Hi. I have an imported from VWX stage in a drawing. hen I zoom out I get large chevrons on the DS roof. When I zoom in they disappear. When I get into the imported stage I can't select the objects to find out what, or if, class they are on to turn off. They're only on the DS roof truss. They are a noticeable obstruction when exported to PDF. Does anyone know how I could turn those off? Pics attached.
