Aim
With the help of the subject, students get to know the operation of integrated CAD systems, the types and details of model documentation, the characteristics of design automation, and the requirements of body-specific body and surface modeling. They gain practical knowledge in the fields of 3D component modeling, 3D curve generation, free-form surface modeling, model repair. In addition, the subject introduces them to the application of mathematical tools, molded and injection molded part design, and mechanism modeling.

Ability
Able to create computer models in a given CAD system, even to build combined part models. Creates parametric, flexible models using special shape features. Able to create associative mechanical assemblies by combining parametricly constructed part models using special shape features. Able to correct and modify possible faulty body models using shape features that can be applied during surface modeling. Apply what Student has learned to build computer models of cast and injection molded parts. Using modern computer methods and knowledge, it solves special technical problems in its field in an innovative way. It proposes a multifaceted interdisciplinary approach and solution to specific problems within its field. Prepares the documentation of the completed models, which can be easily, quickly, modified at any time as required. It proposes a complex process for computer automation of design. Creates the geometrically optimized model using the integrated design system. Designs a model of the plane mechanism suitable for motion simulation.
Attitude
Student constantly monitors students work, results and conclusions. It continuously expands students knowledge in the field of computer-aided mechanical design. Open to the use of information technology tools. It seeks to learn and use computer-aided design methods and tools. It publishes its results in the expected format. Open to learning about and accepting computer technology developments in the technical field. It strives for an accurate and error-free solution.
Independence and responsibility
Collaborates with the instructor and fellow students to expand knowledge. Accepts well-founded professional and other critical remarks. It suggests ways to apply the new knowledge. With students knowledge, student makes a responsible, well-founded decision based on students analyzes. Student is committed to the principles and methods of systematic thinking and problem solving. Independently thinks through computer-aided mechanical design tasks and problems and solves them based on specific resources.
Teaching methodology
The lectures basically introduce the students to the information defined by the knowledge competence elements using the technique of frontal education. The lectures include slide shows published in advance on the subject's website, so students can add their own notes to the lecture. Lecture outlines without attending the lecture are not enough to achieve proper preparation. If possible, external lectures will color the methods of knowledge transfer. Independent practical sessions promote the acquisition of knowledge at a skill level with topics other than lectures and the transfer and application of practical knowledge. During the exercises, the knowledge given by the supervisor in the first half of the lesson is applied by the students together with the instructor in a guided way, and then on an independent task solution. Access to the software is supported by open lab sessions beyond contact hours, in which case students can use the tools basically without the help of instructors.

General rules
Learning outcomes are assessed on the basis of a mid-year summary written performance measurement and a partial performance assessment (homework). Summative academic performance evaluation: the method of written evaluation of the type of competence elements of the knowledge that can be acquired in the lectures and practices of the subject in the form of an indoor dissertation, the available working time is 45 minutes. Partial performance assessment is a complex way of assessing the knowledge, ability, attitude, as well as independence and responsibility type competence elements of the subject, the form of which is the individual homework.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | summative assessment | |
| Number: | 1 | |
| Purpose, description: | Summative assessment assesses students ’learning outcomes determined by knowledge and ability type competencies. Accordingly, each summative assessment assesses the acquisition of the designated theoretical knowledge as well as the existence of knowledge and the application of skills acquired in practice. They will be completed on the date specified in the academic performance assessment plan, scheduled for the 12th week of education. A total of 50 points (practical part 20 points, theoretical part 30 points) can be obtained in the summary performance evaluation. | |
| Mid-term assessment No. 2 | ||
| Type: | formative assessment, project-based, complex | |
| Number: | 1 | |
| Purpose, description: | During the partial performance evaluation, a complex modeling task must be developed independently in the form of a homework. The preparation of the task is supervised by the practice leader, who provides an opportunity for consultation during each practice. During the assignment, the supervisor makes sure that the task is developed independently by asking questions about the model read in practice and by repeating the preparation of certain elementary details. After the successful presentation of the task, the task must be uploaded to the intelliFiles (gt3.intellifiles.eu) document management system at the specified location in the specified form, by the deadline specified in the schedule (plan. Week 14). You can get 50 points with this task. | |
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 | 50 % |
| Mid-term assessment No. 2 | 50 % |
The weight of partial exams in grade

Determination of the grade
| Grade | ECTS | The grade expressed in percents |

| The way of retaking or improving a summary assessment for the first time: | ||
| the summative assessments can be retaken or improved only combined | ||
| Is the retaking-improving of a summary assessment allowed, and if so, than which form: | ||
| one single, combined retake or grade-improving exam is possible for all assesments | ||
| 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 | ||
