Automatic obtaining of engine block in AutoCAD environment

This paper presents a software application used for block generating of an internal combustion engine based on a set of constructive parameters. The application runs in the AutoCAD environment and for the programming process it has been used OpenDCL and VisualLISP environments. After the process of generating the 3D model of the engine block in AutoCAD file is obtained. The software also can export the engine block model in a STL file that is a file format recognized by Rapid Prototyping machines.
