The user wants to import only the assembly nodes using tcin_import utility. (all the component parts are existing in Teamcenter database)
Using the switch "use_existing" validates each part file by loading it in NX, which will impact the performance of importing only the top assembly node in case of big assemblies.
SolutionUsing the switch "-include_c=no" will allow only importing the top node data and it will not validate the component parts as well, which will result in faster import operation.
