Check Sub Model for Updates

When you open the main model, the sub models are opened in the state they were in when you last saved the main model.

Upon opening the main model, the program automatically loads the sub models for up-to-date checking. The program checks whether the geometry of the sub model, materials collected to the components.xml file, panel drawings or part drawings are up-to-date, and you can choose what information you want to update.

If the sub model is not up-to-date, it is highlighted in a different color in the object tree:

The up-to-dateness of sub models is also checked when you create a material report of the main model to an Excel file or export the model to an IFC file.

If the model hierarchy is deep and the buildings are located on a server, loading the models automatically can slow down the opening of the main model. It is possible to prevent the automatic loading by turning off the Load model automatically option in the model hierarchy settings. An unloaded sub model is represented in the object tree in a different color:

You can load and check the up-to-dateness of a certain sub model even when the main model is open as follows:

1. Select the sub model.
2. Do either of the following:
   • Select Sub Project | Check for Updates.
   • Right-click to open the context-sensitive menu, and select Check Sub Model for Updates.
3. If the sub model is not up to date, the Sub Model Status dialog box opens. Select the data to be updated in the dialog box.

   If the sub model is up-to-date, the dialog box does not open.
