This thesis investigates the parametrization of a 3D drone wing model and the application of dimensional correction methods in the context of selective laser sintering (SLS) additive manufacturing. The primary objective of the study is to develop a geometrically configurable model capable of compensating for dimensional deviations that typically arise between the CAD design and the physical object due to thermal distortions and process-specific factors. A literature review was conducted, highlighting the importance of correction strategies in additive manufacturing, and a parametric model was created with integrated scaling compensation mechanisms. A "Python" based graphical user interface was developed to enable automated input of key model parameters and synchronization with the "SolidWorks" environment via COM interface. The experimental part included the fabrication of multiple model variants with differing geometries. Dimensional accuracy was evaluated using digital calipers, optical 3D scanning, and "SolidWorks" based comparison tools. Following the application of a correction factor, a significant reduction in dimensional deviations was observed. The findings confirm that the implemented compensation methodology effectively improves conformity between the digital and physical models and may be applied more broadly in the design of parametric components where precision is critical. The developed methodology and tools also demonstrate high applicability in practical engineering workflows and educational settings.

The master's thesis presents an analysis of computer-aided design (CAD) platforms, assessing their role and applicability in the contemporary context of engineering design based on theoretical analysis and practical research. The first chapter defines the functions of CAD platforms, their technological evolution, and significance in engineering, alongside an overview of the main commercial CAD development companies and their areas of specialization. In the second chapter, specific evaluation criteria for CAD platforms are identified, providing a basis for comparative analysis. The third chapter includes a practical case study, comprehensively comparing two CAD platforms: SolidWorks and Autodesk Inventor. The comparison evaluated modeling capabilities, assembly functionality, visualization quality, and effectiveness of finite element analysis. An expert survey using the Analytic Hierarchy Process (AHP) methodology determined the weighting of the evaluation criteria. The findings indicate that while both CAD platforms effectively meet basic design tasks, SolidWorks demonstrates a clear advantage in more complex design scenarios, particularly in the area of user interface ergonomics. These results provide valuable insights for engineering firms and professionals in making informed decisions regarding CAD software selection.

This paper examines the concept of digital twins and its application in the field of engineering design, emphasizing the application of parametric three-dimensional modeling methods. Digital twins allow the creation of virtual game equivalents that help to accurately plan, analyze and optimize solutions during the design process. The object of the study was chosen as the handbrake and gear lever models, which are relevant in the design of simulator systems. An analysis of existing designs shows that most current solutions are oriented towards ensuring ergonomics, but lack versatility and adaptability to different user needs. With the help of a parametric model, these components can be quickly and accurately adjusted by changing geometric parameters without changing the entire structure. The paper also analyzes the obstacles to the application of a parametric model and identifies the development prospects of this technology. Based on the analysis and modeling results, an overview is provided of how digital twins can be related to the engineering process in order to increase design efficiency, flexibility and product adaptability.

Human behavior and choices directly affect energy consumption, as daily decisions shape the overall energy demand, which impacts climate change. To reduce the negative impact, efficient energy use is encouraged. The goal of this thesis is to enable users to use energy sustainably by expanding the functionality of an existing behavior-changing mobile application. The analytical part included an analysis of enabling functions, identifying the most impactful solutions. These solutions were compared with the existing "Mano CO2" application. Feedback and goal-setting functionalities for the user were selected, and a concept for prototype development was created. The prototype development section describes the project's infrastructure, energy consumption reports, and the practical implementation of goal-setting functionalities. External artificial intelligence and machine learning models were used to fulfill the functionalities. The result of the work is the creation of prototypes for two additional functionalities for the "Mano CO2" application, with recommendations for further application development. The work consists of 63 pages, 24 illustrations, 5 tables, and 75 references. The project code is provided separately.

This work examines accuracy and repeatability issues in additive manufacturing, focusing on complex geometric objects such as threaded pairs. The study emphasizes how factors like printing speed, layer thickness, extrusion temperature, and plastic color affect the accuracy of fused deposition modeling (FDM) in additive manufacturing, thus creating the need to adjust three-dimensional object models to find their manufacturing error coefficient. The aim of the research is to develop a user-friendly three-dimensional parametric model of a compatible threaded pair, allowing for quick and precise modifications with minimal human errors. Experimental results for the created three-dimensional model of the compatible threaded pair identified a manufacturing error coefficient of 1.004069 and demonstrated that iterative adjustments can achieve a compatible threaded pair with accurate dimensions. This work provides valuable insights into improving production accuracy in additive manufacturing.

Resonant frequency tuning is an important engineering process used in applications ranging from bridges and buildings to piezoelectric systems. Currently, there are no software packages on the market that offer this automatic calculation capability, and most calculations are still performed manually or semi-automatically. Automation in this area can significantly facilitate the work of engineers and shorten the design process. The aim of this study is to develop an automatic model that allows the combination of the second bend and the first longitudinal resonant frequencies of the clamp. The work may be of interest to engineers and researchers working on resonant frequency tuning problems. It presents an automatic parametric model with spreadsheet integration that would enable the tuning of resonant frequencies automatically, without external intervention.

The aim of the master thesis is to create a simulation of any convex polygonal for turning operation tool using a graphical automated design system, which represents the process of the turning operation tool and to apply the simulation to educational applications. The paper describes turning tools, simulations in the AutoDesk software package and the importance of simulations in science. The results of the developed simulation are presented. It describes the three parts of simulation development - data collection, data analysis and simulation display. The results of testing with different parameters are also discussed. It concludes that AutoDesk can be used to create a simulation using the AutoLisp programming language. As the AutoLisp language is open source, such a programme could be used by anyone. Such simulations could help in the field of education and could be an inspiration and incentive for the AutoCAD community to develop open source applications.
