1. The problem statement, all variables and given/known data
Draw the third view and the points on each view. In the first picture you have what the exercise has given us and in the second what I have drawn. I have turned the page so that the first view is the one on the left, the horizontal one is the one on the right. Is that OK? Should I use the one at the right as a lateral view?

2. Relevant equations

3. The attempt at a solution

The view from the right (using the orientation in your sketch) is a bit more interesting, but it looks similar to the one from the left.

I would expect b and a to be at a different height (again, in your sketch), but I'm not sure if I interpret the pictures correctly.

Why did you rotate the pictures?

I rotated the pictures before uploading so that they would seem the same as they are in reality. (While photographing them they rotated in the wrong direction.) I don't know if I did it right to put the view on the right at the exercise as the vertical view. Should it be lateral? Where should b and c be?

It is just confusing with the relative rotation.
Unless the ' and '' have some meaning I'm not aware of (=not just indicating which type of view they are drawn on), are those points not at the first visible surface?

The drawing is easier to read if you minimize hidden lines, so I'd move the third view to the opposite side.

Note you are using first angle projection here, which is common in Europe. (The U.S. uses third angle projection.)

Keep the line thickness and line weight of the circle the same as the straight lines.
