Development of three-dimensional modeling systems for heat exchange equipment parts

heat exchange equipment;  3D solid modeling;  secondary development;  Parametric plotting

Using AutoCAD secondary development technology, a three-dimensional modeling system for heat exchange equipment parts was developed under the environment of Visual C++ 6.0 and ObjectARX 2000. Using extrusion, rotation and Boolean operations, given the basic parameters, the <>D solid model of the heat exchange equipment parts is automatically created, the design parameters are modified, and application examples are given. The system is convenient, time-saving, friendly interface, reliable operation, and realizes computerized parametric drawing from data to drawing. Practice has proved that the system saves time and improves the design analysis efficiency for the pre-processing and modeling of FEA parts of heat exchanger equipment.
