Requesting the ability to Modify a Bentley Map feature in MicroStation.
MicroStation is not able to modify Bentley Map V8i (SELECTseries 3) features directly, due to XFM attribute constraints on the feature.
In order to resolve this issue, use Bentley Map's "Export to MicroStation Elements" command, found in the Command Manager. This tool was implemented for the new XFM data model in Bentley Map V8i (SELECTseries 3). Another option is to use the "Save as..." options in MicroStation, setting the Convert XFM Instances mode to 08.11.09.xx to 08.11.07.xx.
There are more details on using Export or Save as in the Bentley Map Help Documentation.
But it doesn't keep MS levels as all features are copied to seperate level...
It would be better if the individual element(s) was converted to a standard Mstn element with all the attribute info convereted into ECXattributes that can be displayed / queried in Mstn. It sounds like individual elements can be exported... why not on copying 'through; into the active file..?
It would also be good if there was a way to preseve a link back to the original. The elements 'copied' from a CVE Ref are apparently 'proxy geometry' that preserves a link back to its original. Can the CVE mechanism be used to create 'associative' features that can be updated across dgn files?
