Joint Issue

[markandcandyingle]

I am trying to learn Joints so I created an example of an idea I have for a project.  I would like to create a hollow cylinder that rotates on two extruded exterior joints and with two hinges attached to a rod.  The rod is grounded.  My problem is that I cannot get the rod centered between the two hinges evenly.  The "two faces" features after selecting the origin (middle) of the rod does not work (all other objects are greyed out).  The attached file is the best I have been able to accomplish.  The rod needs to be evenly spaced but I can only get it to join flush with one of the hinges.  Im close but not quite there!

Hi,

Not sure what you want to do exactly, but check this please, it might help

Sorry forgot the screencast

one possibility is to position a "joint origin" between the linkages.  The trick there is to create an assembly out of the linkages and make them a rigid group so they don't move.  Then place a joint origin between the faces. 

(actually, its possible you can skip the assembly part, and just make a ridged joint between the linkages.  I didn't screen cast it that way, but you might try.  either way, you need the linkages to move together.)

I just tried it.  You can skip making an assembly out of the linkages.  just apply a ridged group joint to them from the assembly menu.  every thing else in the screen cast would be the same.

Thanks LC!  I'll spend some time reviewing the screencast.  The end result of your screencast is what I am trying to accomplish
