The ug_assy_build.exe utility is for unmanaged mode. Creating the assembly using the utility then using "%UGII_BASE_DIR%\ugmananger\ugmananger_clone" to import the assembly is viable a solution.
Jpetach,
Thank you for the answer. Our issue is like this.
We have a list of part numbers. These parts are already exisits in Teamcenter. We need to build an assembly file in Teamcenter with these partnumbers.
Is there any utility or tool for this?
