graphically represent an aeration duct

[Davimont]

to draw sections of aeration channels taught me years ago to represent them in this way

I don't work in the construction industry but it happens to draw these channels for air treatment machines.
Is it a proper way to draw the channels? Is there a norm describing this depiction?
thank you to those who want to answer me.

I don't remember why

We also represent in that way both squares and circular in the concrete foundation designs of the plants.
You should consult the architect's manual that I know there are also indicated there in that way. the prospective blackness from the idea of depth and if it were represented only with the outer edge would be confused with a well rather than with a geometry of cement.

ok thank you, as I already wait for the usual turn that will come to me to ask, at least I will be able to answer it is correct. Even if I quote him a norm he wouldn't even know if it's food!
