Bentley Map V8i provides Map Finishing tools which were formerly available via CADscript.
To access the Map Finishing tools in Bentley Map V8i, initialize your DGN in the msgeo_mapfinishing workspace.  

Note:  The Advanced Map Finishing tools are discontinued subsequent to the V8i product series and are not available in OpenCities Map CONNECT Edition and support for Map V8i has expired as of 2022. 
Existing installations of stand-alone Bentley Map with Advanced Map Finishing will function when a licensed OpenCities Map CONNECT edition installation is available on the same machine. 
In this case, the same license is used.  You are able to run Map V8i (SELECTseries 10) and Map CONNECT simultaneously without incurring additional license fees.
