An i-model is a V8-format DGN file published from an original design file. It contains both graphical and business/component information from the original file. The graphical information is converted to a simpler, more efficient representation in the i-model, and the business/component information is converted into a common form in the i-model that does not require access to the original project workspaces or connections to external project databases.
The Bentley i-model Composition Server for i-models extension of Bentley Automation Service is used to define and run jobs that automate the publishing of i-models from your source documents in ProjectWise.
There are three types of i-models you can create:
Bentley i-model Composition Server for i-models uses Bentley i-model Composer to create published and packaged i-models, and uses Navigator Mobile Publisher to create mobile i-models.
Every job, whether or not it creates packaged or mobile i-models, will first create a published i-model for each CAD document explicitly called into your input set. If a job is configured to only create published i-models, then the published i-models will be checked in to ProjectWise at the end of the job, in the same folder as the original file. If an i-model of the same name exists in the original folder, the new i-model will automatically overwrite the old one. The options to create packaged i-models and mobile i-models are both off by default. If you turn on either of those options, you then have the option to not check in the published i-models that get created by the job.
When defining the job:
