Bentley Map used to have a Geodesic Line tool for drawing Great Circles arcs. That tool was removed in Map SS3 along with the entire Coordinate Utilities toolbox. We were told by someone at Bentley that these would be updated and added to MicroStation.
For small scale mapping and analysis the Geodesic Line tool is an essential tool.
Similarly a Range Ring tool that draws geographically correct range rings about a point is also needed.
