XS_EXPORT_DGN_COORDINATE_SCALE
Category in Advanced options dialog: Export
Use this advanced option to set the coordinate scale to use in the 3D DGN v7 export.
The DGN coordinate scale does not actually scale the model, but changes the model precision. If you set this advanced option to 100, the accuracy is 1/100 mm.
This advanced option is model specific and the setting is saved in the options database.
