Location
Girder: Specify the girder for which the crossframe will be generated.
Skew Angle: 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[Start/End]: The station of the cross-frame can either be defined using the options Start/End or through a manual definition.
Sections
Top Chord Section: Assign a section for the top chord, which can be imported from the AISC database by the users. The finite element representation is in the form of a truss.
Diagonal Chord Section : Assign a section for the diagonal chord, which can be imported from the AISC database by the users. The finite element representation is in the form of a truss.
Bottom Chord Section: Assign a section for the bottom chord, which can be imported from the AISC database by the users. The finite element representation is in the form of a truss.

Gusset Plate
The parameters listed below are exclusively used for 3D representation. "Gusset Plate" objects defined under the 'Properties' tab are assigned here.
Top Gusset Plate: Assign a previously defined gusset plate to the topside.
Bottom Gusset Plate: Assign a previously defined gusset plate to the bottom side.
Center Gusset Plate: Assign a previously defined gusset plate to the center plate.
