hi,

yes, I think you are correct. from help doc, this method deletes entire contents of document, returning to default (untitled, empty) state.

Hi,Mr.Liang

 so what about the MainDocument?the doc says it can't be change during the lifetime,what is the difference between the maindocument and activedocument?

in the vs' monitor,the maindocument is the same as activedocument

and another additional question ,not about the api ,i've heard the navisworks 2014 is coming this month?

Hi,

Navisworks is still SDI (single document) currently. The MainDocument is always the same as the ActiveDocument. If  the development of Navisworks is improved to work with MDI(multiple documents) in the future, this will imply that the ActiveDocument may not always reference the same object, like AutoCAD.

yes, as I know.
