I learnt in architecture school, that one way of preserving cultural heritage such as buildings that there are no drawings of, is to measure them precisely and make the drawings using those measurements. This way, basically if the houses burned, they could be rebuilt using the drawings. 

These are 1:1 drawings of a classic park bench. So in case there comes a day we no more remember how they we're like, we can rebuild some.

Here's how its used :)
