Unload lines
If you encounter memory problems when expanding a structure, you can unload selected lines to free memory manually.
Procedure Right-click the line below which you want to unload lines (for example, a subassembly) and choose Unload Below. Teamcenter displays the Unload Below dialog box. Click Yes to continue. Teamcenter unloads all the lines below the current selection from the current session.
