Using Convert Object to Viewport command when I convernt a closed polyline to a viewport and then select that viewport in the Properties dialog box CAD shows 2 objects selected one is the viewport and the other one is the polyline itself. I think after converting the polyline to viewport it should be a single object only and not two.
Secondly if their are 2 objects then why the viewport is not visible and only the polyline is visible. Is the viewport some invisible entity that we cannot select separately without selecting the polyline. If they are two objects how to separate them from each other.
