------ General settings ------

Piecemark: The submaterial piecemark ( up to 61 characters ) for the flat bar whose settings you are reviewing.

Also see: Flat bar system piecemarks begin with the material mark prefix for " Flat bar ." For the quantity of flat bars that have been assigned this piecemark, refer to the " Current quantity " listed on this material's General Information window.

Material thickness: The thickness (in the primary dimension " Units " or in other units ) of the flat bar being reviewed. This dimension is measured along the flat bar's Z material axis .

Material width: The width (in the primary dimension " Units " or in other units ) of the bar stock being reviewed. This dimension is measured along the flat bar's Y material axis . The width of the bar may be longer than the flat bar's length.

Material length: The distance (in the primary dimension " Units " or in other units ) from the furthest point on the material's left end to the furthest point on the material's right end. This distance is measured parallel with the material's longitudinal axis ( X material axis ).

Note: If the " End cut angle " of the flat plate is ' 0 ' for both the left & right ends, " Material length " is the " Work point distance " minus the left & right " Material setback ."

Work point distance: The distance (in the primary dimension " Units " or in other units ) between the work points of this flat bar.

Note: The longitudinal axis of the flat bar is defined by its two work points. In the material coordinate system, this axis is the X material axis .

Angle of twist: 0 (zero) degrees or the positive or negative (-) number of degrees of twist about the longitudinal axis ( X material axis ) of the flat bar.

' 0 ' (zero) results in straight (not twisted) material.

Entering a ' number of degrees ' rotates the right end the number of degrees entered while the left end of the material remains fixed. Assuming you are looking from the right end toward the left end of the material, a positive number of degrees rotates the material counterclockwise.

Rolling operation: None or Camber or Weak axis or Strong axis . The center of curvature for each of these choices (except ' None ') is midway between the left and right ends of the flat bar.

' None '
' Camber '
' Weak axis '
' Strong axis '

' None ' means the flat bar straight (not curved).

' Camber ' indicates parabolic bending along the strong axis of the rolled section with the ends fixed. The " Mid-ordinate " sets the offset at mid-span and the direction (+ or -) of that offset.

' Weak axis ' or ' Strong axis ' rolling indicates bending that is circular. The two ends of the flat bar are not fixed; that is, if the ends were vertical before the operation, they may not be vertical afterwards. The value entered to " Mid-ordinate " or " Included Angle " or " Rolling radius " sets the amount of curvature. A " Spiral offset " may also be set.

Mid-ordinate: The positive or negative (-) distance (in the appropriate " Units ") that the flat bar is offset at mid-span when the " Rolling operation " is ' Camber ' or ' Strong axis ' or ' Weak axis '. The sign (+ or -) sets the direction of offset.

Camber with a positive mid-ordinate ( +m )
Camber with a negative mid-ordinate ( -m )

Weak axis rolling with a positive mid-ordinate
( rolling toward the near side )
Weak axis rolling with a negative mid-ordinate
( rolling toward the far side )

Strong axis rolling with a positive mid-ordinate ( +m )
Strong axis rolling with a negative mid-ordinate ( -m )

Included angle: The positive or negative (-) number of degrees that sets angle of curvature when the " Rolling operation " is ' Strong axis ' or ' Weak axis '.

i = included angle. Extrapolate a circle from the inside curvature of the material, then draw a line along each end of the material. The lines will meet at the center of the imaginary circle, and their included angle is the angle entered here.

If the left end of the flat bar is to your left, a ' negative (-) number ' of degrees indicates the center of the flat bar is lower on the screen than its two ends. A ' positive number ' of degrees indicates the center of the flat bar is higher on the screen than its two ends.

Rolling radius: A positive or negative (-) distance (in the primary dimension " Units " or other units -- up to +/- 120,000 inches) that defines the amount of curvature of the flat bar when the " Rolling operation " is ' Strong axis ' or ' Weak axis '. The smaller the " Rolling radius " (+ or -), the greater the curvature.

r = rolling radius. If you were to extrapolate a circle from the inside curvature of the material, the distance from any point on the inside curve of the top/bottom flange to the center of the circle is the distance entered here.

If the left end of the flat bar is to your left, a ' negative (-) rolling radius ' indicates that the center of the material is lower on the screen than the two ends. A ' positive rolling radius ' indicates that the center of the material is higher on the screen than the two ends.

Spiral offset: The positive or negative (-) distance (in the primary dimension " Units " or other units ) that the right end of the flat bar is offset from its original work point. The left end of the flat bar is fixed. This applies when the " Rolling operation " is ' Weak axis ' or ' Strong axis '.

If the flat bar was input in a plan view, a ' positive distance ' raises the elevation of the right end. A ' negative (-) distance ' lowers the elevation of the right end.

