Beginning with the Bentley Map V8i (SELECTseries 3) release, the referential integrity of XFM feature instances (graphic and non-graphic elements) is protected when design files are opened in a pure MicroStation session. This additional level of data protection was implemented after careful consideration of several technical support incidents where customers edited their Bentley Map produced data in other products (e.g. MicroStation) without Bentley Map present, resulting in unexpected data corruption.
Example of reported design file editing workflows and resulting data problems included:
As a result, if Bentley Map is not use to edit the design file, XFM feature instances cannot be manipulated to:
The Bentley Map product team is working to gather functional requirements from numerous customers who have existing workflows that require "limited" editing or manipulation of Bentley Map data in scenarios where Bentley Map is not present. The objective of this effort is to expand what type of editing or manipulation can be done of data when Bentley Map is not present, while at the same time preserving the data integrity.
