Merge Common PSHELLs

Merge Common PSHELLs

FEM output for assemblies containing repeated parts with common thickness/material midsurface properties generates duplicate NASTRAN property cards.  In large assembly models, the number of duplicate PIDs becomes large and merging them to facilitate thickness variation of a part via editing the bulk data becomes cumbersome.  Request enhancement to merge these PSHELLs across common parts (e.g. all instances of PRT0001 should reference a common PID) or provide option to do so.  Example mat/prop output for a pattern of two common parts of thickness .025" in an assembly is as follows:
