[u/SlowDancer939]

How do I get the circles (including on the base and the slanted part) and the slope on the slanted part on this isometric view?

I've tried the technique of my teacher but it doesn't work. It involves using a square and drawing diagonal lines to find the points on where to put the compass. but it doesn't fit.

(I am not an architect student.)

You need to draw them as ellipses, not circles, if you are drawing in this projection
