  • Learning outcomes of the curricular unit:


    The objectives of Computer Aided Drawing (CAD) are to provide the adequate knowledge on the usage of a computerized tool that will enable students to produce 2D and 3D drawings. This useful knowledge will allow students to improve their performance in subjects done later in the course. Optimization of work processes using 3D CAD software are carried out.

    Specific Skills:

    CAD allows its users to develop the creation of 3 dimensional parts by means of a computerized tool and the conversion of 3D models in 2 dimensional drawings, in accordance with the existing technical normative. It also allows the optimization of the workflow. Knowing the principles associated with the establishment of sets of components. Knowing the standardized elements available in the software library. Know the general principles of modeling biomedical devices, namely transforming a 3D part in multiple 2D views.

  • Syllabus:
    1. Introduction to 3D graphical modeling. Commercial software available in the market. 
    2. Graphical 2D AND 3D Transformations: Geometric Transformations and coordinates. Modeling of curved surfaces. Transformation of curves and surfaces. Interpolation techniques and modeling characteristics. 
    3. Construction of 3D solid. Drawing sketches of 2D (2D sketching) components. Relationships between entities. Three-dimensional modeling. Practical applications graphical modeling solids involving biomedical devices.
    4. Modelling of sets of components. Examples of association and parameterization. Exploded Views in 3D. Import of standard components. Applications in biomedical devices.
    5. Production of technical documentation. Examples of association between 3D models and 2D drawings. Applications in biomedical devices.
  • Demonstration of the syllabus coherence with the curricular unit's objectives

    The syllabus presented includes all the issues described in the objectives of the curricular unit.

    Throughout the classes will be given all the necessary content in order to achieve the specific objectives described, particularly as to the best use of CAD software and their correct application.

    In the theoretical-practical classes students will be accompanied throughout their work to ensure the acquisition of the skills required.

    In every class practical exercises, which accompany defined syllabus, successively more demanding, and whose implementation is monitored by the teacher in order to ensure proper acquisition of knowledge required are given.

    During practical classes students will be accompanied throughout their work to ensure the acquisition of the required skills.

  • Teaching methodologies

    Teaching Methodology:

    The teaching methodology is based upon practical exercises. In accordance with the program, the difficulty of the exercises increases during the semester.


    The practical exercises (T1, T2 e T3) and the pedagogically fundamental assignment (TF) are the main assessment elements.


  • Demonstration of the coherence between the teaching methodologies and the learning outcomes.

    Throughout the lectures all necessary contents for the acquisition of theoretical knowledge by the student will be given. This means that all theoretical goals presented will be addressed during this component.

    During practical classes practical works will be analyzed and performed by students under the direct guidance of the teacher, analyzing their structural and technical contents, in accordance with the objectives of the curricular unit.

    Throughout the lectures will be taught all necessary contents for the acquisition of knowledge by the students, ensuring that all theoretical objectives are addressed in the course of this



    In the classes, which are essentially laboratory, varied work of increasing difficulty and complexity will be presented, which will be performed by students under the direct guidance of the teacher, by analyzing the structural and technical content of the same, taking into account achieve the objectives of the course.

    The methodology used in the classes is based on the use of software, video projection screen for monitoring of students.


    At the end of the semester, each student wills individually (or in groups) a small project in which the student must demonstrate knowledge on all matters seized a comprehensive and integrated manner.
