# According to which coordinate system, are linear hinges aligned?

#### Answer

Axial/Shear Release or Spring

The degrees of freedom are based on the following definition of the axis: The axis x points in the direction of the line;

These text boxes or table columns control the degrees of freedom for axial and shear forces. If a check box is selected, it means that the displacement in this direction is possible and thus the force is not transferred.

It is also possible to enter the constant of a translational spring.

Moment Release or Spring

The degrees of freedom for the moments refer to the local axis system of the hinge (axis x in the direction of the line, axis y as tangent, and axis z as normal to the surface plane).
A check mark indicates that the rotation is free and the internal force is not transferred.
It is also possible to enter the constant of a rotational spring.

There is already an interesting article about line hinges available on our website .
