It was there in MicroStation GeoGraphics and also BentleyMap XM. Where has it gone? I understand that assigning Geographic Coordinate Systems has been moved to MicroStation V8i anden-USTelligent Community 12https://communities.bentley.com/thread/60748?ContentTypeID=1Fri, 12 Jun 2009 16:01:33 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:ba256ca6-4514-4268-9119-e13db708c42cFrank Klein<p> This I like to know, too. </p> <p> I'm living in Germany and we have a lot DHDN &quot;local&quot; coordiante systems that has to be shifted with&nbsp; </p> <p> 7-Parameter Bursa Wolf <strong>to be +-0.05m</strong> <strong>accurate</strong>. Shift to ETRF89/ETRS89 projection UTM. </p> <p> So where are the datum-editor and ellipsoid-editor gone and when will they return? </p> <p> (I was looking in PowerMap V8i) </p> <p> &nbsp;Frank </p> <p> &nbsp;PS: The deliverd DHDN GCS in V8i are for large scale maps and not accurate enough for +-0.05m accuracy and local land surveying. </p><div style="clear:both;"></div>
