You can make the imported drawing visible on any plan through the Visible Objects dialog box. Usually you want to make it visible on the Mesh Input Standard Plan (for defining the floor geometry), and perhaps on some loading plans (for locations of line and point loads). You may choose to turn off some CAD layers if they clutter the drawing. If you happened to bring in an architectural drawing, it is probably a good idea to turn off the furniture. See "Controlling views" for more information on making objects visible or hidden.
