When you access the Analytical View in OpenBrIM and navigate to the settings, a combobox will appear as shown in the figure. If you select the "Display Supports" option, it will display the degree of freedom status for each point or support.

As a result of the values given to the DOF (Degree of Freedom) parameters, the Analytical View will change as follows.

<O N="Node2" T="Node" X="0" Y="0" Z="30" Tx="-1" Ty="-1" Tz="-1" Rx="-1" Ry="-1" Rz="-1" />

Tx="-1" Ty="-1" Tz="-1" Rx="-1" Ry="-1" Rz="-1" />

There is no changed parameter.

All degrees of freedom are fixed.

Image Added

Tx="1" Ty="-1" Tz="-1" Rx="-1" Ry="-1" Rz="-1" />

This is the changed parameter → Tx=”1”

Tx's degree of freedom is free.

Image Added

Tx="1" Ty="1" Tz="-1" Rx="-1" Ry="-1" Rz="-1" />

This is the changed parameter → Ty=”1”

Ty's degree of freedom is free.

Image Added

Tx="1" Ty="1" Tz="1" Rx="-1" Ry="-1" Rz="-1" />

This is the changed parameter → Tz=”1”

Tz's degree of freedom is free.

Image Added

Tx="1" Ty="1" Tz="1" Rx="1" Ry="-1" Rz="-1" />

This is the changed parameter → Rx=”1”

Rx's degree of freedom is free.

Image Added

Tx="1" Ty="1" Tz="1" Rx="1" Ry="1" Rz="-1" />

This is the changed parameter → Ry=”1”

Ry's degree of freedom is free.

Image Added

Tx="1" Ty="1" Tz="1" Rx="1" Ry="1" Rz="1" />

This is the changed parameter → Rz=”1”

Rz's degree of freedom is free.

All parameters have "free" degrees of freedom, meaning that they can rotate freely without any resistance to external forces.
