Supports
The joint support consists of three components: prevented displacements in directions of global axes Y and Z and prevented rotation about axis X. The support in the certain direction can be switch on by the corresponding check box "fixed". Following symbols are used in the workspace for different types of supports:

The most common support types can be entered with the help of dedicated buttons in the right bottom corner of the frame.
The support properties also contain the setting "Support is in local coordinate system". This option is useful for cases, where the reactions in the support has to be obtained in the rotated coordinate system or where the structure is supported in certain direction that isn't parallel to main axes. The local coordinate system of joint has to be specified first in the joint properties.
The button "Special" opens the window "Special properties of joint", where the spring supports may be defined.
The support styles are also described in the theoretical chapter "Supports".
