Has anyone ever had a problem with the daylighting polylines. As in I selected my surface, then I selected Create Single, then selected my polyline, then the computer shows the phantom x's for where the daylight line is at. Then I need to create the polyline for where the daylight lines is at. So I selected Daylight Polyline and nothing happens. I pretty sure it's suppose to create a polyline. But has anyone had this happen and what suggestions do you have. Thanks
