User Defined Connections: Settings that are locked (
) in a user defined connection file will automatically be locked on a member edit window for which that file is the " Input connection type ." You can, if you so choose, manually lock additional settings on the member edit window, and your changes will be retained, through multiple processes, so long as you do not change to a different connection then switch back to the original user defined connection.

Bottom Gusset One Membe r
Weld size: The weld size used to shop weld the framing edge of the bottom gusset plate to the bottom flange of the beam. See the example .
Thickness ( not depicted ): The " Material thickness " of the bottom gusset plate.
Width: The distance between the framing edge of the bottom gusset plate and the edge of the bottom gusset plate that is parallel and opposite to the framing edge (see example ).
This distance is perpendicular to the work line of the supporting beam.
Length: The length of the framing edge of the bottom gusset plate (the edge that welds to the beam bottom flange -- see example ).
Plate length is measured parallel with the work line of the beam.
Refx: The positive (+) or negative (-) distance (parallel with the supporting beam's work line ) from the work point of the wide flange horizontal brace to the corner of the framing edge of the bottom gusset plate that this end of the horizontal brace points toward (this also happens to be the nearest corner -- see example ).
A " Refx " of ' 0 ' aligns the corner of the bottom gusset plate with the brace's work point. Entering a positive (+) distance moves the corner of the bottom gusset plate parallel with the work line of the beam toward the opposite end of the horizontal brace. Entering a negative (-) distance moves the bottom gusset plate parallel with the work line of the beam in the direction that this end of the horizontal brace points toward. Changing the " Refx " moves the plate only, not the holes on the plate.
Refy: The positive (+) or negative (-) distance (perpendicular to the framing edge of the bottom gusset plate) from the work point for this end of the wide flange horizontal brace to the framing edge of the bottom gusset plate (see example ).
A " Refy " of ' 0 ' aligns the framing edge of the bottom gusset plate with the work point. Entering a positive (+) distance moves the gusset plate away from the work point toward the opposite end of the horizontal brace. Entering a negative (-) distance moves the gusset plate in the direction that this end of the horizontal brace points toward. Changing the " Refy " moves the plate only, not the holes on the plate.
Refz ( not depicted ):
Cut depth: The distance (perpendicular to the work line of the beam) from the corner of the framing edge of the bottom gusset plate that this end of the horizontal brace points toward to where the plate begins to taper (see example ).
Cut length: The actual length of the edge of the bottom gusset plate that is parallel to and opposite to the framing edge of the gusset plate (see example ).
Fill plate thickness ( not depicted ): The " Material thickness " of the fill plate.
For a non-sloping horizontal brace, the thickness of the fill plate should be equal to the difference in elevation between the bottom flange of the wide flange horizontal brace and the the top face of the bottom gusset plate. The top face of the bottom gusset plate should be at the same elevation as the bottom flange of the supporting beam.
Fill plate width: The distance between the two edges of the fill plate that are parallel to the work line of the wide flange horizontal brace. This distance is measured perpendicular to the work line of the brace (see example ).
Fill plate length: The distance between the two edges of the fill plate that are perpendicular to the work line of the wide flange horizontal brace. This distance is parallel with the work line of the brace (see example ).
Fill plate refx: The distance from the work point for this end of the wide flange horizontal brace to the nearest edge of the fill plate (see example ).
Increasing this distance slides the fill plate back toward the opposite end of the horizontal brace. The plate will remain at the same elevation (in the same plane if this is a sloping horizontal brace).
Fill plate refy: The distance from the work line of the horizontal brace to the length edge of the fill plate (see example ).
