Details
'Rules' folder is missing in the following location of NX11
%UGII_BASE_DIR%\UGROUTE_ELEC\
However ugroute_elec_metric.xml file refers some files available in "Rules" folder
Solution
TCL design rules are no longer supported for routing, hence the references to the rules are removed in NX12 application view file
