In the introductory chapter, we focused on modern technology – augmented reality and it´s relationship to CAD modeling. We further analyzed the process of creating augmented reality and the basic conditions and tools that are necessary for it´s use in practice. In the experimental part, we described the creation of an augmented reality application for the SPIRAM 150 pump model. It consists of two parts. In the first part, we focused on the visualization of individual pump parts. In the second part, we created a procedure for assembling and disassembling the pump based on the existing documentation for the pump. This application can be used for product presentations and pump assembly.
