Creating Air Inlet-Outlet Louver in NX

You can create an Air Inlet-Outlet Louver feature in the NX Sheet Metal application as shown in the figure.

To create a Louver:

1. Draw a single line on the planar sheet metal face.
2. Start the “Louver” command.
   Home Ribbon Bar => Punch Group => “Louver”
3. Select the single line created in step 1.
   
4. Set the Depth and Width values in the “Louver Properties” group.
   Note: You can also arrange these settings by dragging the arrowheads in the graphics window.
5. Set the louver type
   1. Lanced: Louver ends are open.
   2. Formed: Louver ends are close.
6. If you want to blend Louver edges.
   1. Open the “Settings” group in the dialog box.
      Note: If you can not see the settings group in the dialog box, click on the drop-down arrow under the dialog to open the settings group.
   2. Turn on the checkbox near the “Blend Louver Edges”
   3. Type a new radius value in the “Die Radius” box.
7. The louver preview will be seen in the dialog box.
8. Click on the “Ok” button to create Louver and exit from the command.

Note: You can create only one louver at once. To create a louver group, use the pattern command currently hidden in the Sheet metal application.

To create a Louver pattern

1. Start the “Pattern Feature” command.
2. Select the Louver created.
3. Set the “Pattern Definition” (Spacing method, Count, Pitch Distance, etc..)
4. Important: Change the “Pattern Method” to “Variational”.
   
5. Click “Ok” in the dialog box or click twice on the middle mouse button to create a pattern.
