The "GridsXAlignH" and "GridsYAlignH" parameters allow you to change the alignment rules of the line definitions specified in "GridLinesX" and "GridLinesY". This is useful when the girders of a kinked bridge do not align with the gridlines.
For example, in the code snippet provided, the "GridLinesY" parameter is defined as "[GridLine1,GridLine4,GridLine3,GridLine2]" and the "GridsYAlignH" parameter is defined as "[Warp,None,None,Warp]". This changes the slope of the inscribed lines by overwriting the "GridsYAlignH" parameter for the "GridLinesY’s line Alignments” definition.
"GridsYAlignH" parameters are defined respectively.
GridLinesY="[GridLine1,GridLine4,GridLine3,GridLine2]"
GridsYAlignH="[Warp,None,None,Warp]"
The "GridsYAlignH" parameter is a parameter of the Alignment object.
The line-slope order of the parameters in parentheses is important. They are paired with each other.
These parameters operate within the context of the Global Coordinate System.
