I have an issue thats been bugging me all day. I am trying to connect a clevis end from a pnumatic cylinder to a lever arm attached to a pivoting rod. I cannot seem to get inventor to accept the constraint of the clevis pin and pivoting rod mated to the lever arm at the same time without a conflicting contraints error. I analized the DOF's for the clinder and the lever arm and I can see they have the correct rotational freedom to find a solution. I am including a link to download the project folder for anyone that thinks they can help. My ultimate goal is to have a driven constraint for the push rod of the cylinder move the arm, actuating the flap attahed to the pivoting rod.
I am using 2013 on a MBP running VMware.
Thanks in advance!

Side Asm.iam needs to be set to Flexable.
T1W-13E100000N_Arod.prt needs to have the Flush constraint set to be set to Limits.
I would probably uncheck Adaptivity for parts that are adaptive.

That got it, thanks! I had been using flexible before but had trouble getting the constraints to mesh in other areas. I thought for some reason that flexible wouldn't be necessary to find the static solution but I was wrong. I set limit on the flush constraint (something ive never done before) and I can manipulate the lever to its limits like I want.
The issue I have now is how to drive the motion of the assembly, I can create a driven constant between the rod and the cylinder but that has no importance at the top level since all higher order constraints are suppressed. If I create constraints on the components at the top assembly level my model becomes over constrained. How can I simulate the assembly with out manually manipulating the geometry?
Thanks again for your help
