Objectives

JUSTIFICATION AND OBJECTIVES:
Identifying and defining three-dimensional geometric shapes and their representation on the plane. Application of «languages» of graphical representation used in Engineering – the Technical Drawing, the Elevation Method (one-orthographic projection plane system) and the Topographic Drawing. The importance of the Technical Drawing as «professional language» associated to the conception, execution and interpretation of the engineering drawings.

Learning outcomes and competences

LEARNING OUTCOMES:
- Interpret and define geometric shapes in three dimensions and their representation in the plan;
- Perform and interpret perspectives, views and cuts/sections of objects;
- Acquire knowledge on architectural design;
- Solving practical problems using the studied methods;
- Use Drawing in Engineering problems, including the design of roads and dams, involving calculation of volumes of excavations, embankments and dams.

DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES:
The execution and interpretation of the project drawings require, on one hand, skills related to the interpretation and definition of the three-dimensional geometric shapes and their representation on the plane and, on the other hand, knowledge of the graphical representation "languages" used in engineering.

Teaching methods and learning activities

Gradual explanation of the discipline’s matters and resolution of problems.

DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
The introduction of techniques and problems with increasing difficulty allows, in an early stage, to overcome basic weaknesses that some students have and, gradually, absorb the knowledge of Technical Drawing.

Eligibility for exams

Approval of the course unit implies compliance with the attendance requirement, considering that a student complies with this requirement if, having been regularly enrolled, they do not exceed the limit of 25% of absences from the face-to-face classes scheduled for each type. In addition to the cases provided for in the FEUP rules in force, students who have obtained a final grade of 6 or higher in the course in the immediately preceding academic year are exempt from the attendance requirement.

Calculation formula of final grade

Distributed evaluation - two written tests, without consultation, and a work on BIM modeling. The final grade (NF) is given by the following equation:

NF= (0,45*T1+0,45*T2+0,10*TP)

where: T1 - classification in test 1; T2 - classification in test 2; TP - classification in BIM modeling work.

Special assessment (TE, DA, ...)

The total classification of the written tests (T1 and T2) is  replaceable by that of an exam during the appropriate examination period (T). The TP component is replaceable by an assignment with the same scope, to be indicated by the teacher, that should be completed before the date of the exam.

NF= (0,90*T+0,10*TP)

T - Classificação no teste;
TP - Classificação em trabalho prático a indicar pelo docente, e a entregar até à data do exame

Classification improvement

There is also a recuperation test, to get improvement of classification, where students can opt to be evaluated only on the matter concerning one of the tests or on the whole program.

Component TP is the result of the work carried out during the semester and its classification cannot be improved.

Observations

During any assessment, the possession of any electronic device (e.g. mobile phones, tablets, headphones, smartwatches, etc.) is strictly prohibited, with the exception of those expressly indicated by the teaching staff (e.g. calculators).
It is the student's responsibility to anticipate this situation before the start of the assessment.
