Analytical Member Instance Properties

Modify instance properties to change a member's level constraints, structural role, association with physical counterpart, and more.

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

Name	Description
Constraints
Highest Associated Level	Specifies the highest associated level of the selected analytical member or panel. You can choose a different value for this parameter only while creating an analytical member using the Top Point Definition command.
Lowest Associated Level	Specifies the lowest associated level of the selected analytical member or panel. You can choose a different value for this parameter only while creating an analytical member using the Top Point Definition command.
Materials and Finishes
Structural Material	Specifies a material for the element which may impact structural analysis. It can also control 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.

Physical Material Asset	Specifies the physical asset of the material if one is defined for the selected material.
Structural
Structural Role	Specifies the structural role of the element, selected from the drop-down list.
Section Type	Specifies the structural beam or column family type loaded in the project. The list of structural types is filtered based on the Structural Role.
Section Shape	Specifies the structural section shape family category of the element. The section shape creates additional dimensions and parameters for the element.
Cross-Section Rotation	Controls the orientation of the cross-section. The cross section representation is controlled by a sub-category of the analytical member called Cross Section and is shown in the model as its exact shape (if a Section Type is defined) at the mid-point of the analytical member.
Analyze As	Specifies element specific conditions used by external applications to determine appropriate analysis. Depending on the element, selection options include Hanger, Gravity, or Lateral analysis.
Has Association	Specifies whether the element has a counterpart in the project or not. A counterpart is an element belonging to an associated representation (physical or analytical) than the selected element.
Releases / Member Forces
Start Release	Specifies the end release condition: either Fixed, Pinned, Bending Moment or User Defined. User Defined allows you to enable/disable each of the end release conditions.
Start Fx	The translational release at the beginning of the member along the local x-axis. When selected the degree of freedom is released and the force is not available.
Start Fy	The translational release at the beginning of the member along the local y-axis. When selected the degree of freedom is released and the force is not available.
Start Fz	The translational release at the beginning of the member along the local z-axis. When selected the degree of freedom is released and the force is not available.
Start Mx	The rotational release at the beginning of the member along the local x-axis. When selected the degree of freedom is released and the moment is not available.
Start My	The rotational release at the beginning of the member along the local y-axis. When selected the degree of freedom is released and the moment is not available.
Start Mz	The rotational release at the beginning of the member along the local z-axis. When selected the degree of freedom is released and the moment is not available.
End Release	Specifies the end release condition: either Fixed, Pinned, Bending Moment or User Defined. User Defined allows you to enable/disable each of the end release conditions.
End Fx	The translational release at the end of the member along the local x-axis. When selected the degree of freedom is released and the force is not available.
End Fy	The translational release at the end of the member along the local y-axis. When selected the degree of freedom is released and the force is not available.
End Fz	The translational release at the end of the member along the local z-axis. When selected the degree of freedom is released and the force is not available.
End Mx	The rotational release at the end of the member along the local x-axis. When selected the degree of freedom is released and the moment is not available.
End My	The rotational release at the end of the member along the local y-axis. When selected the degree of freedom is released and the moment is not available.
End Mz	The rotational release at the end of the member along the local z-axis. When selected the degree of freedom is released and the moment is not available.
Member Forces	Specifies the internal forces at the ends of the analytical models of columns, beams, and braces. This data communicates load information for both documentation and connection fabrication.
