Skew Angle [deg]: A positive skew value rotates the cross frame in a clockwise direction, while a negative skew value rotates it in a counterclockwise direction. It is important to remember that the cross frames are positioned at the specified station along a line perpendicular to the PGL, which is then rotated according to the entered skew value.
...
Station [ft][Start/End]: Enter the station along the PGL. When dealing with curved girder bridges, collecting distance along the girder length can lead to different inputs for the right and left girder that are connected by cross frames, causing ambiguity. Therefore, collecting the station along the PGL is a more reliable solution to avoid such issues. Furthermore, since cross frames are typically continuous in the transverse direction, entering the same station for all cross frames ensures that their locations are consistent between each girder.

Sections
The parameters listed below are employed for 3D representation and are integrated into the gusset plate code section of the cross frame code check object's design process. They do not introduce any additional stiffness into the finite element analysis. Nonetheless, if you choose to perform load computations based on the stiffener and gusset plates, they will impact the weight calculation.
