Structural Column Instance Properties

Modify structural column instance properties to change level offsets, geometry justification, phasing data, and more.

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

Name	Description
Constraints
Column Location Mark	The coordinate location of a vertical column on the project grid.
Base Level	Constraining level of the column base.
Base Offset	Offset of base from base level.
Top Level	Constraining level of the column top.
Top Offset	Offset of top from top level.
Moves With Grids	Changes the vertical column constraint to the grid. See Lock Columns to a Grid.
Move Top With Grids	Constrains the top endpoint of the slanted column to the grid.
Move Base With Grids	Constrains the base endpoint of the slanted column to the grid.
Top Cut Style	Either Perpendicular, Horizontal, or Vertical. Specifies the cut style at the top of the column when unattached to a reference or element.
Top Extension	Offset of the top of the column when unattached to a reference or element.
Base Cut Style	Either Perpendicular, Horizontal, or Vertical. Specifies the cut style at the base of the column when unattached to a reference or element.
Base Extension	Offset of the base of the column when unattached to a reference or element.
Column Style	Either Vertical, Slanted - End Point Driven, or Slanted - Angle Driven. Specifies the slant style of the column which enables type specific modification tools. See Slanted Column Manual Adjustment Tools.
Base Geometry Alignment	Either Location Line, Top of beam, Bottom of Beam, or Center of Beam. Specifies the working point along an attached beam to which the centerline of a slanted column adjusts at its base.
Top Geometry Alignment	Either Location Line, Top of beam, Bottom of Beam, or Center of Beam. Specifies the working point along an attached beam to which the centerline of a slanted column adjusts at its top.
Base is Attached	Read-only parameter specifying that the base of the column is mid-joined to a beam or attached to a structural floor or roof.
Attachment Justification At Base	Either Minimum Intersection, Intersect Column Midline, Maximum Intersection, or Tangent. Specifies the degree of cutback or tangential justification at the base of the column at the join.
Offset From Attachment At Base	Offset of the base of the column from the mid-joined beam or attached elements.
Top is Attached	Read-only parameter specifying that the top of the column is mid-joined to a beam or attached to a structural floor or roof.
Attachment Justification At Top	Either Minimum Intersection, Intersect Column Midline, Maximum Intersection, or Tangent. Specifies the degree of cutback or tangential justification at the top of the column at the join.
Offset From Attachment At Top	Offset of the top of the column from the mid-joined beam or attached elements.
Room Bounding	Changes column constraint to room-bounding conditions.
Materials and Finishes
Structural Material	For more information, see Change the Physical Properties of a Material.
Structural
Top Connection	Applies to steel columns only. Turns on the visibility of a moment or shear connection symbol. The symbols are visible only in elevations and cuts parallel to the main axis of the column in coarse view.
Base Connection	Applies to steel columns only. Turns on the visibility of the base plate symbol. The symbols are visible only in elevations and cuts parallel to the main axis of the column in coarse view.
Enable Analytical Model	Displays the analytical model and includes it in analytical calculations. Selected by default. See Disable an Analytical Model.
Top Attachment Type	Either Distance or Ratio. Determines if the top join of a slanted column is measured as a distance or a ratio of the length of the beam.
Top Attachment Distance	Distance from the referenced end of the top attached beam to the join location on the slanted column.
Top Attachment Ratio	The ratio of distance from the referenced end of the attached beam to the top join location on the slanted column to the total length of the beam.
Top Attachment Referenced End	Either Start or End. Specifies the end of the top attached beam from which to calculate distance or ratio.
Base Attachment Type	Either Distance or Ratio. Determines if the base join of a slanted column is measured as a distance or a ratio of the length of the beam.
Base Attachment Distance	Distance from the referenced end of the base attached beam to the join location on the slanted column.
Base Attachment Ratio	The ratio of distance from the referenced end of the attached beam to the base join location on the slanted column to the total length of the beam.
Base Attachment Referenced End	Either Start or End. Specifies the end of the base attached beam from which to calculate distance or ratio.
Rebar Cover - Top Face	Applies to concrete columns only. Sets the rebar cover distance from the column top face.
Rebar Cover - Bottom Face	Applies to concrete columns only. Sets the rebar cover distance from the column bottom face.
Rebar Cover - Other Faces	Applies to concrete columns only. Sets the rebar cover distance from the column to other 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.
Dimensions
Volume	Volume of the selected column. A read-only value.
Identity Data
Comments	User comments.
Mark	A label created for the column. Possible use: shop mark. This value must be unique for each element 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. For more information, see Review Warning Messages.
Phasing
Phase Created	Indicates in which phase the column component was created. For more information, see Project Phasing.
Phase Demolished	Indicates in which phase the column component was demolished. For more information, see Project Phasing.
