I believe the answer is:

tier

I'm a little stuck... Click here to teach me more about this clue!

This could be a double definition.

'one drawing' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'level?' is the second definition.
(I know that level can be written as tier)

Can you help me to learn more?

(Other definitions for tier that I've seen before include "this person secures" , "He might do sailor's knots" , "Wedding cake feature" , "Person joining" , "One securing" .)

I've seen this clue in The Guardian.
