This Technote describes the process by which a user can export their model to an i-model file. It assumes Bentley WaterCAD, WaterGEMS or HAMMER V8i (SelectSeries 3).
When installing WaterCAD/GEMS or HAMMER, the i-model publishing engine shows as a dependency on the download page.
- It is portable.
- It is read-only.
- It can be viewed by users that do not have WaterCAD/GEMS or HAMMER. - The topology, as well as the attributes and results (for a particular time-step) can be viewed in MicroStation, ProjectWise, Navigator and Bentley View. Since Bentley View is free, i-models provide a way for anyone to easily view data and results for a WaterCAD/GEMS or HAMMER model file. Here is a link to Bentley View http://www.bentley.com/en-US/Products/Bentley+View/
- The file name for an i-model is filename.i.dgn
The i-model publishing engine shows as a prerequisite on the download page for hydraulics and hydrology products because it was an appropriate place to put the download or the i-model publishing engine to make it easy to find if it was something that was desirable for the customer to download. It is only necessary if you intend to publish i-models. If you have no need to publish i-models you DO NOT need to download and install this optional component. It will not have any effect on the hydraulics or hydrology product you have functioning.
In WaterCAD/GEMS or HAMMER - First, you will want to select the desired scenario and time-step.
- File > Export > Publish i-model
The following dialog opens with the defaults set so that all elements and properties are included in the i-model.
- The top left pane is a summary of the element types to be included in the i-model. If a box by the element type is checked, that element type is included. The Table/Properties column reflects the selections on the right side of the dialog in terms of which elements and properties are to be included.
- The bottom left portion of the dialog box is used to identify which elements are to be included in the i-model.
- If the "Publish a subset of elements based on the Flex Table filters" box is checked, only those elements that are in the filtered flex table will be included in the i-model.
- If the "Exclude topologically inactive elements" box is checked, only active elements (Is Active? = True) are included in the i-model.
- The user will usually not need to include all element properties in the i-model. The right side of the dialog is to identify which properties of the elements are going to be included in the i-model. The default is "all properties". If the user wants to only include a subset of peoperties, the user should create a flex table with only those properties and select that flex table from the drop down list.
