NW Properties is a modeless dialog. Open the dialog and select something in your model. The dialog will automatically fill in to show the selected object's properties.

The supplied installer can be used to install and uninstall the product. The product is installed in the Autodesk® Navisworks® folder ... C:\ProgramFiles\Autodesk\Navisworks <product>\Plugins\.

We use a custom installer to be consistent with our other installers that supply a 14 day trial and to manage the xaml file required for creating our Tab.
