Trying to model a lug and pin with the lug being a 3D deformable part and the pin being an analytical rigid surface. I use a Rigid Body constraint to attach a reference point (which will also be used as my loading point in the 2 direction) to the surface of the pin and define contact between the lug hole face and pin face. Continuously getting the following warning regardless of the deformation restraints that I use to fix the non-2 direction restraints and too many cutbacks error. I set the model up exactly the same way in Abaqus Learning Edition and the model runs to completion.

OVERCONSTRAINT CHECKS: 
An overconstraint was detected at node 1 ASSEMBLY_NAME  ASSEMBLY. There are multiple constraints 
applied directly or chained constraints that are applied indirectly at this node. 
A list of nodes and chained constraints between these nodes that most likely lead 
to the detected overconstraint can be printed out to the message file by including 
*constraint controls, print=yes in the input file.
