2. Classify the model objects in Organizer

Property categories has circular icons.


3. Create custom property for the classification code

In Organizer Settings dialog create a custom property that corresponds to the classification system you want to use. Custom property is a UDA. Add it to objects.inp file to see it in the User Defined Attributes dialog.

Add Name, Property (no spaces) and change Property type to UDA.

4. Add the new custom property to a property template in Object Browser

Search for the new property and drag and drop it to a selected template.

Click Modify and close the Settings dialog.

5. Add the new custom property to a category

Double click the root category to open the Category property dialog of the classification system.

Add the custom property by typing its name into the Object properties section.

Click Modify to save the changes.

Now all subcategories under this root have the same custom property. The lowest subcategories will add it to the objects with the given values.

6. Set value to the custom property to add it to the objects

Open the Category Property dialog of the lowest levels of the tree.

Add the value to the custom property that you want to write to the objects in the selected category.

7. Synchronize the category tree to write to the objects

Wright click on any category under the root and select Synchronize the category to add the custom property and its values to the model objects.

8. Check the result

You can check the result in the inquire dialog of the objects or in Organizer.
