There are a lot of threads and posts about autostruts and robotic parts. Some of them deal with autostrutting, and others with wheels having locked autostruts.

If you turn on "Visualize Autostruts" as described in this thread, you'll see some... interesting results. Note the line does not go to the heaviest part