Steel grade: Any grade of steel ( A36 or A572 or etc.) from the Steel Grades for Plates & Bar Stock table in Job Settings may be shown here as the steel grade for this flat bar.

Depth reference point: Center or FS or NS . ' FS ' stands for far side, ' NS ' for near side. The setting shown here indicates the position of the flat bar's " Material thickness " with respect to its workline.

' Center '
' FS '
' NS '
A section view of the same flat bar, but with different depth reference points. The view looks perpendicular to the plan view (at 100 ft) in which the flat bar was added.

' Center ' indicates that the thickness of this flat bar is centered with respect to the bar's work points.

' FS ' indicates that the far-side face of the flat bar is in the same plane as the bar's work points.

' NS ' indicates that the near-side face of the flat bar is in the same plane as the bar's work points.

Note: The flat bar's " Reference elevation ," which is reported on the General Information window, is the elevation of the left-end work point of the flat bar. Assuming that both work points of the flat bar are at that elevation, the " Depth reference point " tells you whether the flat bar material is centered at that elevation, or above that elevation, or below that elevation.

Surface finish: None or Sandblasted or Red oxide or Yellow zinc or Gray oxide or Blued steel or Galvanized or Duplex Coating or Undefined 1 or Undefined 2 or Undefined 3 or Red oxide 2 or Any user added surface finish. This affects the colors of 'Solid ' members on erection views in the Drawing Editor . This also sets the color when "Output material color " is set to 'Surface finish ' for a VRML Export or a DWG/DXF Export . The "Color " ( not "Surface finish ") sets the color of this material in Modeling .

sand blasted red oxide yellow zinc user surface finish 1
gray oxide blued steel galvanized user surface finish 2

To assign a different surface finish, you can drop-down the current surface finish and select the one you want, or you can press the "file cabinet" browse button ( ) and double-click any surface finish that is on the list.

Auto or .

If this box is checked ( ), the material surface finish follows what is set on the member level.

If the box is not checked ( ), the material surface finish can be changed to whatever is available in the list of surface finishes. If the surface finish changes from what the member level has set, the auto checkbox will be unchecked automatically. When the auto check box is unchecked, the member edit window shows an information tag which notifies the user that an attached material is not following what was set on the member level.

Note 1: Submaterial piecemarks can be split apart by surface finish. All surface finishes that do not have the 'Break Marks Material' checked on can be applied to any like material with out the material splitting. If the 'Break Marks Material' is checked on then only like materials with that specific surface finish can have the same piecemark, and because the submaterial marks differ so would the member's piecemark.

Note 2:When exporting a KISS file using "model" as the "Data source " surface finish data on the materials are compiled into the KISS download as follows, with a few exceptions (G=galvanized, N= none or sandblasted, P= others). Those exceptions are:

  • If the box for "Finish" routing in KISS export setup is set to a user routing

  • If the user has adjusted the Abbreviation for any of the default provided surface finishes

  • If you are using a user added surface finish

In these cases you will get what is provided in either the User routing, or the abbreviation field. For other exports it will always provide the abbreviation in the 'surface finishes' settings page.

Tip 1: "Surface area" is reported on the General Information window -- and this can be used to estimate the amount of coating required and its cost.

Tip 2: Changing "Steel grade " "Color " and "Surface finish " do not cause the plate to be regenerated. This means that, if you change those settings only, material fit operations such as a Fit Exact may, optionally, be preserved.

Color: The color of the flat bar when it is displayed in solids form . Different colors may be assigned to materials that have the same submaterial piecemark . The color swatch next to the list box ( ) displays the color that is selected.

Setup: The default colors for member main materials and submaterials is set up on the Modeling Colors setup window.

Centered: or .

   Centered

If this box is checked ( ), the " Material width " ( Y axis ) of the flat bar is centered with respect to its workline.

If the box is not checked ( ), the flat bar's " Material width " is positioned above or below its workline, which runs along its " Material length ."

Note: " Centered " does not affect the workline's location within the global coordinate system ; it sets the flat bar's position with respect to its workline.

------ Left/right end settings ------

Material setback: The positive or negative (-) distance (in the primary dimensioning " Units ") that the left or right end of the flat bar is displaced from its work point.

Note: If the left & right " End cut angle " is ' 0 ' (zero), subtracting the left & right " Material Setback " from the " Work point distance " gives the actual " Material Length ."

End cut angle: Any angle from 89 to -89 degrees. The cut will be made along the Y material axis (width) of the flat bar.

If you are viewing the near side of the flat bar: ' 0 ' (zero) designates a square cut end; a ' positive angle ' is measured counterclockwise from a perpendicular bisector to the workline; a ' negative (-) angle ' is measured clockwise from a perpendicular bisector to the workline.
