Brace Instance Properties

Modify brace instance properties to change structural usage, offsets, justification, and more.

To change instance properties, select the element and change its properties on the Properties palette.

Name Description
Constraints
Reference Level The constraining level.
Cross-Section Rotation Parameter that controls rotating beams and braces. The angle of rotation is measured from the beam’s work plane and the direction of the center reference plane.
Construction (Pre 2014 projects)
Start Extension The dimension between the edge of the start end of the brace and the element to which it is connected.

This parameter is only available in projects created in versions prior to Autodesk Revit 2014 containing brace families that have not been updated. It is recommended to use the Geometric Position Start Extension below. Using both is an additive extension.

End Extension The dimension between the edge of the finish end of the brace and the element to which it is connected.

This parameter is only available in projects created in versions prior to Autodesk Revit 2014 containing brace families that have not been updated. It is recommended to use the Geometric Position Start Extension below. Using both is an additive extension.

Materials and Finishes
Structural Material Controls the hidden view display of structural elements. Concrete or Precast will display as hidden. Steel or Wood will be visible when another element is in front of it. Unassigned will not display if hidden by another element.

See Change the Physical Properties of a Material.

Structural
Start Connection The moment frame or cantilever symbol at the start end of brace, if applicable.
End Connection The moment frame or cantilever symbol at the finish end of brace, if applicable.

End Attachment Level Reference The constraining level of the finish end of the brace.
End Attachment Elevation The elevation of the finish end referenced from the End Attachment Level Reference.
Start Attachment Type Distance or Ratio. Type of measure of distance between brace start end and a designated beam end. Applies to the brace end attached to a beam.
Start Attachment Distance Available when Start Attachment Type is specified as Distance. Distance of separation of the brace start end from the designated beam end. Applies to the brace end attached to a beam.
Start Attachment Ratio Available when Start Attachment Type is specified as Ratio. Ratio (percentage) of separation of the brace start end from the designated beam end. Applies to the brace end attached to the beam.
End of Referenced Element Available when attached to a beam. Designated end (Start or End) of the referenced beam to which the start end of brace is attached. Applies to the brace end attached to the beam.
End Attachment Type Distance or Ratio. Type of measure of distance between brace finish end and a designated beam end. Applies to the brace end attached to a beam.
End Attachment Distance Available when End Attachment Type is specified as Distance. Distance of separation of the brace finish end from the designated beam end. Applies to the brace end attached to a beam.
End Attachment Ratio Available when End Attachment Type is specified as Ratio. Ratio (percentage) of separation of the brace finish end from the designated beam end. Applies to the brace end attached to the beam.
End of Referenced Element Available when attached to a beam. Designated end (Start or End) of the referenced beam to which the finish end of brace is attached. Applies to the brace end attached to the beam.
Rebar Cover - Top Face Applies to concrete beams only. The rebar cover distance from the column top face.
Rebar Cover - Bottom Face Applies to concrete beams only. The rebar cover distance from the column bottom face.
Rebar Cover - Other Faces Applies to concrete beams only. The rebar cover distance from the column to adjacent element faces.
Estimated Reinforcement Volume Specifies the estimated reinforcement volume of the selected element. This is a read-only parameter that only displays when rebar has been placed.
Enable Analytical Model Displays the analytical model and includes it in analytical calculations. Selected by default. See Disable an Analytical Model.
Dimensions
Length The length of the brace location line. This is a read-only value.
Volume The volume of the selected brace element. This is a read-only value.
Elevation at Top

Indicates the elevation used for tagging the top of the brace. This is a read-only parameter that reports Varies for sloped planes.

Elevation at Bottom

Indicates the elevation used for tagging the bottom of the brace. This is a read-only parameter that reports Varies for sloped planes.

Mark A label created for the brace. Possible use: shop mark. This value must be unique for each brace in a project. Revit warns you if the number is already used but allows you to continue using it. You can see the warning using the Review Warnings tool. See Review Warning Messages.
Phasing
Phase Created Indicates in which phase the brace component was created. See Project Phasing.
Phase Demolished Indicates in which phase the brace component was demolished. See Project Phasing.
Geometric Position
Start Extension Applies to steel braces only. A dimension that adds brace geometry beyond the start end of the brace.
End Extension Applies to steel braces only. A dimension that adds brace geometry beyond the finish end of the brace.
Start Join Cutback Applies to steel braces only. The dimension between the edge of the start end of the brace and the element to which it is connected. Only for the joined start of an element.
End Join Cutback Applies to steel braces only. The dimension between the edge of the finish end of the brace and the element to which it is connected. Only for the joined end of the element.
yz Justification Applies to steel braces only. Either Uniform or Independent. Uniform allows setting the same parameters to both start and end of a brace. Independent allows setting different parameters to start and end of a brace.
y Justification Applies to Uniform justified steel braces only. Specifies the location of the physical geometry with respect to the location line: either Origin, Left, Center, Right.
y Offset Value Applies to Uniform justified steel braces only. The numeric value that offsets the geometry. The distance between the location line and the characteristic point set in y Justification parameter.
z Justification Applies to Uniform justified steel braces only. Specifies the location of the physical geometry with respect to the location line: either Origin, Top, Center, Bottom.
z Offset Value Applies to Uniform justified steel braces only. The distance between the location line and the characteristic point set in z Justification parameter.
Start y Justification Applies to Independent justified steel braces only. Specifies the location of the physical geometry of the start end of the brace with respect to the location line: either Origin, Left, Center, Right.
Start y Offset Value Applies to Independent justified steel braces only. The numeric value that offsets the geometry at the start end of the brace. The distance between the location line and the characteristic point set in the Start y Justification parameter.
Start z Justification Applies to Independent justified steel braces only. Specifies the location of the physical geometry with respect to the location line at the start end of the brace: either Origin, Top, Center, Bottom.
Start z Offset Value Applies to Independent justified steel braces only. The numeric value that offsets the geometry at the finish end of the brace. The distance between the location line and the characteristic point set in the Start z Justification parameter.
