Having only just upgraded to Architectural 2016, I imported a plan from my previous Architectural 10 and found the Selection Cursor paralleled with a blue circle with 2 small blue 'ribbons'. At the same time, 2 sall semi transparent circles seem to be showing some kind of Srrors, but I cannot find any action that will either show me the Errors, or eliminate the circles and the blue symbol next to the Selection Tool. Any helpful ideas, please?
