To Repeatedly Make the Same Modifications

Create a selection set of several Structural columns.
Key-in STFMODIFY ATTRIBUTES CLASSIC.
The Modify Structural Attributes (Classic) tool settings window opens.

Note: Initially, when the Modify Structural Attributes (Classic) is first used, its tool settings are all disabled.
Modify the following attributes on the General tab: Section, Placement Point and Rotation Angle. Enter a data point to accept the changes.
Create a selection set of several Structural beams.
Key-in STFMODIFY ATTRIBUTES CLASSIC again. The Modify Structural Attributes (Classic) tool settings window opens with the same changes to the Section, Placement Point and Rotation Angle settings.
Note: The selected Structural beams were placed using different settings for Section, Placement Point and Rotation Angle. Those values were ignored in favor of retaining the previously used settings values regardless of the Structural attributes on the members being selected for modification.
