Course detail
CAD Modeling
FSI-ZM1 Acad. year: 2022/2023 Winter semester
The course introduces the concepts and theoretical basis for the creation of CAD data, advanced modeling tools and methodology of work in 3D engineering parametric programs, creating parts and assemblies, adaptivity, parameterization, volume and surface modeling and drafting. Attention is paid to software design tools and their application to specific products. The course provides practical mastering of engineering tools realted with multi-disciplinary engineering tasks and problems, and integrates the knowledge acquired in basic studies in subjects focused on the design of machines and mechanisms.
