The article proposes a simple, high-precision new graphic-analytical method for determining the absolute and relative speed of characteristic points of a spatial mechanism on a three-dimensional computer model. Also, for the first time, a procedure for constructing a three-dimensional computer model of the speed plan was developed and, using it, a three-dimensional computer model of the speed plan of a five-link spatial crank-rocker mechanism was built. The accuracy of the results obtained by the proposed method was confirmed by the constructed speed plan based on the velocity vectors obtained by the proposed method, using the example of a five-link crank-rocker mechanism and comparing it with the values calculated by the numerical method.
