General description A Xeometría Descritiva concíbese como soporte da linguaxe gráfica, posibilitando o uso do debuxo como expresión e representación do espazo arquitectónico.

Achega rigor xeométrico á representación e análise da arquitectura e desenvolve a capacidade de imaxinación e lectura espacial.

Development of the capacity for imagining and reading spatially, so that the student can imagine in the space an object represented in the plane, and he can represent in the plane what he previously imagined in the space, that is to say, stimulate the spatial apprehension or "see in the space". A10

Methodologies Description
Objective test A final test will be done to all those students who in spite of attending the course did not pass the subject. It may consist of theoretical and practical content.

Personalized attention
Methodologies
Objective test
Description
The subject is conceived eminently experimental and practical as the student's learning process is based on the realization of graphic exercises that enable the student to participate in a more personalized relationship with the teacher.
Exercises will be developed individually or in small groups and will be related to course work.
In order to achieve the objectives set, tutorial attendance scheduled by the tutor is considered essential.

FIRST OPPORTUNITY (JANUARY)
Applying to students either scoring below 5 or with average special exercises below 5 and observing the following conditions:
- 80% attendance and submission of all weekly exercises
- Delivery of the supervised projects

SECOND CHANCE (JULY)
The same conditions as the first opportunity. The score of the objective test to pass the subject will be of 5. That score will stand for 30% of the final grade.

Assessment comments

In order to pass the subject on the 1st and/or 2nd opportunity it is a compulsory requirement that students have completed all course work and exercises.

STUDENTS WITH REGISTRATION AFTER THE START OF THE ACADEMIC YEAR (September): Taking the first opportunity will be allowed. 80% of attendance shall be counted from the date of enrollment, and previous works required for the final evaluation will be rescheduled.
