Since the introduction of the V8i generation of applications, iModel has been the best way to package and share multi-discipline models. They are an immutable representation which retains provenance, perfectly suited for sharing designs with project partners for bids and milestone reviews. The introduction of the new generation of iModels, and the advancement of the iModel.js platform to its version 1.0 release, is a perfect opportunity for a quick reintroduction to this capability.
The iModel technology is of two primary types: the new generation of iModels and the I.DGN. Both have the advantage of normalizing all property data and geometry to make it more efficient and readable in a consistent way by any consuming application. Which version you need depends primarily on how you need to structure your data and how you wish to use the iModel: whether you need to keep separate i.DGN’s for each reference file or you need a packaged iModel that would contain any of the references in one packaged file. The .iModel 2.0 format acts as an entry point to the exciting new iModel.js ecosystem which enables iTwin cloud services and mobile applications.
The capability to publish an iModel is found in Bentley View so it is available at no charge for anyone. Bentley View opens a vast array of common file types, making it an ideal way to package and share design data. iModel publishing is also available from MicroStation, PowerDraft, and nearly every other Bentley desktop application.
This will create a single package for multiple .i.dgn files. Selecting this option will enable rest of the controls in this section.
The file’s location is displayed in the Message Center.
The development of iModel.js continues at a fast pace, therefore, please visit the project site frequently.
We hope this blog article is helpful and look forward to hearing about how you put iModels to work.
