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 the Topographical Drawing in Engineering problems, including the design of roads and dams, involving calculation of volumes of excavations, embankments and dams.

Working method

Presencial

Program

Technical Drawing: Sizes of design sheets. Types of lines. Projection systems – conic, parallel and orthographic. Views. Disposition of views. Fundamental views. Primary and secondary auxiliary views. Cuts and sections. Indication and disposition of cuts and sections. Partial cuts. Rotation of cut planes.

Architecture Drawing: Site, global and detail drawings. Plans. Elevations. Sections. Symbolic representation: doors and windows; sanitary equipment and other permanent equipment; stairs; furniture; revetment of surfaces. Dimensioning of plans and sections.

Application of Computer Aided Drawing in the scope of Technical Drawing and Architectural Drawing.

Elevation Method: Point, line, plane. Union. Intersection. Perpendicularity. Metric problems. Applications. Roof plans. Shadows: parallel light; conic light.

Topographic surfaces: Definition. Contour lines. Scales. Equidistance. Intersection with planes and lines. Profiles. Maximum inclination lines. Equal inclination lines. Applications. Stretches of roads – plan drawing; areas occupied by fill and excavation slopes; longitudinal and transversal profiles; fill and excavation volumes. Dams – plan drawing; reservoir volumes.

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.

Evaluation Type

Distributed evaluation without final exam

Eligibility for exams

Achieving final classification requires compliance with attendance at the course unit, according to the L.EC assessment rules. It is considered that students meet the attendance requirements if, having been regularly enrolled, the number of absences of 25% for presential classes is not exceeded.

Calculation formula of final grade

Distributed evaluation - two written tests, without consultation, and an optional work on Computer Aided Drawing (Autocad), carried out outside of classes. The final grade (NF) is given by the following equation:

NF= Maximum ((0.44*T1+0.44*T2+0.12*TA); (0.50*T1+0.50*T2))

where: T1 - classification in test 1; T2 - classification in test 2; TA - classification in Autocad work.

The maximum final grade obtained by the above equation is limited to 18 (0-20 scale). In order to obtain a higher grade, the student needs to reach a grade higher than 18,5 in the two tests (0.50*T1+0.50*T2) and do an extra test.

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.
