This article makes a comparative study of two types of methods used in building construction. On one hand, the creation of drawings uses direct method, basically by measuring and sketching without instruments and, on the other hand, the creation of these plans by modern laser scanning. The aim is to analyze the accuracy of final results and to consider the technical and other resources needed to carry out each method. Two different works, concerning the same building are compared. More specifically works consist of plan views and section views from a project executed and a scanning with laser technology performed of some parts of the same building. From there we will take out the appropriate cross-section slices to get the information needed to make plan and section views. The outcome will be to get information on the level of accuracy and to assess the technical effort required in each case.
