## 1 Introduction
Therefore, to enable the efficient operation of robotic total stations employed in deformation monitoring systems, it is necessary to ensure the proper construction of the survey station, adapted to the best possible extent to local conditions and the geometry of the control network. The observation

Current geoinformation technology, dynamic progress in the field of robotics, and 3D printing allow for the development of optimal solutions for the construction and operation of geodetic deformation monitoring systems. In particular, thanks to the possibility of printing even significant structural objects [18; 19], the use of 3D printers is becoming commonplace. One can even talk about the technologically advanced new generation of civil engineering [20; 21]. Recent developments in this field are also subject to that termed Industry 4.0 [22], which has come to dominate the manufacturing. Such a philosophy utilizes web-based and often artificial intelligence (A.I. )-oriented solutions, employing the Internet of Things (IoT). All this makes it possible to work autonomously, in a standardized, repeatable, and predictable way [23]. What is more, the presented issues are widely used by different industries--from civil engineering to aerospace. Depending on the material used, the 3D printing process can be lengthy and tedious. Therefore, it is necessary to properly select both the material from which the print will be made, as well as optimize the product shape. For this purpose, it is necessary to develop an efficient methodology--a specific technological line supported by conceptual modeling. Formalizing the process will therefore play a key role in automating the design and implementation work [24]. In this article, the authors described their own development of an automated technological line supporting the construction of dedicated protective housings for robotic total stations used in geodetic deformation monitoring. The designed solution allows for achieving the highest possible accuracies with the maximal protection of the instruments exposed to harsh field conditions. At the same time, the dedicated housing is light and pouring water resistible. This concept was formalized in the form of the unified markup language (UML) modeling [25]. To describe the concept of both the service of the 3D print of the protective housing and the web application serving that service, the Unified Modeling Language (UML) and the ISO 19100 geographic information standards [26; 27] were used. As conceptual modeling is the process of creating an abstract description of some portion of the universe of discourse and a set of related concepts, the conceptual models are representations of how tasks should be carried out and are used as a way of systematizing processes. The conceptual models in this study are presented as UML active, sequence, and class diagrams. A more detailed description is developed in Section 2. As a result, a ready-made prototype of a dedicated 3D housing was elaborated based on the conceptual modeling. The modeling process and formal diagrams are demonstrated in Section 3. Next--Section 4 contains the discussion, while the final conclusions are presented in Section 5.
