What is 2d Models

Chapter 3
Analysis, Conservation, and Restoration of Tangible and Intangible Cultural Heritage
Procedure for the communication of knowledge of the built environment and multidimensional elements based on schematization that leads to a reduction in the number of dimensions from three to two and that materialize on two-dimensional supports. Drawings that are conventionally represented elements of architectural and archaeological nature at different scales of representation, consisting of plans, elevations and sections. In order to communicate all the knowledge acquired about the surveyed object, two types of models can be made: geometric models and textured models. The first typology of model is characterized by the geometrization of the elements represented and show the morphology and the spatiality of the object; the other one makes explicit the actual configuration of the elements and shows graphic characterization indicating the quality of the surfaces and their state of preservation.

Abstract
This project's principal intention is developing a structure from a motion thematic applied to an architecture field in both medium and large scale, in order to generate a cloud of points. These are obtained thanks to photographic footage, which can later be used during the H-BIM process. The matter of 3D digitalization is a very current issue for many countries including Cuba. The growth of such a technological application for tridimensional restitution of historical buildings is treated by giving special attention to those belonging to Havana's architectural and cultural heritage.

Chapter 6
Built and Destroyed Memory: Where Does Methodology Lead?
The end product of the projection and section of a 3D geometric model. They are the drawings conventionally used to represent built elements at different scales. As a result, perspectives, axonometric projections, topographic projections and orthogonal projections are 2D models. However, survey uses two kinds of 2D models: geometric 2D models and architectural 2D models. The former are characterized by the geometrization of the represented elements and indicate its morphology, the spatiality of the architectural object, the actual surveyed data and sometimes the method adopted (direct, topographic, etc.). Instead the latter provide the configuration of the elements interpreted by the surveyor and through graphic characterization express the quality of the surfaces and their state of conservation.
