Almost all input data tables which specify data along the pipeline can be 'toggled', i.e. the column(s) defining where on the pipeline the subsequent data is to be applied can be changed by the user. This allows the user to choose the most convenient way to enter the point's data.

The following 'toggle states' are defined:

Abbreviation

Name

Description

X-P

X-coordinates

Define the point(s) by the absolute x-coordinate.

Info If the pipeline has several points with the same x-coordinate, the data is applied to all those points!

AX-L

Along pipeline axis

Define the point(s) by the distance from the pipeline origin along the pipeline axis.

Info The distance is relative to the pipeline origin, AX-L = 0 is the pipeline origin irrespectively of its offset.

AX-LP

Along projected pipeline axis

Define the point(s) by the distance from the pipeline origin along the projection of the polygon lines on the horizontal X0Y-plane.

Node

Node number

Define the point(s) by its node number.

Info In this state, it is not possible to define a point between nodes.

Element

Element number

Define the point(s) by its element number.

Info The actual coordinate is the middle of the element. In this state, it is not possible to define a point somewhere else on that element.

Identifier

Identifier

Define the point(s) by its identifier label. You can choose between labels defined in the POLYDIF-table and those additionally defined in the ADIDENT-table.

 

Info For tables SISPRC, PIPES, SUPPORT and ADIDENT (tables from design function 2) an extra 'Δ' is added to the abbreviations because these 'distances' are relative to a REFIDENT column.

Warning If in a row of these tables:

-

a REFIDENT is undefined, the value in the column with the Δ abbreviation will be interpreted as absolute value.

-

a Δ abbreviation is undefined, it is considered to be zero.

-

both fields are undefined, the resulting AX-L will be zero.

REFIDENT

 

Warning The same rules apply when toggled to ΔX-P and ΔAX-LP

Warning When toggled to Δ Node/Element also the same rules apply, except when the REFIDENT is undefined, then the Δ Node/Element will be interpreted as the absolute Node/Element number which should always be greater then zero. So, when both fields are undefined, Node/Element number zero will result in an error during calculation of the design function.

Warning When toggled to 'Identifier' the REFIDENT should be left empty, otherwise an error will be reported during calculation of the design function.
