As I told many many times before:

Take a look to the Part you are about to design. Identify main bodies with a simple shape. Start simple like you would sketch it.

Here is an oversimplified picture what I and most experienced CAD-User see.

So first main bodies
second symmetry of shapes
cuts
and so on

This is part should be easy to do with CATIA, or almost any other 3D CAD system. At first glance it might look complex, but it's really made up with many very simple features. Start with the C-shaped extrusion in the center, and then add each little feature, one at a time, until you have the complete part. (not sure if all the dimensions are there - the drawing doesn't show Section A-A)

Attach a picture of what you've been able to do yourself. And ask questions about specific areas that you need help with.
