Parallel Index Lines
Description
The Parallel Index (PI) Lines facility allows up
to fifteen index lines to be displayed
simultaneously. PI lines are available in all
presentation and motion modes. The lines
span the entire chart display in both primary
and secondary display modes, irrespective of
the scale ratio in use.
Each PI line is defined by the range of its
closest point to own ship, its bearing, line type
and which side of the ship the line is on.
To access PI lines left click on the Parallel Index Lines field from the NAV
Tools menu list. The PI Lines window includes the following three tab
folders:
•
Edit - where all PI line and PI set editing functions are done,
including adding a set or line, copying, deleting or renaming a set of
lines, or realigning a line or set of lines to own ship’s current heading.
•
Display - enables selection of one or more PI sets to be displayed on
the screen.
•
I/O - where import and export of PI Line sets is done.
Multi-node Support
Sets of parallel index lines are saved and retrieved in a database, shared
between all nodes. The set of parallel index lines displayed on a particular
node may be specified independently for each node.
Edit Parallel Index Lines
The Edit tab folder opens as default when
Parallel Index Lines is selected, and the
Selected Set shows
<Default Set> . Information
on PI lines associated with the default set is
displayed in the
Line Data section of the folder.
The <Default Set> of PI Lines cannot
be deleted or renamed.
To select a previously created set of PI lines click on the drop down arrow
to the right of the
Selected Set field and select from the list. The selected
set is displayed on the screen and is available for editing.
