Speaker pattern ?

All of the three patterns in the attached picture are asymmetrical and hand-drawn, so none of them can be exactly patterned in any CAD system.

But something similar to the larger, turtle shell image on the left can be done in CATIA like this:

1. make a Sketch of 1/6 section of the design, using circles, splines, or lines to define each closed shape.

2. Make a Pad from the 1/6 sketch.

3. Mirror the Pad to get 1/3 of the design.

4. Use a Circular Pattern to rotate the 1/3 and get the complete design.

The important lesson to learn here is to not make complex sketches. Keep sketches simple, and pattern the resulting solid features (Pads, Pockets, etc)

speaker grill with uniform holes

If the part requires a pattern of uniform shapes (such as a speaker grill with circular holes):

1. make a single Hole

2. use Rectangular Pattern to create a single row of holes

3. use Circular Pattern to rotate the entire row of holes about the center
