Abstract: In the current article we present CAD realization of a newly proposed 20-segmental geometrical model of the human body of the average Bulgarian male. We perform the ensemble of the model of the whole body as a set of geometrical bodies for the separate segments of the body within the SolidWorks® CAD environment. In order to achieve this goal, the needed geometrical data is taken from a detailed anthropological investigation of the Bulgarian population [1]. One of the aims of the current work is to improve the 16-segmental mathematical model of the human body described in [2], shaping the body with 20 instead of 16 segments. The suggested CAD model of the human body of men is verified against the analytical results from our previous investigation [2], as well as through comparison with data available in the provided reports. We observe a particularly good agreement between our model results and data reported in the literature. Hence, our model, and the mass-inertial characteristics obtained, may be applied in studies of orthotics and prosthetics design, ergonomics, as well as or investigating criminology cases like body fall, car crash, etc. The model is also suitable for performing computer simulation in areas as medicine, robotics, sports, and others.
