I have entered topography levels into Revit 2017. When I go to the Site Plan however all but one contour (14500) is displayed. I'm not sure why this error is occurring. I have checked the the Site Settings and the range is greater than 14500. I have then gone in to see if I can edit the surface, this is when I noticed that the other contours dots are all connected by a line however the 14500 contour while I can see the dots for some reason it hasn't been connected together. Can anyone please advise how I can correct this?
