Cadcorp SIS Workspace Definition (SWD)

SWD is short for SIS Workspace Definition.

The list of overlays in a view (including any overrides or filters) is a SIS Workspace Definition (SWD).

When you save this view or definition, it automatically becomes an SWD file with the extension .swd.

TIP: An SWD file simply represents the last saved view of your data.
