2. Objectives and learning outcomes

2.1 Objectives

Establishing and developing students' spatial reasoning ability, acquiring technical drawing what is the expression of communication in technical fields. In the course of the subject students learn four representation systems: perpendicular parallel projection, inclined parallel projection, centric projection and dimensioned representation.

During the semester students get acquainted with the following topics: imaging and reconstruction in Monge's two projection plane imaging systems, representation of space elements in a general and special position, catching, visibility, transformation of field elements, intersection tasks, intersection of solids with plane surfaces into rotation surfaces, levelling, interpenetration of solids with planes and rotation surfaces, shadow editing, line moving generated surfaces which can not be expanded.

Flat surface elements and simple rotating surfaces representation in perpendicular - parallel and oblique - parallel projection systems.

Representation of flat elements and simple rotating surfaces in a central projection system into two or one focus points onto vertical plane.

Basics of technical drawing are aimed at drawing elements, proportions and scales, reduction and enlargement, preparation of floor plan and cross section.

During the semester, students use the knowledge gained in the above listed topics and prepare their homework.

3.3 Evaluation system

3.4 Requirements and validity of signature

Signature cannot be obtained.

3.5 Grading system

HA0, HA1, HA2, PR, A, are rated with a grade between 1 and 5.

The minimum requirement for obtaining a grade is a passed (2) for both parts of the mid-semester test (passed for the descriptive geometry and for the engineering drawing part also), and at least a passed (2) for each home assignments. The final grade is calculated according to clause 3.3 in accordance with the general rules of rounding.

For those who fulfil the attendance requirements, the MT and CT grades are determined as follows:

excellent (5) | 80 <= P |

good (4) | 70 <= P < 80% |

satisfactory (3) | 60 <= P < 70% |

passed (2) | 50 <= P < 60% |

failed (1) | P < 50% |

3.6 Retake and repeat

- A second retake for the mid-semester test (MT) is provided on the delayed submission period with a charge.
