We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Here is the structure shown as shells and lines.

Thick shells and beams are shown here.

The problem occurs at several locations in the model, but for this discussion, we'll just focus on a few.

I'll provide a few examples for our discussion.  Here is a table depicting the connections shown below.  17 and 23 interact.  37, 41, 46, 47, 51, and 52 interact.

Joints 17 and 23 conflict and are shown in the following images.

Joints 37, 41, 46, 47, 51, and 52 conflict and are shown in the following images.

As you can see, the connections are quite tangled.  But this is how things are connected in reality.  I need to come up with an alternative method to connect the pieces.  Can you elaborate on "connection body with three legs?"  Is this a set of small lines that are joined with Shared Topology, and have separate joints at each end for connection to the assembly?
