Beam System Instance Properties

Name Description
Constraints
3D Creates a non-planar beam system in which the elevation of a beam is defined by its sketch lines. See Creating a 3D Beam System.
Elevation The vertical offset of beam system beams from the beam system work plane.
Work Plane This is a read-only value that is dependent on the work plane where the element was placed.
Pattern
Layout Rule Rules for beam spacing. See Beam System Layout Rules and Patterns.
Fixed Spacing The space between beams. This parameter is only accessible for certain values of the Layout Rule parameter. See Beam System Layout Rules and Patterns.
Centerline Spacing The distance between beam centerlines. This is a read-only parameter.
Justification Specifies the starting location (beginning, end, or center) of the beam system in relation to the selected boundary.
Beam Type The structural framing type to be used for creating beams in a beam system.
Identity Data
Tag new members in view Specifies the view in which to display new beam elements added to the beam system. See Modifying Beam System Tags.
Comments User comments.
Mark A label created for the beam system. 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. See Reviewing Warning Messages.
Phasing
Phase Created Indicates in which phase the beam system was created. See Project Phasing.
Phase Demolished Indicates in which phase the beam system was demolished. See Project Phasing.
