To be honnest, this is not the most difficult part to draw.
Just a plain piece of "mechanical engineering"
I'm not experienced in catia, I work with SW and this model is "quite" simple.
It only will take you some time and effort, to me this is what 3D engineering is fun. Just start working on it and you will see it is an "easy" job, no difficult planes or shapes, just the basics of drawing....
