When I am drawing my duct, I end up selecting something that is on the floor below, which in turn gives me an error. How do I keep this from happening? When I am drawing on the 3rd floor, I don't want to be selecting something on the 2nd floor.</P> Thu, 27 Oct 2011 19:28:38 GMT https://forums.autodesk.com/t5/revit-mep-forum/different-level-selection/m-p/3207722#M82735 CarrieHoffman02 2011-10-27T19:28:38Z https://forums.autodesk.com/t5/revit-mep-forum/different-level-selection/m-p/3207894#M82736 <P>A&nbsp;couple of things. Is your view range below the floor? Do you have a view defined in your underlay parameter?</P> Thu, 27 Oct 2011 20:56:17 GMT https://forums.autodesk.com/t5/revit-mep-forum/different-level-selection/m-p/3207894#M82736 Anonymous 2011-10-27T20:56:17Z https://forums.autodesk.com/t5/revit-mep-forum/different-level-selection/m-p/3207904#M82737 <P>The View Range is set to the associated level at 0. However the floor below is in the Underlay parameter. Does that need to say none or the level I am on?</P> Thu, 27 Oct 2011 20:59:31 GMT https://forums.autodesk.com/t5/revit-mep-forum/different-level-selection/m-p/3207904#M82737 CarrieHoffman02 2011-10-27T20:59:31Z https://forums.autodesk.com/t5/revit-mep-forum/different-level-selection/m-p/3207990#M82738 <P>&lt;none&gt; and your problem will go away.</P> Thu, 27 Oct 2011 21:39:15 GMT https://forums.autodesk.com/t5/revit-mep-forum/different-level-selection/m-p/3207990#M82738 Anonymous 2011-10-27T21:39:15Z
