Category in Advanced options dialog: Export
Set this advanced option to
TRUE to enable the
use of local ID numbers in 3D DGN export. Every exported part gets a unique ID number
starting from 1. The ID is saved as a user-defined attribute, and the same ID will
be used in consequent exports. The default value is TRUE.
This advanced option is model specific and the setting is saved in the options database. Reopen the model to activate the new value.
