Creating an Opening with a Standard Opening

This task explains how to create an opening with a standard opening. 

With your 3-D session open, click the Opening button to display the Opening dialog box.



Select from the Category drop down list.

The name of the opening is assigned automatically, using the object naming rules. If you want to assign your own name to the opening, uncheck the Automatic box and enter a name.

  3. In your 3-D session, select the objects (plates, stiffeners). The Applied To field shows the objects to which the openings will be applied.

When you select more than one object, the selected number of objects display as elements in Applied To field.

  4. You can remove and replace objects that you select.

Click the button beside the Applied To field and the Elements List displays, listing the objects you selected.

Select an object on the list that you want to replace, and click the Replace button. Select an object in the 3-D session, and this object displays on the Elements List in place of the original one.

You can also remove objects from the list. Select the objects you want to remove, and click the Remove button. The selected objects are removed from the Elements List.

Click Close when you have made all the necessary changes.

  5. In the Method field, select Standard for a standard opening.
  6. Select the Standard Opening Definition button and the Standard Opening dialog box displays.

  7. Select Contour and Position from the drop down lists.

Contour is the shape of the opening.

Position is the strategy used to determine where an opening is placed. An image of the opening reflecting the selected position strategy displays in the dialog box.

By entering references for the U and V directions, you can create multiple openings at specified positions. See explanation of the References pane below.

  8. When you select the Preview checkbox, you can preview the openings in your 3-D session.
  Use the Position tab to define the position of the openings.

In the Parameters pane, change the angle of the contour under Value as necessary.

  10. In the References pane, select the U and V rows, and select a 3-D reference object (plane or plate) to define the position of the opening. You can also right-click and select Select Reference Plane from the drop down list.

Information listed in the References pane depends on the Position selected.

NOTE: You can multi-select references in the U direction and create multiple openings. (The Elements List displays whenever you can multi-select, listing your selections.) You can only select one V direction except for Mid-Dist/Mid-Dist.

Offset/Offset - Offset from reference elements in U and V directions.

Half-Height /Offset - Offset from a reference element for U, then position in V halfway between plate edges.

Mid-Dist/Offset - Position halfway between two elements for U, and offset from another reference element for V.

Mid-Dist/Mid-Dist - Position halfway between two elements in U, and halfway between two other elements in V.

Half-Height/Mid-Dist - Position halfway between two elements in U, then position in V halfway between plate edges.

  11. You can select Chain for references in the U direction only for the three Mid-Dist positions.

When Chain is not selected, you position openings between each pair of references (for example, between 1 and 2, 3 and 4, 5 and 6.

Selecting Chain allows you to position openings between every reference (for example, between 1 and 2, 2 and 3, 3 and 4, 4 and 5, 5 and 6.

  12. Change Offset values as necessary. The offset is in the direction of the Side value. This value depends on the reference object selected.

You can click the Switch Side button to change the direction from the reference object where the opening will be placed.

  Use the Contour tab to select the contour parameters of an opening.
  13. On the Contour tab, an image displays the current contour parameters.

Select a row and change the dimensions of the contour (under Value) as necessary.

NOTE: You can only change the parameter values if the Status is Unlocked.


Your 3-D session displays the changed values when the Preview checkbox is selected.

  14. Click OK when you have created the required openings.
    The following displays openings when a Mid-Dist/Offset position strategy is used. Three pairs of references in the U direction are selected to create multiple openings. (Chain is not selected.)

  You can double-click an opening in your 3-D session, and edit certain information.

You can modify information only for the selected opening (you cannot multi-select).

You cannot change the position strategy of the opening.
