3D objects not shown where their snap points are

[kevin.a.whitten]

Hell All,

This problem has just started to occur and frankly, I'm totally stuck. When I created 3d objects to represents conduits runs in a building, they worked fine. However, when I saved and reopened my file, the objects  are shown in different locations, yet their snap points (endpoints, midpoints, arcs, etc) are shown in the correct location. I have attached an image showing what I mean to clarify. Any help to fix the situation would be greatly appreciated, I am using Autocad 2014 and Civil 3D 2014.
