To import a data model into Linear Draft, open a new blank MicroStation file and select ‘Data Import’ from the Linear Draft toolbar. A file explorer window will be displayed, browse for a .ld model and select it from its saved location and click 'Open'.
Browse for model and select it from its saved location. Once located, click ‘Import’.
Linear Draft will then import the model into your CAD application. The import may take a few minutes depending on the size of the model.
Once the model has finished importing, you may then need to re-reference in any information that will not have been carried across from the export (such as a track alignment file).
