My client needs to export my SS2 .ird into SS4 Open roads in order to then export the model into their staking softwareen-USTelligent Community 12https://communities.bentley.com/thread/391689?ContentTypeID=1Wed, 16 Nov 2016 01:00:09 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:af0beb48-1332-4471-b4a7-842ebdf21344mlemieuxI presume you&#39;re using geopak ss2 since you mentioned &quot;corridor modeling&quot;. If so, then your plan graphics are saved as alignments in the alg file in your rddbs folder. These alignments will need to be imported as civil geometry in a dgn file to work with ss4 modeling.<div style="clear:both;"></div>
