Why do I get the following message when after using the Extract From Graphic command?
The workspace that the dgn is opened in does not have either the SUDA_SEED_FILE or SUDA_SEED_MODEL variables configured properly.
In a Bentley workspace, this variable is set in the _Civil Default Standards (Imperial and Metric) cfg's. By default they are found here: C:\ProgramData\Bentley\OpenRoads Designer CE\Configuration\Organization-Civil and defined as follows below.
