Inaccurate finite element models and disconnected nodes/elements in the cross frame can occur if the entered station values are not >= the girder start station or <= the girder end station. This can cause stability issues in the finite element model. To ensure correct station input, users should select the start/end options from the station input. This approach is especially recommended for cross frames located at the beginning or end of girders.

Sections
Top Chord Section - Bottom Chord Section - Diagonal Chord Section: Assign a section for the top/, bottom/, or diagonal chord, which can be imported from the AISC database by the users. The finite element representation is in the form of a truss.data associated with this section is used for the 3D model of the object; however, the finite element model of the object will be generated regardless of whether the sections are defined or not.

Gusset Plate
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.
