Hello all,I´m writting my bachelor theses about transforming coordinates from "Gauss Krüger" to "ETRS89.UTM32N".I have tried the transformation with AutoCAD Civil3D.My way trough the transformation was:1. Set the coordinate system to DHDN-GK Zone 4 on the current project. Save project.2. Open a new project, set de coordinate system to "ETRS89.UTM 32N". Go to ModellSpace Planning & Analysis3. Open the Tast Pane (MAPWSSPACE), Add the drawing with Gauss Krüger Zone4.dwg. Then go to the query library and define a new query with all subjects and start drawing.But then a I have the following problem:AutoCAD is saying the it can not open / query the drawing with Gauss Krüger Zone4.dwgDetails: -AECC_COGO_POINT - Referenz 1C7D3            - AECC_COGO_POINT - Referenz 1C7D4            and so on.My current projects just contains cogo points. Is this the problem?Can anybody help my with this problem?I´m buuuusy with writing my theses
