The last decades have been characterized by the rapid development of computer technologies and its widespread use in various fields of science, education, production, etc. The sphere of law enforcement is no exception, including the use of these technologies for conducting expert research. At the same time, certain problems of digitalization (translation of information into digital form) of technical and forensic studies and, in particular, studies of handwriting studies, are still observed.
The article deals with the issue of the possibility of using the computer system AutoCAD in determining the identification signs in the handwriting examination of signatures.
Comparing the numerical values of handwriting features obtained for a number of samples and for the objects under study, at the stage of comparative research, it is possible to establish whether the resulting numerical values characterizing some individual graphic features of the signature under study do not go beyond the variability limits determined for samples of signatures of a certain person
Perhaps, by deepening and developing this method, it will be possible to identify such parameters that are characteristic only of the signature of a certain person.
It should be noted that the proposed method of numerical expression of some graphic features of signatures does not cover all the variety of these features. These are signs related to the shape of the movements, direction, curvature, sequence of execution, the method of beginning and ending movements, etc. Such incompleteness needs to be carefully refined and opens wide opportunities for further research.

Key words: signature, identification features, AutoCAD, coordinate system, signature line, limits of variability.
