You can set the active view for an asset using the Asset Editor or Attribute Editor. The active view defines the interface for the asset in the windows and editors of Maya.
Before you set the view, your asset must have a template assigned that includes views. (See Assign a template to an asset and Add a custom view to an asset template.)
