It's a learning process. You just have to keep practicing and eventually you will get to the point where you can look at a drawing and visualize in your head how to start and how to create the 3D model.

It's not exactly what I would call common practice nowadays. Small components like this are likely better suited for inventor or solidworks than autocad, specifically. I've done 1 set of projections like this before in Autocad with a custom view, display style and dimensions. I designed a pole barn in 2008 for strykers and showed projections of each steel saddle alongside the details. But only because I had already modeled the entire project in 3D and it made sense at the time. I had to create a custom display style for it to display correctly. Also wanted it to look impressive for the client. Might still have that somewhere. -ChriS

Oblique and cabinet projections were a common way of making pictorial drawings for engineering graphics books more than 50 years ago. I agree, they can be confusing. It is a bit disheartening to see them used in 2020 for CAD course exercises.
