Process Overview: Creating a Multi-Component Structural Member Using Multiple Segments
(Rigid Frame)
Use this example to create a rigid frame, a multi-segmented structural member created from multiple shapes that
transform at each vertex of the structural member path.
To create the rigid frame, you convert a multi-segmented polyline to a structural member and assign different start and
end shapes to each segment of the member as components in the design rules of the rigid frame style. A series of nodes
correspond to the start point, vertices, and the endpoint of the member path. By assigning different shapes to segments
between nodes on the member path, the rigid frame transforms from one shape to several shapes along its path.
Assign shapes to the rigid frame member relative to the start of the member. The start point is defined as Node 0. The
first vertex of the member is defined as Node 1, the next vertex is Node 2, and so on until the endpoint of the member,
which is defined as the end node.
NOTE If you assign shapes relative to the end of the member, the endpoint of the member is defined as Node 0.
Identifying nodes on the member path
Creating the rigid frame
The process of creating this rigid frame has seven steps:
Step 1: Create two styles in the Structural Member Catalog that contain the shapes that transform over the path of
the rigid frame.
