Specification of start coordinates of pipeline configuration (Input Table)

Table description:

The ORIGIN data table is used to define the starting point of the pipeline polygon within a GLOBAL coordinate system. This pipe origin (X0, Y0, Z0) can be defined at any location; however, the coordinates (0,0,0) are typically used for simplicity.

This global coordinate system should be right-handed and orthogonal, with the following axis orientations:

•X-Axis: Select a horizontal orientation, ideally aligning its positive direction along the general direction of the pipeline polygon (as defined in the input data table POLYDIF); however, any horizontal direction may be chosen.

•Z-Axis: Set vertically, with its positive direction oriented opposite to gravity.

•Y-Axis: Defined so that, along with the X- and Z-axes, it forms a right-handed global coordinate system.

The starting point is also defined in the following coordinate systems:

•NODE axis (node numbers: not necessarily starting with 1)

•AX-L axis (length coordinates along spatial pipeline axis)

•AX-LP axis (length coordinates along pipeline polygon projected on horizontal XOY-plane)
