The Align node (the Align sheet in the StructFrameConnections.xls workbook) defines the align frame connections that are available. The align frame connection places the member end at the intersection of three surfaces that you define.


Defines the name of the frame connection. This is the name that appears in the software when placing a member system in the model.


Specifies the align frame connection definition macro SPSFrameConnMacros.Align.

Side Justification

Select the side of the plane on which to place the member.

  • None - Aligns the member axis so that it is placed on the surface.

  • Seated - Sets the member on top of the surface. The selected Orientation Side is nearest the surface.

  • Center - The center of the cross-section is placed on the surface. The center is calculated by the top-bottom, left-right bounds of the cross-section shape.

  • Flush - Uses the alignment surface's top and bottom extent to position the supported member. The supported member typically lies within the body of the alignment plane with one edge of the member flush with the alignment surface but can be offset.

Orientation Control

If On, the member angle is controlled by the Orientation Angle value defined for the Align frame connection. If Off, you can set the angle of the member independently of the align surface by using the Rotation property for the member part.

Orientation Side

Specifies the side of the supported member's cross-section that is mated to the alignment surface. You can specify Top, Right, Bottom, or Left. Edges of typical section shapes are shown in the figure.

Orientation Angle

When Orientation Control is On, this angle is added to the selected Orientation Side to rotate the member. If the Align frame connection is used on both ends of the member and you define a different angle value for each end, the angle defined at the start end of the member is used.


Reflects or mirrors the cross-section of the supported member about a plane perpendicular to the supporting member side. An example of when to use this option is when you place a supported member with an angle cross-section using the left edge option and you want the angle facing the other direction.

Extend Distance

Specifies the offset distance from the bounding surface along the member's axis.

Side Clearance

Specify the offset distance perpendicular to the align surface to place the member axis.

Lateral Distance

Specifies the offset distance in the plane of the align surface to place the member axis.
