Here is a demonstration showing you the design of a simple grid in CATIA 3DExperience.

The Sheet Metal Design application, based on industry process features, allows you to create quickly a plate that you can bend and add stamps, dowels, bridges, etc.
In this video you will see how to use the Louver feature that allows you to design a grid in only 5 min!

1. Step 1: Video

   
   

2. Step 2: Create a plate

   Open the Sheet Metal Design application

   * the 3Dpart panel appears *

   Create a 3Dpart called "Grid"

   -

   click on the global parameters

   set the thickness to 0,3mm

   set the radius to 1mm

   * this will apply for all the features of your design *

   -

   Draw a centered rectangle 400*250mm

   Exit the sketch

   Create a wall with the profile

   * the thickness is automatically set up to 0,3mm *

   
   

3. Step 3: Add holes to corners

   Edit the sketch

   Add R20mm fillets on the for corner

   Select the centers of the fillets

   Click on output feature

   * in that way, the points will be shown when you exit the sketch *

   

   * The points should be visible *

   -

   Create a hole Ø15mm using the point

   * if the hole is not centered with the point, edit the sketch and add a coincidence between the 2 points *

   Do the same with the 3 other holes

   * tips: select the point first, then the plane or surface *

   

   * The result should be this one *

   
   

   
   

4. Step 4: Create the Louver

   Create a sketch on the plate's surface

   Draw a centered rectangle 325x15mm and 110mm from center of the sketch

   * like this *

   

   -

   Use the louver with the rectangle profile

   Select the opening edge (bottom line)

   Set 5mm in height

   Angle a1 45deg

   Angle a2 80deg

   

   Click on OK

   

   * The result should be this one *

   
   

   
   

   
   

   
   

5. Step 5: Pattern the Louver

   Go transform tab on the action bar

   click on rectangular pattern

   * select instances and length type *

   Instances 10

   length 220mm

   * be sure that the direction is vertical *

   

   * here is the result you should obtain *

   
   

   
   

6. Step 6: Refine the louver

   Edit the sketch of the louver feature

   Add fillets R7,5mm on the top corners

   

   Exit the sketch

   * the part will be automatically updated *
