I'm trying to create custom coordinate systems but I can't get the edit Coordinate System Settings option to appear when I'm in the library. I'm using v8i and Inroads. Do I need OpenCities or is there another program?
MicroStation Update 14 provides the capabilities to edit and create Custom Coordinate Systems now, so no, Map is not the only program that you can do this with. The MicroStation Help file has the details: https://docs.bentley.com/LiveContent/web/MicroStation%20Help-v16/en/GUID-08E26754-2304-1002-2E96-BFFC28F4214F.html
Bentley Map V8i remains the name for the V8i editions. OpenCities Map CONNECT Edition is the name for the CONNECT Edition products.
