By measuring all dimensions of the structure; having a plan, side view and cross section; with the other words re-scaling the structure. This technic is important for restoration and evaluation of architectural history. Also, we can say that survey drawing shows the existing situation of a structure.
This scaled technic drawing gives us the indoor and outdoor information structure. Especially information about its construction and structural composition.
For making a survey, architects should have detail measurement and information about the structure. For having these kin of information, we should take photos of structure and mark the direction on it. Furthermore, we should look at, if there is, old drawings. and we have to make sure having all details of structure in itself and if it is important according to the other built or natural environment.
