  1. 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?

    1. In a typical 3D coordinate system, there are three mutually perpendicular axes: X, Y, and Z. The Xpositive direction of the x-axis is horizontal and points to the right, the YZ-axis is vertical and the positive direction of the Z-axis points upwards, and the ZY-axis is horizontal and points towards the viewerpointing 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.
