I'm trying to figure out this issue with these site surveys and how they come into Revit.
Could someone please take a look at these 2 survey files and tell me what the difference is regarding the 0 elevation? In both files, annotations etc. are at elevation 0, while the contour lines are up at their respective elevations. However, when I link both files into Revit, the Isle file comes in with the annotations at 98.xxx' below Revit's 0 elevation, while the survey.dwg file comes in correct with annotations at Revit's 0, and the contours at the correct height.
Could it have something to do with differences in UCS between the files or something? Something in the Isle file has to be telling it that the actual 0 elevation is 98.xxx feet above where the file says 0 elevation is located.
I have attached both CAD survey files, as well as a Revit file with both CAD files linked in. If you download the files and update the file locations in Revit, you should see how they're not coming in at the same level. The attached image shows the survey.dwg link on the left, coming in correctly with its annotation that reports 0 elevation actually at Revit's 0 elevation. The link on the right shows the Isle Topo file with annotation that reports 0 elevation at some random dimension below Revit's 0 elevation. This throws off all the contour elevations by that value.
