Hi,I used the template , working with no problems on 2016Any ideas why this coordinates are not same? I tried to link it first with shared coordinates, but this message appeared:Differing Coordinate Systems '...files do not share the same coordinates, center-to-center positioning wil be used'So i linked again using Origin to Origin and acquired coordinates. And they came lightly wrong as on attached. I moved base point manually, but don't know if it's not going to create later issues.

For 2 models to have shared coordinates and be able to be inserted into the correct position each time using the "insert shared coordinate" tool, then the following steps need to first be taken:1) A model is first created with the correct X/Y/Z coordinates. For me this is always the site model. In this model, I import the survey created by surveyor in AutoCAD (DWG) and I use "Specify Coordinates At A Point" tool to ensure my model's Northings & Eastings (The X/Y Coordinates) are correct and match what is happening on the actual site. I then generate the toposurface to give me a 3D element that correctly represents the topography. I then raise or lower the toposurface so it sits in the correct Z plane. Now a site model is ready.2) Any second model that is created needs to be imported into the first model, shifted to the correct location in the X/Y/Z planes. Then in Revit the user must use the "Publish Coordinates" tool to change the coordinates within the second model to match where it sits within the first model.

If the first 2 steps have not been followed then it is highly likely that inserting the second model into the first using "Shared Coordinates" will result in the second model not coming in at the correct location.Were these steps taken? If not then you need to reject the models and request they be reissued when these steps are taken.
