General description A Xeometría Descritiva ten como obxectivo a racionalización xeométrica dos temas espaciais. No ámbito académico achega o aparello básico sobre o que se apoiarán disciplinas gráficas máis especializadas como Expresión Gráfica Arquitectónica, Topografía e Proxectos Técnicos, así como o emprego do Deseño Asistido por Computador e a Informática Gráfica. Convértese así na "gramática" da linguaxe gráfica, sendo necesario o seu coñecemento para poder expresarse con corrección e eficacia.

Outra das achegas importantes á formación do Arquitecto Técnico é a súa contribución á configuración e racionalización dun modelo mental da realidade, o que comunmente se denomina "ver no espazo", aínda que sería máis exacta a expresión "imaxinar no espazo".

No ámbito profesional a lectura e interpretación de planos é unha das tarefas necesarias á hora de executar un proxecto de edificación, tendo que extraer dos documentos gráficos toda a información necesaria para a correcta execución da obra. Iso comporta un coñecemento da metodoloxía da representación, cuxa base é a Xeometría Descritiva.

No campo da redacción de proxectos técnicos a Xeometría Descritiva achega a formación da visión espacial necesaria para a xénese da solución final que será tridimensional e dentro da función comunicativa da linguaxe gráfica a través de planos e esbozos, achega o substrato teórico básico dos distintos Sistemas de Representación.

Como materia que utiliza como medio de expresión a súa base gráfica e achega ao debuxo o rigor xeométrico que precisa, fai que esta disciplina sexa imprescindible na titulación de Grao en Arquitectura Técnica, para fornecer ao alumno os coñecementos necesarios que lle permitan desenvolver a súa capacidade creativa e imaxinativa, á vez que está clara a súa achega á práctica profesional, en canto á representación, resolución e restitución de calquera espazo ou elemento xeométrico tridimensional propio do ámbito da edificación.

Assessment comments

There will be three objective exams during the semester.These will contain similar exercises as the ones that are solved in class and will be used to maintain a continuous evaluation process.

The first test will cover Blocks I and II (Diedral System), the second, Blocks III and IV (Diedral System) and the third V and VI (Figured Plans System-Topographical Representation).

It is considered mandatory to attend both lectures and interactive and the students must meet certain minimum requirements for assistance to be able to do the tests. This assistance is established as a minimum of 80%.

The objective three tests will be graded out of 10 points each. The final overall grade of these tests are determined by adding the scores of each one and divided by three. The minimun grade must be 5 in each test so the average can be done.

In addition to attendance, participation and completion of supervised projects, tests may be required in order to properly assess the degree of assimilation of conceptual and procedural course content.

The student will pass the course once the global average score is equal or greater than 5.

Students who do not achieve the minimum score of 5 points will have to attend the oficial final exam for the course that will be held at the end of the semester (First Chance) according to the official calendar approved by School Board.

It will keep the passed test objective scoring but for complete systems. This condition is linked to the current academic year and therefore these passing grades will be saved for the First Chance exam (January) and Second Chance exam (July) but only during the current course and not for the following academic year.

The grading of the final exam and of the different tests , as well as the possible revision of the grade, will be done by the course teacher responsible for the group to which the student belongs.

IMPORTANT NOTE. So that students can get a passing score on the final exams, it is mandatory to score in both exercises for the dihedral system and Topographical Projection (Planos Acotados System). A score of 0 in any of them would lead to the failing grade in the course.

Other comments

By addressing the basics of graphical representation, it is recommended to study the subject of Descriptive Geometry prior or simultaneous to other subjects in the area of Architectural Graphic Expression.

Prerequisites. It is recommended to have studied the subject of Technical Drawing in high school or equivalent training as it is considered that the student must be accustomed to using conventional instruments of graphical representation. They also should know the most basic aspects of the different systems of representation, especially Diedric System  and  basic flat geometry layouts (polygons, conic sections, elementary trigonometry, etc.).
