<points>

This part contains properties of joints. It is an obligatory part of XML file. Every member is marked by the element <line>. The range of supported attributes differs according to the joint type:

Absolute joints

Absolute joints support following attributes:

id

  • unique joint ID (obligatory)

x

  • The x-coordinate of global coordinate system. Optional. If not defined, the coordinate x=0 is used.

y

  • The y-coordinate of global coordinate system. Optional. If not defined, the coordinate y=0 is used.

z

  • The z-coordinate of global coordinate system. Optional. If not defined, the coordinate z=0 is used.

support

  • The number of support type, which corresponds to the ID in the part <supports>. Additionally, values "joint" (hinged support) and "fixed" (fixed support) are allowed. Optional .

coordinateSystem

  • The number of local coordinate system which defines the rotation of support. The number corresponds to the unique ID in the part <coordinateSystems>. Optional.

Relative joints

Relative joints support following attributes:

id

  • unique joint ID (obligatory)

line

  • The number of a reference member. The number corresponds to the ID in the part <lines> (optional)

fromStart/ fromEnd

  • The attributes which define the position of the relative joint on the reference member. If the attribute "fromStart" is used, the position is measured from the begining of the member. If the attribute "fromEnd" is used, the position is measured from the end of the member. The value of the attribute defines the distance from reference point. The value with the character % means that the distance is defined using per cents of the member length. Otherwise, the position is defined in meters. Obligatory.

support

  • The number of support type, which corresponds to the ID in the part <supports>. Additionally, values "joint" (hinged support) and "fixed" (fixed support) are allowed. Optional.

coordinateSystem

  • The number of local coordinate system which defines the rotation of support. The number corresponds to the unique ID in the part <coordinateSystems>. Optional.

Only structures with more than two absolute joints can be imported into the programs "Fin 2D" and "Fin 3D".

Part <points> with two absolute and three relative joints
