Aim
The aim of the subject is to introduce the basic methods and tools of computer aided mainly mechanical design, and to present the possibilities of application in design. With practice-oriented training, learning the basics of geometric modeling and the use of modules that support engineering work, and the application of related engineering work opportunities in the different phases of the design process.

Ability
They interpret the generally used conceptual system of computer aided design. They use the basic elements and functions of a computer aided design environment. It uses the geometric foundations of computer aided modeling. They deal with the methods and tools of parametric computer modeling. They apply the main steps of feature-based part modeling. They select the most appropriate of the operations that can be performed with the building blocks of the models. They prepare complex structures and assemblies consisting of several parts. They select the tool and method for handling assemblies. They manage the modules used to document computer models. They distinguish between the basic methods of body and surface modeling and some of their special applications. They explore the computer aided design methods and procedures used to solve mechanical engineering design tasks.
Attitude
They create the cooperation during the expansion of knowledge with the instructor and fellow students. Expand their own knowledge with new material and information. They are open to the wide use of information technology tools. They strive to learn and routinely use computer aided design methods and tools. They organize the solution of the task into a system, thus achieving a more accurate and less error-prone final result. They are receptive to the implementation of the principles of energy efficiency, environmental awareness, and sustainable development and production in the solution of computer aided mechanical design tasks.
Independence and responsibility
They make decisions about solving computer aided mechanical design tasks and problems. They compare the available resources and how they are used. They accept and consider well-founded critical comments. In some situations - as part of a team - they cooperate with his fellow students in solving tasks. They are committed to a systematic approach in his thinking.
Teaching methodology
Within the framework of the subject, theoretical knowledge materials are delivered in the form of a one-hour lecture per week. In the framework of the computer lab exercises (two hours per week), the main goal is to present the basics of shape-based, parametric, 3D mechanical engineering design. All this in an interactive form, with the active involvement of the student, the use of IT tools and techniques, and the application of several different mid- and high-end design systems.

General rules
The formulated learning outcomes are evaluated based on three mid-year written performance assessments (summary academic performance evaluations), a homework assignment (partial performance evaluation), and active participation in laboratory exercises. The complex, written evaluation of the knowledge and ability-type competence elements of the subject takes place in the form of a closed paper. The 2nd midterm is used to check the mastery of the theoretical material presented in the lectures. Midterms 1 and 3 basically focus on the application of the acquired knowledge, so the problem is recognized and solved, i.e. practical tasks (modelling, drawing) to be solved during the performance evaluation. The homework is the creation of a three-dimensional solid model of a specific construction and the preparation of its technical documentation.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | summative assessment | |
| Number: | 3 | |
| Purpose, description: | The 1st midterm: several small modeling tasks (to be worked out on a computer), the part of the curriculum that forms the basis of the evaluation is determined by the instructor in charge of the subject in agreement with the practice supervisors, weight: 20%; 2nd midterm: questions related to the theoretical curriculum, weight: 20%; 3rd midterm: assembly modeling/drawing task (to be developed on a computer), the subject-matter part of the evaluation is determined by the instructor in agreement with the supervisors, weight: 20%. For each performance assessment, at least 40% of the maximum possible score must be achieved in order to pass. | |
| Mid-term assessment No. 2 | ||
| Type: | formative assessment, simple | |
| Number: | 1 | |
| Purpose, description: | A complex evaluation method for the subject's competence elements such as knowledge, ability, attitude, as well as independence and responsibility, which takes the form of individually prepared homework with the preparation of technical drawings, weight: 40%. At least 40% of the maximum possible score to be achieved to pass. | |
Detailed description of assessments performed during the examination period
The subject does not include assessment during the examination period.
The weight of mid-term assessments in signing or in final grading
| ID | Proportion |
|---|---|
| Mid-term assessment No. 1 | 60 % |
| Mid-term assessment No. 2 | 40 % |
The weight of partial exams in grade
There is no exam belongs to the subject.
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 85 % |
| very good (5) | Very Good [B] | 85 % - 85 % |
| good (4) | Good [C] | 70 % - 85 % |
| satisfactory (3) | Satisfactory [D] | 55 % - 70 % |
| sufficient (2) | Pass [E] | 40 % - 55 % |
| insufficient (1) | Fail [F] | below 40 % |
The lower limit specified for each grade already belongs to that grade.
Attendance and participation requirements
The lack of the value means that there is no attendance requirement.
At least 70% of laboratory practices (rounded down) must be actively attended.
Special rules for improving, retaken and replacement
The special rules for improving, retaken and replacement shall be interpreted and applied in conjunction with the general rules of the CoS (TVSZ).
| Need mid-term assessment to invidually complete? | ||
| yes | ||
| Can the submitted and accepted partial performance assessments be resubmitted until the end of the replacement period in order to achieve better results? | ||
| NO | ||
| The way of retaking or improving a summary assessment for the first time: | ||
| each summative assessment can be retaken or improved | ||
| Is the retaking-improving of a summary assessment allowed, and if so, than which form: | ||
| retake or grade-improving exam possible for each assesment separately | ||
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
| The way of retaking or improving a partial assessment for the first time: | ||
| partial assesment(s) in this group can be improved or repeated once up to the end of the repeat period | ||
| Completion of unfinished laboratory exercises: | ||
| missed laboratory practices may be performed in the repeat period, non-mandatory | ||
| Repetition of laboratory exercises that performed incorrectly (eg.: mistake in documentation) | ||
| incorrectly performed laboratory practice (e.g. Incomplete/incorrect report) can be corrected by repeating the practice | ||
