The flying vehicle with ducted rocket engine (DRE) developing at the preliminary design stage begins with forming the volume-weight layout of the product. Then, determining geometry of both engine characteristic sections and aerodynamic surfaces is required. These issues can be solved by tuning and optimizing with special software. The result of these studies represents the entire range of various technical information, such as characteristics of the DRE elements and, consequently, the engine altitude and speed characteristics, the airframe aerodynamic characteristics, flight dynamics parameters according to the technical specifications and, surely, preliminary size of the airframe and DRF basic elements. This allows making a drawing of all three views. However, further studies of the thermal state, aerodynamic and strength characteristics require a 3D-model.

To solve such problem, it is effective to employ automated design systems, since their capabilities are noticeably superior to human ones. Analysis of the software products available on the market (KOMPAS-3D; SolidWorks; Autodesk Inventor and others) revealed that practically there were no holistic tools for solving these problems at the moment.

At present, automated design, systems are employed for converting drawings into electronic form. Initially, a 3D-model is created manually according to the paper drawings, and the original drawings are already being recreated from it, but in the electronic form. Reducing the time interval from appearing the drawing of three views of the preliminary studies to the 3D-model is required for the studies simplifying and conceptual flaws revealing. Thus, creation of the unified program for real objects modelling presents great scientific and practical interest.

Such program can be obtained, combining the initial software package with one of the automated design systems. Thus, the possibility of immediate transition from the drawing of three views to the 3D- model will appear. Such program advent will significantly accelerate the process of 3D-models creation, which, in its turn will allow immediate conceptual flaws revealing and accelerate various kinds of studies.
