I ´ve got one question.
I would like to make my own shift grid for national conversion between new an old datum (and reverse). I ´ve got an xls file with X, Y coordinates and their dX and dY. Is there any chance to make own shift grid in Bentley map or I will need other software.
I have read something about GSB files in GeoCoordinateData (http://communities.bentley.com/products/geospatial/desktop/f/5924/p/53164/123488#123488) but I don't know if those files uses same values (X,Y,dX,dY) or they are completely different.
out of curiosity I tried to search Internet and it seems CNT v2 format seems to be very well hidden secret. Even if I found some link promising format description, a target document did not exist :-(
Probably the only tool I found, which seems be able to create gsb format, is this tool hosted on GitHub. Readme provides good overview of the situation, but it seems even with such tool it's quite a lot of work to prepare source data to be converted to binary gsb format.
