Question:

When I publish an i-model from MicroStation CONNECT v10.04.00.46, and then open the i-model in OpenRoads Navigator CONNECT, I get one of the following error messages:

“Unable to open file”

“The i-model you are trying to open is not supported by this version of Navigator. Use MicroStation CONNECT Edition Update 3 or a newer version of your publishing application to republish the i-model.”

Why is this, and how do I fix it?

Answer:

MicroStation CONNECT comes with a newer DgnDb i-model Importer, v01.05.08xxx.x, that creates a 0601 i-model. OpenRoads Navigator will only read 0505 i-models that are created from a previous DgnDb i-model Importer v01.05.07.xxx.x.

To be able to open an i-model in OpenRoads Navigator CONNECT v10.00.01.39:

1. Uninstall the Bentley DgnDb i-model Importer 1.5 x64 (it is version 01.05.08xxx.x)
2. Download the previous version, ItgDgnDbImporter1-5-7-9_x64.zip, here: ItgDgnDbImporter1-5-7-9_x64.zip
3. Install the previous version by launching, ItgDgnDbImporter_x64.msi.
4. Create another i-model within MicroStation CONNECT.
5. Open the i-model in OpenRoads Navigator CONNECT.
