GearHeads Corner

A gear pair that I had created using auto train is now failing to run when simulation is invoked. I am sure it is due to linking errors I have created while screwing with the design. I have seen the video which explains how to use the linkage buttons to fix this problem but, I can?t remember which one it was. I do remember that when watching the video, for the first time, I was surprised that the subject was being dealt with considering what the title implied was being covered.  I need to re-watch it. Can some one share with me the name of the video in question?

Also, is there a cross reference that would associate buttons with videos? There is some information in the PDF document associating some functions with videos but a lot of references are missing. Short of watching all videos I am not sure what to do.

Hi Bob:

  I think the video your refering to is https://www.youtube.com/watch?v=Z72IK0jn0nQ

  In general, if you click on any gear its linkage will be shown.. what it drives..

So, starting from the master , analyse your train. Turn on sim and watch what moves. If the master turns, good, does the next one turn..if not,
its linkage is busted, so click on the master and see what its linked to, select the add link and if the gear you want it to drive doesnt show up,
then cancel and look at the gear you wanted to show up and see what its driven by and repair that link.

    The Add and remove linkage buttons will be all you need, just remember the golden rule of linkages,
                " Any gear may drive multiple gears, but may only be driven by one. "

  So if you click on a gear and select add linkage, and the gear you WANT to drive isnt in the list, its because its already
being driven by another. Find and kill that linkage, and the gear you wanted will then show up when you select
add linkage to the gear you originally wanted to drive it from.

  This all sounds complex, but youll find its pretty trivial when you get going..
