I'm using node to node Tie constraints between corresponding nodes, but this error appears : For *tie pair (assembly_s_surf-15-assembly_m_set-142_cns_), adjusted nodes with very small adjustments were not printed
Have you tried merging two part instances? Please note that when you merge two part instances, it will create a new part and with the same section assigned. You need to reassign the sections (solid and beam) to the newly created part.
Based on your description of the problem, i have created a simple example. Please have a look at the model and let me know if your requirement is something else.
