Once you no longer need a results package, or if you want to save space on your hard drive, you can use the Results Manager to delete one or several results packages from your Revit project.
- Click Analyze tab
Structural Analysis panel 
Results Manager.
The Results Manager dialog opens.
- Select a result package that has been saved to the Revit project, and then click Remove from project.
- Click OK to close the confirmation dialog.
Note: This procedure removes results packages saved in the
Revit project only. To check that a result package is located in the
Revit project only, check that its location in the
Results Manager dialog is set to
in project.
