Working with Feature Classes

Editing Feature Classes

Use the Data Model Administrator to modify the following feature class properties:

  • Feature class caption. Set or reset the feature class read-only.
  • Model Feature Class. Assign a model feature class. See Data Model: Model Tables.
  • Point Feature Class Settings—Digitizing Settings.
  • Geometry Settings—Edit Spatial Relate Settings.
  • Feature Explorer Settings—Define which feature information will be displayed in the feature explorer. See Customizing the Feature Explorer.
  • Job Settings—For topics: Assign a perimeter feature class and buffer to all feature classes of the topic. The Job Settings tab is only available if the industry model is job enabled.

Adding Attributes to a Feature Class

When you create a feature class with the data model administrator, it has default attributes that are specified by the feature class type. However, you can add more attributes.

Setting a Feature Class Read Only

Set a feature class to read-only so users cannot update and delete the data. This read-only property is achieved by deactivating commands in the user interface and not by Oracle rights. Oracle commands, such as insert, are still available from the Oracle side.

Examples

  • Use this option for feature classes that store imported data, which is not managed by the industry model .
  • Use this option when you create a feature class from a view.

For read-only feature classes the following commands are deactivated:

Administrator functions

  • Empty Feature Class
  • Update length/area attribute
  • Compound processing: eliminate/build/convert
  • Update Label Texts

Client functions

  • Digitizing
  • Creating new features
  • Dimensioning
