Here are some key features of "QSpider":

· Mathematical modelling of spatial mechanisms with use of multilevel representation of mechanical systems. The given approach allows to simplify and reduce the time construction.

· Modelling of auxiliary elements of the equipment, for example, the rotary tables, special adaptations, etc.
· The main feature of the program is global parameterisation of model. Any of model parameters can set a variable. The program allows to enter defined a mathematical parity in the form of mathematical expressions and to modify all model at change of another or other sizes (parametres) of model.
· Construction of constructive elements of mechanisms (the basis, a platform, a bed, etc.).

· Multilanguage interface.

· Independent sources of the program.
