How to remove Vector3Value Via Command Bar

Name is OriginalSize it is under a part and Under workspace… Any help pls

To change the value:

workspace.part.OriginalSize.Value = Vector3.new(1, 1, 1)

To delete the value instance:

workspace.part.OriginalSize:Destroy()

This should be in #help-and-feedback:scripting-support.
Why do you have to use the command bar? More context on your problem?
