Abstract
Purpose:
Traditional underground cellars are singular elements of Architectonic and Cultural Heritage of Spain. Branched plan, irregular sections and rough surfaces complicate the survey and geometry analysis of these constructions. The purpose of this research is to set a data capture technique that documentsefficiently and accurately the underground Architectonic Heritage.

Avenida Complutense s/n. 28040 Madrid We propose a methodology based on 3D scanner to study and analyze the traditional underground constructions. Thismethodology offers the possibility of a large data acquisition in a short period of time, obtaining a detailed study of the volume of this type of traditional construction, and their distribution in space.

Result:
The 3D scanner shows the structure and the details concerning underground construction, capturing roughness or small shape changes in the walls. 3D scanner accurately distinguishesthe texture of walls and elements of the cellar. Also different materials can be identified. The approximate time needed in each shot is 4 minutes for scanning and 10 minutes for image capture.

Discussion & Conclusion:
We can conclude that the 3D scanner technique efficiently and accurately characterize and represent underground constructions. 3D images have high quality and clarity, enabling toanalyze visual elements (texture, color, lighting and shape).

1 Introduction
1.1 Real object and object representation

1.2

Nature and architecture

In its epistemological process man, through abstraction, reaches the idea of a real object. The drawing and representation allow, as the word, identify and communicate those concepts. In fact, his adaptation to reality is what makes themauthentic, real. His interest is not limited in themselves but what they have reference to the concept or reality. In architecture, for example, the geometry of structural elements becomes a vehicle or tool of communication. The knowledge of the classical world comes from the drawing of the proportions and architecture is created as the embodiment of the proportions in the drawing. EarlyRenaissance writers understood that the plans and the intersections are things necessary. We still teach the artist to stick with his hands what he has learned with his mind” [1]. The ultimate goal of representation is not itself but the reference to reality, either as existing object or object that is created.

Today everyone talks about bioclimatic or ecological architecture but ... What does this mean?Unfortunately on many occasions this term is more than just a false label. ”If we wish to know the truth concerning anything, we will find it in the nature of that thing” [2]. Our study looks at the architecture by analogy with nature: how we know the geometry or abstract from nature, geometry, not merely in metric but with all its accidents: color, texture, inertia, temperature, lighting,...
