Identical Hydraulic Cylinders Overdefining Assembly

Hello,

I have a weldment to which I am mating two instances of the same subassembly (a hydraulic cylinder). In the hydraulic cylinder subassembly I have a concentric mate between the rod and barrel, and a limit distance mate between the piston and barrel.
When I mate the barrel end of these subassemblies (set to flexible) in my weldment assembly, everything is fine. The problem comes when I try to mate the rod ends. Each rod is connected to the same plate which slides linearly on the weldment. When I mate the first rod to the plate, everything is still fine, i.e. I can drag the plate and the rod will come with it, and the limit distance mate in the subassembly is obeyed. However when I try to mate the second rod, I get the "overdefine assembly" error, and a whole bunch of mates turn to that pale green color.

I am on SW2006 SP0

Any thoughts? Thanks.

- Chris

I thought SW06 had changed this, but in previous SW versions, a different config was required for each instance of an assy if flexible assys were used.

I think the Limit mate is "limiting" this functionality.

SWx 2005 removed the need for multiple configs when using flexible sub-ass'ys, but I have only used it with out any mate limiting the flexible motion.
 
MElam is correct. You the limit mate in the cylinder assembly that is causing the problem.
