When CivilGEO’s software starts up, a new, empty project Map View is created using a local coordinate reference system (CRS). However, to display external data correctly on the Map View, a projected CRS should be assigned to the Map View.
A local coordinate reference system is well suited for simple engineering models that contain only basic geometry that is not georeferenced. Importing an external engineering model without an assigned CRS will cause the imported model to be assigned a local CRS. Similarly, importing any external data without a corresponding coordinate system will cause the data to be assigned a local CRS.
See this article for information on georeferencing an external engineering model to a location on the map.
