I've set my project location (latitude, Longitude and Altitude) to a specific surveyed benchmark on one of our sites.
When I then locate another coordinate marker using ArchiCAD 18's Coordinate Dimension object and set the marker location to use World Coordinates relative to project Location, the World Coordinates give the correct latitude but the incorrect longitude.
I've attached screen shots showing the project Location dialogue and the World Coordinates which who the correct latitude but the incorrect Longitude for the project Location.
Anyone else run into this problem? or - I could be doing something stupid too...you never know
