Add Overlay displays the Overlay Types dialog allowing you to add a new overlay.
The Overlay Types dialog shows all available overlay types grouped under six tabs:
Recently used (shown when overlay selections have been made)
The Overlay Types dialog opens to show the overlays available under the Files overlay group.
A dataset read from a file on disk.
The SIS Workspace Definition (SWD) stores a link to the dataset. If the dataset is modified, then all SWDs with links will reflect the changes.
Click here for the full description of the File overlay type.
An editable dataset file in various formats. The dataset file can be shared by many users, and linked to many SIS Workspace Definitions.
Some formats only allow one user at a time to edit the file (file-level locking), others allow multiple users to edit (item-level locking).
Click here for the full description of the Create new file overlay type.
A dataset imported from a file on disk.
The contents of an imported dataset are copied into the SIS Workspace Definition, so they can be edited without affecting the original file.
