Why do the node coordinates show a negative y direction even though the positive transverse offset is going in the right direction looking ahead station in most bridge workflows?
In a typical 3D coordinate system, there are three mutually perpendicular axes: X, Y, and Z. The positive direction of the x-axis points to the right, the Z-axis is vertical and the positive direction of the Z-axis points upwards, and the Y-axis is horizontal and pointing away from you. However, in the context of bridge engineering, positive transverse offset values are typically used in the right direction when looking ahead at a station. To ensure consistency with how bridge engineers think, many library components in OpenBrIM Platform convert +Y values to -Y and -Y values to +Y in their input parameters.
