You can delete any parametric assemblies that you do not use. Note that deleting a parametric assembly cannot be reversed, so a deleted assembly can no longer be used in Tekla EPM.

1. Click the Maintenance ribbon tab.
2. On the menu, select Estimating Maintenance > Parametric Assembly Maintenance.
3. In the Select Parametric Assembly dialog box, select the parametric assembly that you want to delete.
4. Click Delete.
5. To permanently delete the selected parametric assembly, click Yes in the confirmation dialog box.
