Topographic is not showing in project .

When i use the toposurface tool in site plan and 3D . This is not showing in these tabs . in Level 1 is showing . I check the view range and visual graphics for topographic.

The problem can be related to View Range (for only the site plan) or Visial Visibility (VV) settings. 

Please go to 3D view and click on VV, On the opened window, you should find topography and control their visibility. If The visibility is open, you can control (if the object's source is a link file) Revit link title. If the link visibility is closed you can not the object.  If all of the control is okay, I see that you use realistic view graphics for 3D View, maybe your graphic cards are not enough, and therefore you cannot see some objects. Therefore you should change as the hide line graphic and please control the object again.
