Can I use the CIVIL_iMODEL_INCLUDE_ICM workspace variable to default the settings in the Create ICM command?
This configuration variable is used ONLY by the Publish i-model tool in the MicroStation (or Power product) File>Publish i-model… command. This i-model, with ICM data embedded, will be used by the OpenRoads Navigator app.
When the Publish i-model tool is run, it checks this variable to determine whether additional civil metadata (such as linear referencing along alignments) should also be copied into the i-model from the Civil Model. If the variable does not exist, then the icm data (i.e. civil metadata) is not embedded into the i-model. If the value is non-zero as noted below (1,2,or 3) then a temporary icm file is created and embedded within the i-model file.
If the user needs an icm file for export to Trimble Business Center, they will need to run the Model Interoperability>Create ICM tool separately from the Publish i-model tool.
From the Civil Tools help document:
Set to 1 for Design Models only
Set to 2 for Terrain Models only
Set to 3 for both Design and Terrain Models
