Aims of the course unit:
The course aims to acquaint the students with the theoretical basics of descriptive geometry. It will provide them with a computer aided training in basic parts of geometry.
Learning outcomes and competences:
Students will acquire the basic knowledge of three-dimensional descriptive geometry necessary to solve real life situations in various areas of engineering.
Prerequisites:
The students have to be familiar with the fundamentals of geometry and mathematics at the secondary school level.
Course contents:
Principles and basic concepts of three-dimensional descriptive geometry. Perspective transformation. Orthographic projection. Curves and surfaces. Intersection of plane and surface. Piercing points. Torus, quadrics. Helix, helicoid. Ruled surfaces.
Descriptive geometry is supported by a computer.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:
COURSE-UNIT CREDIT REQUIREMENTS: Draw up 5 semestral works (each at most 2 points), there is one written test (the condition is to obtain at least 5 points of maximum 10 points). The written test will be in the 9th week of the winter term approximately.

FORM OF EXAMINATIONS: The exam has an obligatory written and oral part. In a 90-minute written part, students have to solve 3 problems (at most 60 points). The student can obtain at most 20 points for oral part.
