1. OBJECTIVE
This experiment aims to demonstrate the relevance of the virtual laboratory, with its characteristics and utilities, for learning geometric drawing and descriptive geometry, especially in relation to the representation of objects in three-dimensional shapes. The practice carried out streamlines teaching and learning, making it more meaningful in relation to the geometric construction of objects and parts.


At the end of this experiment, you should be able to:

identify the nomenclatures used for projection;

check the difference between conical system and cylindrical system;

build the Mongoan system and the Épura;

define distance, elevation and abscissa;

project a point on the epura and give its location.

2. WHERE TO USE THESE CONCEPTS?
Épura is widely used in architecture and engineering, as it is extremely relevant for detailing everything about an object or piece. It is present in technical representations of electrical, sanitary, architectural projects and in everything that needs to be built to certain standards. It is a form of representation rich in details, which allows you to better understand a specific object or piece, analyzing it in a three-dimensional way. The study of épura applies to the most diverse areas of knowledge, such as geometry, trigonometry, civil construction, among others. This knowledge began with Gaspard Monge, an 18th century French mathematician, who created a method that was based on the representation of three-dimensional shapes in two-dimensional planes through projections. Today, épura remains a major contribution to descriptive geometry.


3. THE EXPERIMENT
In this experiment, you will carry out practice using the Mongoan projection system, recognizing the elements that compose it, in addition to revisiting the theoretical concepts studied. Furthermore, you will see how to obtain épura by rotating the horizontal plane to the point where it meets the vertical plane. With the interactions carried out through the manipulation of the available elements, you will be able to make connections with the definitions, concepts and technical standards studied, as well as formulate observations and conclusions regarding the constructed elements.


4. SCENARIO
The environment for this experiment will take place on a computer with internet access, through software available in the virtual laboratory, which will serve as a resource to support the teaching of geometric drawing and descriptive geometry. Students will interact with the tools available to carry out various activities, with the advantage of fixing the content through visualization of the tools, establishing a relationship between theory and practice.
