The Technical Drawing course is part of the 2nd year - 1st semester of the CTeSP in Industrial Management. It is a curricular unit in the area of Engineering Sciences that aims to provide structuring knowledge in the area of standardised graphic representation and interpretation of orthogonal projections that are essential for interpreting two-dimensional, 2D and three-dimensional, 3D drawings. Objectives and expected learning outcomes Ob1: To assimilate the basic rules for communicating an object or product through technical drawing; Ob2: Learn about computer-aided design (CAD) systems and develop technical drawings using computerised means; Ob3: Visualise the object or product in three dimensions, developing its planning in two dimensions. Ob4: In this curricular unit it will be important to know the rules for the technical representation of a part for subsequent industrial distribution with a view to its manufacture. The aim of this course is also to master two-dimensional computer-aided design (CAD). Three-dimensional modelling will be briefly introduced, but the development of computer modelling tools will be left to later courses in the curriculum.
Skills to be developed Knowledge, understanding and execution of drawing: - Representation in orthographic projection, including nominal dimensioning, of isolated parts applying the concepts and methods of technical drawing. - Interpreting orthographic and perspective drawings of individual parts and assemblies. - Isometric axonometric perspective representations of individual parts and assemblies. - Ability to produce two-dimensional, 2D and three-dimensional, 3D drawings using computerised means, CAD software.

Demonstration of the syllabus coherence with the curricular unit's learning objectives
This curricular unit will teach content that will enable students to acquire the knowledge and skills to:
1. Represent isolated parts in orthographic projection, with the respective nominal dimensioning, applying the concepts and methods of technical drawing. 2. Interpret drawings of isolated parts and assemblies in orthographic representation and execute the corresponding representations in isometric axonometric perspective. 3. Identify common standardised mechanical components and understand their function.

Learning Methods
Theoretical and theoretical-practical presentation of the subjects using the expository and interrogative method followed by a presentation of the more practical side of the subject using the demonstrative method.
Training activities, using the active method, are based on proposing exercises to the students which must be carried out as independently as possible and consist of representing parts and assemblies in freehand sketches.

Continuous Assessment
Written test I: 35%
Written test II: 35% Group work: 30% Work must be submitted via the ELearning platform in accordance with the final dates defined in the PIA.
In accordance with the General Regulations: a) Students' actual attendance at classes will be recorded and, if the number of absences per student exceeds 30 per cent of the total number of contact sessions planned for each course unit, they will automatically be transferred to the final assessment of the normal term; b) A minimum mark of 7.5 is required in the written tests and in the defined assessment elements; c) If the student fails or obtains a mark lower than 7.5 in the tests or assessment elements referred to in the previous paragraph, they will automatically be transferred to the final assessment of the normal period; d) If the student fails or obtains a mark of less than 7.5 in the second written test (taken on the same date as the final written test of the normal period), he/she may apply for enrolment for assessment in the appeal period; e) All written academic work included in the assessment (worksheets, drawings, etc.) must be submitted on the ISAG E-Learning platform by the deadline.

Demonstration of the coherence between the teaching methodologies and the learning outcomes
The method used during lessons to introduce concepts, associating these concepts with answers to a real-world problem, will enable students to acquire the knowledge and understanding necessary to achieve the objectives Ob1.
The approaches in the more practical component of the lessons are based on developing autonomy in the practical application of the concepts covered, thus allowing the more theoretical concepts of objective OB1 to be consolidated and the more practical objectives, Ob2, Ob3 and Ob4, to be fulfilled. The fulfilment of objectives Ob3 and Ob4 is further reinforced through the interconnection between the two inverse processes of orthogonal projection/perspective representation, which will develop the ability to use visualisation (mental, on paper or by computer means) of a perspective to transpose it into projections, a typical path in the design process, or the reverse, the ability to use a projection to interpret it into a perspective.
