Application of drawingless documentation in the design of a milling clamping device
 Schneider, David ; Michalec, Michal (referee) ; Svoboda, Petr (advisor)
The bachelor's Thesis describes the construction of a milling fixture for clamping a component on a machine tool using drawing-less documentation. Available methods of clamping workpieces for machining are described here, and the creation of drawing-less documentation is further explained. Today, in the vast majority of cases, classic drawing documentation is used, which is in many ways more tedious than the processing of described 3D digital data about the model. The work describes the creation of drawing-less documentation on a specific design solution of a milling clamping device. This solution is developed on the basis of three proposals for possible conceptual solutions for the clamping fixture. Complete, drawingless documentation of all individual parts of the product. The bachelor's thesis shows the advantages of drawing-less documentation compared to 2D drawings of components, but also mentions shortcomings that reduce the overall impression. A possible improvement that could simplify the presentation of digital model data is suggested.

Drawingless documentation in engineering
 Ronďoš, Radim ; Pouzar, Josef (referee) ; Svoboda, Petr (advisor)
This bachelor thesis deals with the research of the use of drawingless documentation in mechanical engineering. Drawingless documentation, or Model Based Definition (MBD), enables the transition from 2D engineering drawings to 3D CAD models annotated using machine readable annotations, the so-called PMI data. This thesis addresses both its use in industrial applications and its preservation using appropriate CAD formats. Studies especially in the field of inspection show positive results of MBD application in industry. For the proper functioning of PMI it is crucial that this data is reliably transferable. Therefore, this thesis investigated the portability of PMI data to GOM Inspect from a test component in the form of a bearing rack. The drawingless documentation in STEP AP242 format was compared with the scanned mesh of the part produced by 3D printing. 47 % of the generated PMI was successfully imported and evaluated. Human intervention would be required to transfer all the data, which could introduce errors into the transfer, and therefore these shortcomings must be minimised for companies using MBD. The findings were presented and discussed at the end of the paper.
