[in, out] variant safe array – An
array that contains triplets of doubles. Each triplet is composed
of an x-coordinate, a height, and a y-coordinate. The COM interface
represents the height in meters while the x- and y-coordinates are
represented in MPT units. You can use the ITerrain interface to
retrieve information about the MPT units. If you are working in
Lat-Long format, the Lat-Long values are in decimal Lat-Long.
See: “Creating a
Polyline Using a Safe Array”, for more details on how to create
and use a safe array.
