder shown above, the free edge has been defined using a sketch, and consists of three sketch elements. If you select the Entire Limit checkbox the stiffener will be placed on the entire edge. If you uncheck the option, the stiffener will be placed only on the element you select. In the image below, the Entire Limit checkbox is not selected, and the mouse pointer has been moved over the web girder. The stiffener will place on the green portion only.
You should note the following behavior:
When the Entire Limit checkbox is not selected, stiffeners placed on all contiguous edges will be combined into one. Initially they will display separately in the specifications tree, but will be combined once you click the OK button. This will happen if they were defined using the same process. If in the same document you have free edges that were defined using a sketch, and others that were defined using a non-sketch method, then:
|5.||Click the button next to the Edge field to display the Elements List. You can use the list to delete or replace stiffeners that you have added. To replace, select the free edge, click the Replace button, then select the new free edge.|
default, stiffeners are placed from end to end of the free edge you
selected. If you need to resize a stiffener, you have to define the
Under Limits, in the Name field, select Start and select a starting limit. You can select a plane, plate, another stiffener or a surface. The stiffener is limited as soon as you make your selection.
Use the same method to define the End.
Under Offset, you can define the offset value of each stiffener on free edge limit.
|7.||WEB ANGLE: By default the web of a stiffener is placed perpendicular to the plate. If you want to place it at an angle then enter the preferred angle in this field, or use the Up/Down arrows.|
|8.||Anchor point offset: This allows you to modify the location of the anchor point of a face plate stiffener. As an example, a stiffener with a center-right anchor point, and 0 mm offset, is positioned equally to either side of the plate. Changing the offset value moves the stiffener more to one side or the other. See Defining Orientation for more information.|
