User Defined Connections: Settings that are locked (
) in the user defined connection file will automatically be locked on the member edit window. 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.

Gusset Intersection
( HSS, bolted welded tee end fitting )
Gusset Intersection
Thickness ( not depicted ): The " Material thickness " of the intersection plate material. The thickness is centered with respect to the work line of the supporting vertical brace.
Width ( plate width ): The distance (perpendicular to the work lines of the supported braces) between the two edges of the intersection plate that are parallel with the work lines of the supported braces (see example ). In other words, this is the length of either of the two short edges of the intersection plate. Increasing the intersection plate " Width " on both of the supported braces adds material down, toward lower elevations . Tip : The " Width " is symmetrical around the work point shared by the two supported braces if the " Refy " is half the intersection plate " Width ."
Length ( plate length ): The distance (parallel with the work lines of the supported braces) between the two edges of the intersection plate that are perpendicular to the work lines of the supported braces (see example ). In other words, this is the length of either of the two longer edges of the intersection plate. Increasing the intersection plate " Length " on both of the supported braces adds material to the end of the plate associated with the left brace. Tip : The " Length " is symmetrical around the work point shared by the two supported braces if the " Refx " is half the distance entered here.
Refx: The distance (parallel to the work line of the supported brace) from the work point to the edge of the intersection plate that the right vertical brace frames to (see example ). Increasing the " Refx " on both of the supported braces shifts the center of the intersection plate toward the right brace. Changing the " Refx " moves the plate only, not the holes on the plate.
Refy: The distance (perpendicular to the work line of either of the supported braces) from the work point to the upper longer edge of the intersection plate (see example ) .Increasing the " Y-reference " on both of the supported braces shifts the intersection plate upward in a direction perpendicular to the work lines of the supported braces. Changing the " Y-reference " moves the plate only, not the holes on the plate.

( HSS, bolted welded tee end fitting )
Thickness ( stem thickness ): The " Material thickness " of the stem plate. Increasing the " Thickness " moves the surface farthest from the gusset plate, while the other surface remains the " Refz " distance from the gusset plate. See example .
Width ( stem width ): The distance between the two corners of the forward edge of the stem plate. Since the stem plate is rectangular, this is also the length of the edge of stem plate that welds to the cap plate. The width of the plate is perpendicular to the work line of the vertical brace. See example .
Length ( stem length ): The length of either of the two edges of the stem plate that are parallel with the work line of the vertical brace. See example .
Refx: The distance from the work point of the vertical brace to the nearest edge of the stem plate (to its forward edge). This distance is parallel with the work line of the vertical brace. Increasing the " Refx " moves the stem plate and the cap plate along the work line toward the opposite end of the vertical brace -- it does not move the holes in the plate since hole placement is set on the gusset plate. Decreasing the " Refx " moves the stem plate and cap plate toward the supporting brace. See example .
Refy ( not depicted ): The distance from the work line of the vertical brace to the length edge of the stem plate (the length edge is parallel with the work line). This distance is perpendicular to the work line of the vertical brace in the same plane as the stem plate. Changing the " Y-reference " slides the stem plate sideways, perpendicular to the work line -- it does not move the holes in the plate since hole placement is set on the gusset plate.
Refz ( not depicted ): The distance from the vertical brace work line to the nearest face of the stem plate. This distance is parallel with the thickness of the stem plate. The default " Refz " is half the thickness of the gusset plate, which places the surface of the stem plate flush with the surface of the gusset plate. Increasing the " Refz " to a value greater than the default creates a gap between the stem plate and the gusset plate.
Stem Plate To Cap Plate Connection
Weld size: The weld size for shop welding the back edge (near and far sides) of the stem plate to the cap plate. This is labeled "stem weld" in the example .
Stem Plate To Gusset Connection
Hole type ( not depicted ): Standard round or Short slot or Oversized or Long slot or User slot #1 or User slot #2 . This is the hole type for all bolts on the vertical brace intersection plate. If you enter a different " Hole type " for each of the two supported braces, connection design uses the hole type entered for the left brace. A vertical brace intersection plate is a submaterial of the supporting (longer) pipe or tube brace and field bolts to the two supported braces.
Bolt diameter ( not depicted ): The diameter of the field bolts to be used to fasten the supported pipe or tube braces to the intersection plate. You can type in any diameter (inches or mm) or select a bolt diameter from the combo box's menu (
). Diameters listed on the menu come from Home > Project Settings > Job > Bolt Settings > the " Available bolt diameters " list. The bolt diameter entered here, together with the " Hole type " entered above, set the diameter of the holes the bolts goes into. The two braces can have different bolt diameters.
Rows: The total number of holes in a column of holes on the half of the intersection plate associated with the supported brace you are editing. Bolt rows on a vertical brace intersection plate run perpendicular to the work lines of the two supported vertical braces. In the example above, the number of " Rows " is ' 3 '. Both braces should have the same number of rows.
Distance to 1st hole along brace ( to 1st hole ): The distance (parallel with the work line of the supported vertical brace you are editing) from the work point to the first row of holes on the half of the intersection plate you are editing (see example ).
Hole spacing along brace ( row spacing ): The distance (center to center) between of any two adjacent holes in the same column of holes on the half of the intersection plate associated with the supported brace you are editing (see example ). Row spacing runs parallel with the work line of the brace.
End connection failure message: Invalid bolt spacing
Columns: The number of columns of holes for bolting to the intersection plate whichever supported brace you are editing. For the example above, this number is ' 2 '.
Hole spacing perpendicular to brace ( column spacing ): The distance (center to center) between columns of holes (see example ). An entry of ' 0 ' results in a single column of bolts.
Thickness ( cap thickness ): The " Material thickness " of the cap plate. Increasing the cap plate " Thickness " moves the back face of the cap plate toward the opposite end of the vertical brace, while the forward face of the cap plate remains the same distance from the work point. See example .
Width ( cap width ): The length of either of the two edges of the cap plate that are parallel with the near side or far side of the gusset plate. See example .
Length ( cap length ): The length of either of the two edges of the cap plate that are parallel with the thickness of the gusset plate. See example .
Refy ( not depicted ): The distance from the work line of the vertical brace to the length edge of the cap plate. This distance is perpendicular with the work line of the vertical brace in the same plane as the width edge of the cap plate. Changing the " Refy " slides the cap plate up or down along the width of the cap plate.
Refz ( not depicted ): The distance from the work line of the vertical brace to the edge of the cap plate. This distance is perpendicular with the work line of the vertical brace and parallel with the length of the cap plate. Changing the " Refz " slides the cap plate sideways, parallel with its length. The default centers the cap plate with respect to the work line (the neutral axis) of the HSS brace.
Weld size ( cap weld ): The weld size for shop welding the HSS, pipe or tube vertical brace to the cap plate. This is labeled "cap weld" in the example .
