I am trying to replicate this kind of drawing, do you know what’s the easiest way to do it?
Modeling wise or graphically?
Graphically I would start with an orthographic/axon camera, pen or technical display mode in your viewport and then play around with the lineweights and shadow settings.
This may help:

yes graphically! I’ll have a look, do you think that by twisting some setting I can have those nice sharp shadows ?
Yes, for sure!
