Hi Ryan,

In SpaceClaim, go to the Prepare tab and click the Share tool. That will search for edges to merge with adjacent edges or faces. The color of the edge changes to purple when it is shared.  This is much like what you will see in Meshing with a Mesh Connection, the color of the element edges is purple when three elements share an edge (like a T-intersection).

You can put a movie file inside a zip file and attach that as long as the file size is < 120 MB. You can always upload to YouTube like I do.

You can share your entire Workbench Project by making an Archive .wbpz file and that can be attached to Posts (but not .wbpj files).
