At present, there are two parallel trends related to spacecraft development tasks and problems. From the one side, due to complexity of constructions and growing use of high-power large-sized antennas, it is necessary to consider the effect of self-shading and research the effects accompanying this phenomenon. From the other side, modern computer tools, especially GPUs (graphics processing unit), allow one to create "mini-supercomputer" based on "common" desktop/laptop and perform CAE (computer-aided engineering)-based processes using 3D models of different LOD (Level-of-detail). In this paper, we present a conception of SA parameters computer modeling based on hierarchical, property-based 3D-model of spacecraft. Thus, one can model different work modes of spacecraft on the project stage, with real-time prediction of effects related to space factors complex combination impact. The result is easy-to-edit, easy-to-calibrate "digital twin" of spacecraft which allows engineer to model and investigate complex space factors combination results for a different orbital work mode..
