Developing 3D–models for training facilities of a space complex

Abstract

The paper discusses problem statement for and software implementation of a Graphic Package Adaptation System (GPAS) intended for reading and processing graphic design data, produced by the CAD system PTC Creo. The idea is to introduce into the process of building a 3-D model of a spacecraft for training facilities an additional operation of ‘automated adaptation of the graphic package’. The proposed process does not exclude manual refinement of the model, however, including additional automated components into the process makes it possible to significantly reduce human effort required to build a model for training facilities. The exchange of models between PTC Creo, GPAS and Autodesk 3ds Max is conducted at the level of the open format Virtual Reality Modeling Language (VRML). The paper describes GPAS architecture, provides views of work windows of the program, and methods of running its main functions. Key words: Digital design model, polygonal model, simplification, graphic design data.
