Displays when you place bracing members.
Placement Type
Select the member placement type.
Places linear members in the model by defining the member start and end locations one member at a time.
Columns by Grid Intersection Command
Places columns between two selected elevations at selected grid intersections.
Places beams on a selected elevation.
Places cross bracing between members that you select in the model.
General
Parent System
Specifies the parent system for the object. Recently used systems that are appropriate to assign as the parent system for this object display in the list along with the Select from Workspace and Select from Model options. The most recently used system displays at the top.
The parent system of the object must have an Approval Status of Working before you can change the Parent System value. If the Approval Status of the parent system is not set to Working, this value is read-only.
Select Interactively
Turns on or off the interactive selection. When this option is on, you can select the parent object in a graphic view or any of the explorers.
Select from Workspace
Displays the Select Parent System Dialog with the Workspace tab open. The workspace is the subset of the active model database you specified when you started your design session. Navigate the hierarchy to select the parent system, and then select OK.
Select from Model
Displays the Select Parent System Dialog with the Model tab open. The model is all the objects in the active model database, including those that are not part of your workspace. Navigate the hierarchy to select the parent system, and then select OK.
Type Category
Specifies the type category of the member, such as a beam or a column. The available member type and properties change depending on the member type category that you select. You can define a custom member type category by editing the Structural Member Type list in the Catalog task.
Type
Specifies the type of member, such as a beam or column. The available member properties change depending on the member type that you select. This property is a hierarchical child of Type Category. To change the options on the list, edit the Structural Member Type select list in Catalog.
Cross Section
Specifies the cross-section library, section type (W, MT, L, and so forth), and section
size to place. Recently used cross-sections are listed first. Use the search box to
locate the cross-section you need or click Browse Cross Section Data 
.
Browse Cross Section Data
Select to browse all the selected Section Types that are available in the selected Section Standard.
Material
Specifies the material type. For example, type Steel, Carbon, or Concrete.
Grade
Specifies the object material grade. To change the options on the list, edit the Structure > Materials > Properties node in Catalog.
Cardinal Point
Specifies the relative position of the structural cross-section to the member placement line. Nine cardinal positions (1-9) are available. The location of cardinal points 10 (center-of-gravity) and 15 (shear center) depend on the section shape. The local z-axis of the member and the center-of-gravity point of the section define cardinal points 11 and 14. The local y-axis of the member and the center-of-gravity point of the section define cardinal points 12 and 13. Cardinal points 10 through 15 are unavailable for designed members or cans.
Angle
Specifies the angle, in degrees or radians, by which the cross-section is rotated about the member axis. The zero-degree position is either the Z-axis or the X-axis of the active coordinate system depending on the member orientation. The active coordinate system is set using the Coordinate System control in PinPoint/Precision Input. The Angle property is not used when placing members using the Seated, Flush, or Centerline frame connections.
Reflect
Reflects or mirrors the cross-section about the member's local z-axis. This parameter affects both symmetric and asymmetric sections. For example, you can use this option to set flanges of a channel section to point in the opposite direction. The Reflect property is not available when editing members that have Seated, Flush, or Centerline frame connections.
Members and Type
Select First Member
Select the first member that you want the cross or chevron bracing between. If you are placing vertical bracing, this member is typically a column. If you are placing horizontal bracing, this member is typically a beam.
Select Second Member
Select the second member that you want the cross or chevron bracing between. This member must be coplanar and non-intersecting with the first member that you selected.
Select Third Member
Select the third member that you want the cross or chevron bracing between.
Select Fourth Member
Select the fourth member that you want the cross or chevron bracing between.
Bracing Type
Specifies the type of bracing to place. Select Cross to place two braces that cross. Select Chevron to place two braces as a chevron brace.
Offset
Defines the distance to place the supported members (the braces) from the supporting members. This offset is perpendicular to the plane of the supporting members.
Completion
Cancel (ESC)
Cancels all changes and exits the command.
Finish (CTRL + ENTER)
Saves all changes and exits the command.
Finish and Modify (CTRL + SHIFT + ENTER)
Saves all changes, and then selects the objects for modification.
Finish and Repeat (SHIFT + ENTER)
Saves all changes, and then restarts the command.
