The "Alignment" object is used to define the alignment of a road or bridge.

  • Station: The station of the starting point of the alignment.

  • Azimuth: The angle that the initial alignment makes with North, expressed in radians. Zero azimuth corresponds to North (optional).

  • Latitude: Defines the starting point of the route based on the X axis (optional).

  • Longitude: Defines the starting point of the route based on the Y axis (optional).

  • Elevation: Defines the starting point of the route, together with Latitude and Longitude. It is also known as the elevation.

Example Syntax:

</O

Example:

Code Block

<O N="AlignmentObject1" T="Project" Category="3D Geometric Objects" TransAlignRule="Right">
    <!-- created by ParamML Examples on 02.02.2023 -->
    <O N="Route" T="Alignment" Station="300" Azimuth="PI/2" Lat="0" Lng="0" Elev="1000" />
    <O T="Line" Alignment="Route">
        <O T="Point" X="0" Y="0" Z="0" />
        <O T="Point" X="10" Y="0" Z="0" />
    </O>
</O>

"Route" object contains Alignment parameters.
