The final stage of designing a cable network of spacecraft (as well as any other product) is the release of design and operational documentation. The automation of this process allows to improve the quality of documentation and de-crease the manufacturing time of spacecraft. The JSC ”Information Satellite Systems” (ISS) uses its own integrated software complex ”ALCAB” for releasing design documentation package for a cable network. For the assembly drawing development, the company uses CAD without integration with ”ALCAB”. In this regard, adding or removing items in the specification leads to the further refinement of the drawing. We propose the technique of solving a problem connected to the automation of the assembly drawing development for a cable network produced on a plane. The main task is to create associative link between the specification items and the cable network drawing. In this article we present the results of the analysis of the structure of the cable network 3D model designed in ”CATIA V5” CAD. There are schematic examples of harness topologies. The analysis identified the list of data to be extracted from the 3D model. We described the most interesting tools of ”CATIA V5” CAD that allow you to automate many processes including the development of your own software solutions. The analysis identified the tools for automated uploading of all re-quired data from the model. The examples of these tools are ”Knowledge Expert” and external programming environ-ment ”CAA RADE”. The analysis of their performance showed that the extraction of data using an algorithm developed with ”CAA RADE” was faster than using ”Knowledge Expert”. We described the potential of drawing tools in ”CATIA V5” CAD such as ”Electrical Harness Flattening” and ”Drafting” that allow you to automate the assembly drawing development. The paper proposes the method of automating he assembly drawing development of a cable network developed with the use of three-dimensional technology using the tools of ”CATIA V5” CAD and software designed at the JSC ”ISS”.
Keywords: spacecraft, cable network, automation, design documentation, assembly drawing.
