The question is:- there is a large Solidworks assembly (assume almost more than 6k parts) and has a long model tree. there is a part or pars which are under defined and is assembled in some of the sub-assembly of the sub-assembly of the sub-assemblies and it is very difficult to explore one by one all the tree sub-assembly. As well as it is time consuming too. Now in this case how to find under defined parts in a single click ???? Or is there any way rather than a common answer the (-) sign for under defined pars/assy'/sketch???
