Layer

Tool

Create a new feature layer. You can use a feature layer to create new features or edit existing features.

You can copy existing features to a feature layer using the Import Selected Objects command.

You can save the contents of a feature layer using the Save command. By default the contents of the layer will be saved to a HOB file or an H2O file, depending on the catalogue of the layer. If the catalogue meets any of the following criteria, the layer will be saved as an H2O file, which is a CARIS feature-based format:

the catalogue contains custom object acronyms that are longer than 6 characters

the catalogue contains attributes with multiplicity, which is specific to S-100

the catalogue contains information type objects, which is specific to S-100

the data type of the catalogue is S-100

If you close a feature layer or exit from CARIS, you will be asked if you want to save the feature layer.
