Highlight each line of the above panel and insert the appropriate links to the other pages of your tutorial

Highlight the bold line at the bottom of the page that read "Go to Step...". Insert the appropriate link to the next page of your tutorial.

Enter any relevant text, images, and videos in the space under where it says "cloak" below

Now it is time to prepare the connection definitions.  Normally, the program's definitions is able to read the geometry and automatically link it correctly with connections.  However, we have all the types of geometry: Shell (a 2-D plane that has a defined, but not meshed, thickness), a line body (a 1-D body with a defined, but not meshed, cross-section) and a Solid (a normal, meshed, 3D material), and the program does not automatically know how to connect between those things.  Is it a rotating joint, a solid joint, maybe translational?

We will have four types of connections we need to define: 1. Rigid joint to surface. 2. Solid surface to Shell Surfaces. 3. Solid edges to shell surfaces and 4. Rigid Joint to Solid surface.

1. Rigid Joint to Surface.

First, we need to create a Joint Connection:   Right click on Connections and select Insert>Joint.

Now, use the Vertex tool to select the point where the line bodies intersect, "above" the flexure mount and apply it as the "Mobile" Geometry selection.  Then select the face of the flexure mount near the vertex (using the surface select tool) and then apply it as the Reference Geometry selection.

Do this for the remaining flexure mounts, and the center submount.  There should be a total of 9 Joints created from this.

2. Solid Surface to Shell Surface

Hide the Bodies so only the shell model of the subframe closest to the Flexure mount is showing.

Insert a new Manual Contact Region.  Right Click on Connections, Insert>Manual Contact Region.
