Question

Hej 
 
 I am looking for best practice to deliver 3D CAD files (dgn) to our Client. We do not want to deliver native files with corridors definitions, as there are to many relationships, references, etc. We would like to deliver just the Default-3D model. The problem is that exporting just this Default-3D model will strip OpenRoads Civil Specific Data (Feature Name, Feature Definition, Start/Stop Stations, etc). Same with Copy Fence to File command or merging Default-3D to an external 3D file. 
 
 The solution would be to create imodel where the Civil Business Data is retained but unfortunately linear features that has originally gaps in the native model, once exported these gaps are being healed/closed with a linear segment with no vertexes. 
 I would appreciate any piece of advice.

Hi Adam, 
 
 As far as I know, exporting the 3d model only will have the civil data stripped but elements will retain the same Element ID, so how about using Asset Manager to add Item Types of all the data you need, ie. Feature info, stations, etc. to your 3d Civil elements and then use the Item Type Export Instances tool to export the Item Types out. This will store the Item Type data with the related Element ID. 
 
 You could then export your 3d model out to a 3d CAD DGN and use the Item Type import tool to Import Instances. If all goes to plan, the same Item Type data it had before being "uncivililised" will be reattached. 
 
 I haven't tested this workflow, but should work well in theory.
