In the System-tree using a right click on “Shafts” additional shafts can be added to the system. The shaft can be defined by selecting it in the system tree.
Either shafts can be directly added, if only single or coaxial shafts are used. For general shafts systems groups or coaxial groups can be used to build shaft systems. Planetary groups are used for planet shafts to model planetary gear sets.
