Accompanying Axis

Accompanying axes are created with reference to existing axes in certain distances to them.

The distances can be defined in plan as well as in the profile as constant values or by means of tables.

The created accompanying axis is calculated based on this geometric input data as 3D spline.

The outputted stationing on the created accompanying axis is always the respective stationing of its reference axis and not the stationing on the accompanying axis itself. Structural members (girders) which are created along an accompanying axis therefore also have the same stationing as the reference axis.

Note: If the reference axis is not continuous but contains for example kinks, the accompanying axis is not automatically continuously interpolated, that means that overlaps or gaps occur at these positions.

To create an accompanying axis

1. Right-click on the entry of the axis which should serve as reference for the accompanying axis and select New Accompanying Axis from the context menu.

   A new accompanying axis is created in the menu Axis in the navigation tree.

2. Optionally, edit the name and confirm with the enter key.
3. Move the mouse in the View window to specify the desired first station (begin or end) of the accompanying axis on the reference axis, and confirm it with a mouse click
4. Move the mouse in the View window to specify the desired second station (begin or end) of the accompanying axis on the reference axis, and confirm it with a mouse click.
5. Define the following parameters for the accompanying axis in the opening input window or later in the Property window:

Start Station

If applicable, adapt the previously selected start station.

End Station

If applicable, adapt the previously selected end station.

Offset

Constant distance of the accompanying axis from the reference axis in plan.

Offset Table

Input or select a table defined in the menu Variations which describes the distance of the accompanying axis from the reference axis in plan along the stationing of the reference axis.

Note: The definition of an offset table overwrites a possibly simultaneously defined constant offset.

Difference in Height

Constant distance of the accompanying axis from the reference axis in global vertical direction (profile)

Table for Height

Input or select a table defined in the menu Variations which describes the distance of the accompanying axis from the reference axis in global vertical direction (profile) along the stationing of the reference axis.

Note: The definition of a table for the height overwrites a possibly simultaneously defined constant difference in height.
