Abstract
The paper illustrates a way of realizing two-dimensional draftings of mechanical devices, with application at internal combustion engines transverse section. Although the program draws a V-engine cross-section, the code above this program represents a resource for any user that wants to develop his own objects and assembly them. The strength of the code lies in the method of creating and sketching objects in a OOP strategy, and, finally, in the fact that this code offers an effective and easy tool for anyone who intends to create its own 2D structure, and see it on the screen, by editing a little structured text file that contains references to objects stored in other kinded data text files. Animation capabilities included.
