For the selection of not properly closed areas (outline loops) in a drawing you can use the Map+Civil command MAPCLEAN. If the outlines are separate polylines, you can perform the analysis of closed areas also in the plain AutoCAD.

You can select the not properly closed (open) polylines in your DWG drawing using the QSELECT command. Choose the "Object type" to Polyline, in the "Property" list pick Closed and set the "Operator" and "Value" to = No.

Please note that this checks the internal polyline property only, not the geometric characteristics - you can have a perfectly closed polyline (geometrically) with the Close-property set to False.
